Windows BCM20702A0 driver

Bluetooth problems in Windows computers are often related to incorrect or missing drivers for a Bluetooth device. In the case of the Broadcom BCM20702A0 device, the right BCM20702A0 driver is required for the device to function in Windows. Otherwise, the device will not work and show an error. Any other Bluetooth devices depending on the BCM20702A0 device will most likely also not work or not be recognized.

What is BCM20702A0?

BCM20702A0 refers to a Broadcom Bluetooth 4.0 chip. It is often used in USB Bluetooth dongles, but can also be embedded directly in a computer (laptop, desktop, or all-in-one PC). The chip implements Bluetooth communication which allows a Windows-based PC with this device to connect to external, wireless devices that support Bluetooth. Examples are headsets, game controllers, printers, mice, mobile phones, and similar.

Since the BCM20702A0 chip is used on hardware solutions from different manufacturers, a driver specific to the manufacturer may be required to ensure the BCM20702A0 device is recognized by Windows. Dell, Lenovo, Asus, and others all have drivers available for hardware using the Broadcom BCM20702A0 chip.

BCM20702A0 Related Problems

If the BCM20702A0 driver is not installed, or not compatible with the installed device or Windows version, there will be an error. In the Windows Device Manager, the device will be listed under the Other devices category. An exclamation mark on the device icon indicates it is not working properly.

The possible error message for not working Bluetooth devices in Windows:

This device cannot start. (Code 10)

The drivers for this device are not installed. (Code 28)

In Windows 10 and Windows 11, the message will say “There are no compatible drivers for this device”. Instead of “There is no driver selected for the device information set or element”.
This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

In normal circumstances, all working Bluetooth devices will show in the Bluetooth category in the Device Manager. But if the right driver is not installed, this category might not show at all.

The result of a non-working Bluetooth module is that Windows will not be able to connect to any Bluetooth devices. Pairing with Bluetooth devices will be impossible.

Steps to solve BCM20702A0 problems in Windows

The most common cause of the problems related to the BCM20702A0 device is a driver problem. So, in solving the error, the first steps are focused on getting the right driver installed. If after that, the device still does not work, try the other methods to fix the issue.

Before starting with the steps, make sure that the Bluetooth USB dongle is plugged (in case an external Bluetooth solution is used). Trying to solve the Bluetooth problem without the device physically present in the computer will not work. This sounds silly but it is better to check than wasting time trying to fix a non-issue. Also, make sure you reboot your computer. Pending restarts after updates can be the source of problems.

Update the BCM20702A0 driver from the Device Manager

The Device Manager is the most common method to install and update drivers for devices in all Windows versions. So, try these steps to update the driver.

Press the Windows + R keys to open the Run dialog box.
Type devmgmt.msc in the Run box and press Enter or click OK. This will open the Device Manager.
In the Device Manager window, locate the problematic Bluetooth device in either the Other devices category or the Bluetooth category.
Right-click the BCM20702A0 device and in the popup menu, select Update Driver Software (Update driver in Windows 10 and Windows 11).
Use the Search automatically for drivers option to let Windows find the correct driver for the device. Click Close when the driver has been installed.

In case Windows does find a driver for the device, a driver will need to be manually downloaded from the manufacturer’s website.

Manually download the BCM20702A0 driver

If Microsoft has not included a driver for the BCM20702A0 device in the version of Windows that you are running, a driver will need to be added manually. This means a Bluetooth interface driver needs to be downloaded from the manufacturer’s website. Check your computer brand and model and locate the manufacturer’s support website to search for the driver.

Note: Broadcom used to support their own version of the Bluetooth software, including drivers. This generic WIDCOMM Bluetooth Software is no longer maintained and supported.

Once downloaded, run the setup or install program for the driver package to install the driver in Windows. Note that a user account with administrator privileges is required to install drivers.

If a driver is not available for your Windows version, you can try running an driver for an older Windows version in compatibility mode. For example, say we are running Windows 10, but the Dell installer for the Bluetooth module is suited only for Windows 7. If there is no Windows 10 driver available, we run the Windows 7 installer as follows:

Right-click the downloaded installer file.
In the popup menu, select Properties.
In the file properties dialog box, select the Compatibility tab.
Under Compatibility mode, select the checkbox for Run this program in compatibility mode for (1), and select Windows 7 in the dropdown box (2).
Click OK to confirm and close the properties dialog box.
Now execute the driver installer again.

Important: The driver needs to match the Windows architecture in order to work. Installing a 32-bit driver on a 64-bit system will not work, even in compatibility mode.

If the downloaded driver package does not have a setup or install program, you need to manually install the driver using the Device Manager.

Update drivers using Microsoft Update

Microsoft has included support for many devices in every updated version of Windows. Although that means that many devices are detected and supported directly, some devices require optional updates. In Windows 10 and Windows 11, optional updates often include updated drivers for devices. To check if the Broadcom BCM20702A0 driver is available, follow these steps.

Open the Settings windows from the Start menu.
In the Settings window, select Windows Update.
In Windows 11, click Advanced options (skip this step in Windows 10).
Next, click View optional updates.
Under Optional updates, click the Driver updates entry to expand the list and see the available driver updates.
If there is an entry for the BCM20702A0 driver, select it and click the Download and install button.

If no driver update is available for the Bluetooth device, the BCM20702A0 device is not supported in Windows. At least not by Microsoft directly. You will need to use the steps to manually download the driver to get it to work.

Restart the Bluetooth Services

This is the first of the steps that do not directly relate to the BCM20702A0 driver. Even if the driver is installed, the device can still give an error. The error might be solved by one of the following solutions.

Windows uses several services (background tasks) for making sure the Bluetooth devices and functions can work. In some cases, a service may have a problem, and manually starting or restarting the service can fix the problem.

Here are the steps to restart the Bluetooth services in Windows.

Press the Windows + R keys to open the Run dialog box.
Type services.msc in the Run box and press Enter or click OK. This will open the Services window.
In the Services window, locate the Bluetooth Support Service and right-click it.
In the popup menu, click Restart.
Close the Services window when done.

You can repeat these steps for other Bluetooth services, like the Bluetooth Driver Management Service. If the services are not in a Running state, simply try starting them instead of restarting them. Not all Bluetooth services need to be running for the BCM20702A0 device to be detected and installed. Some are for support tasks, like audio over Bluetooth. But starting or restarting them manually ensures that they are not the reason the device is not working.

Run the Bluetooth troubleshooter

In Windows 10 and Windows 11, there is the possibility to run a Windows troubleshooter for a number of problems. Microsoft has included a troubleshooter function for common problems that can be automatically solved. One such troubleshooter is the Bluetooth troubleshooter.

To execute the Bluetooth troubleshooter in Windows 10, follow these steps.

Open the Settings window from the Start menu.
In the Settings window, select Update & security.
Next, click Troubleshoot in the left-hand pane.
In the right-hand pane, click the Additional troubleshooters link.
Next, under Find and fix other problems, click the Bluetooth option.
This will show the button Run the troubleshooter. Click it to start the troubleshooter.
A new window will come up showing Windows is Detecting problems with Bluetooth. Wait for the process to finish analyzing and fixing any Bluetooth-related issues.
Click Close when done.

In Windows 11, the steps are a little different.

Open the Settings window from the Start menu (or press the Windows + I keys).
In the Settings window, click System.
Next, click Troubleshoot in the right-hand pane.
Click the Other troubleshooters link.
Click the Run button next to Bluetooth under Other.
Wait for the troubleshooter to finish analyzing and fixing any Bluetooth-related problems.

Note: The Bluetooth troubleshooter can take considerable time to complete.

Check the Airplane mode setting

This is mentioned as one of the last solutions since the option would normally only be used on portable devices for a specific reason. But if you have been traveling with your laptop, it is a step that is worth taking.

Personally, I simply disable the Bluetooth option in Windows and only enable it when needed. Active communication on any device is a security risk these days. But if you have Bluetooth turned in normal circumstances, you can opt to use the Airplane mode in Windows to disable all communication when traveling.

In both Windows 10 and Windows 11, the Airplane mode can be enabled or disabled by clicking the network icon in the taskbar and selecting the Airplane mode in the quick access popup window.

Note that the Airplane mode will show active when enabled (blue in this example but that will depend on the active Windows theme). Airplane mode should be disabled for Bluetooth to work.

If you prefer to use the Windows Settings, follow these steps.

Open the Settings window from the Start menu.
In the Settings window, click the Network & internet option.
Next, click the Airplane mode option.
Now make sure both switches are in the Off position.

In Windows 11, you have the option to disable the Airplane mode directly, or like in Windows 10, select the Airplane mode option to control the individual settings.

Windows 11 remembers which communication was on when you enable and disable Airplane mode. So, if only Wi-Fi was on and Bluetooth was off when airplane mode was activated, Bluetooth would remain off when airplane mode is disabled again. This is why it is a good idea to check this setting.
Close the Settings window when done.

After this, the network and Bluetooth devices should be working. There is no need to restart the computer, the changes take effect immediately.

Reset the hardware devices

Windows keeps configuration information for all devices in the computer. In rare cases, the configuration of a device can be a problem. Installing similar devices with similar drivers, or installing additional USB devices on the same controller can result in a BCM20702A0-based device to stop working.

To fix the issue, it is possible to reset the device by removing it and letting Windows reinstall the device with the proper configuration settings. These steps need to be executed from within the Device Manager.

Follow the steps to update the BCM20702A0 driver from the Device Manager, but instead of picking the Update driver option, select the Uninstall option. In the Uninstall Device confirmation window, click the Uninstall button (1). This will remove the device from Windows. After this reboot to let Windows automatically detect and reinstall the device.

First, try the uninstall option and keep the drivers installed. If that does not fix the issue, use the option Delete the driver software for this device when uninstalling it (2). That will force Windows to reload the driver for the Bluetooth device.

If the BCM20702A0 device is a USB dongle, it can also help to uninstall the USB Host Controllers in the Universal Serial Bus controller category. These controllers ensure that all connected USB devices are detected are installed. Resetting them can solve problems caused by the USB interface itself.

If things are still not working after this, then you might still be able to get things working again. That partly depends on whether the BCM20702A0 device was working on your system previously. If it was, a system restore or system recovery can bring back the working BCM20702A0 driver.

For help in finding the right drivers for your Windows devices, including the BCM20702A0 device, you can use the DriverFinder program. By scanning the hardware present, it will locate and offer the required device drivers.

How to Fix Driver PNP Watchdog Error on Windows

Critical errors in Windows result in a blue screen showing the error details. The DRIVER PNP WATCHDOG error is one of these types of errors. Depending on the Windows version it will also show error code 0xc1900101. As the error message already indicates, the error is related to a driver and to something called PNP. PNP refers to plug-and-play and is basically a concept that allows devices in computers to be automatically detected and installed.

The error mostly occurs during a Windows installation or an upgrade. Since the error relates to a driver, which operates on a high-security level in Windows, the error results in the operating system being halted.

Causes for the Driver PNP Watchdog Error

Like any BSOD error on Windows, it is best to check the crash dump or minidump if available. The Microsoft WinDbg tool can be used to analyze a crash dump file. This process will help identify which driver caused the crash. That does not always mean the driver itself is causing the problem, but it helps pinpoint where to look for a solution.

The most common causes for this problem are disk or disk controller related. The inability to read or write data at some point can cause the blue screen error. Disk controllers, USB controllers, Raid controllers, and SATA controllers, all need the right driver to prevent problems. But even a faulty SSD can cause this type of error!

Steps to fix the error

I suggest you also have a look at the article to solve the BSOD related to power state failures. In this, the general approach to fixing BSODs is outlined and many of those steps will apply to the PNP Watchdog error as well.

Windows will not boot at all

If your Windows device does not start at all, this will limit the troubleshooting options. The first thing to try is to start Windows in Safe Mode. If that succeeds, you can execute some, if not all, of the steps in the section Windows will still boot.

If Windows will not start at all, the only options are to use a bootable USB stick for your Windows version.

Make sure you can boot from the USB by configuring the BIOS options.
Make sure you have a UB stick with a bootable copy of Windows on it.
Plug the USB stick into a USB port and reboot the device.
When the screen shows Press any key to boot from USB, press a key.
When the Windows install screen comes up select the option Repair your computer in the bottom left. This will restart the device again and get you to Advanced Recovery.
Select the Advanced options to see more troubleshooting options.
Next, select Troubleshoot.
You can now try the Startup Repair option, use the Command Prompt for disk checking options, Uninstall Updates to revert to a previous configuration, change UEFI Firmware settings to configure the hardware of the device, or use System Restore if you have any previous restore point that can be used to restore the system.

Note: For Windows 10, the options are slightly different, but offer similar recovery and repair options.

If none of these steps work, try resetting the BIOS or UEFI to load the default options. The Advanced Configuration and Power Interface (ACPI) feature of the BIOS will allow devices to be configured automatically in most cases, which will ensure correct settings. Apart from that, try the diagnostic options in the BIOS/UEFI to test the hardware. If a problem is found at the hardware level, a component might need to be replaced. Setting a SATA controller to IDE has also helped some people solve this problem.

Although a bit more hands-on, check the cables in the system. A loose connector on any of the internal devices (not just storage related) can cause the error.

If the solutions so far don’t work, the only remaining option is to completely reinstall Windows from the bootable USB. I would recommend formatting (or initializing) the drive you will install Windows on. If there are any problems with the disk they can be detected during that process.

Windows will still boot

If you can still start Windows, there are more options to troubleshoot and fix the Driver PNP Watchdog error. Use the steps below to try and solve the error. The sequence is not critical, as any of these steps can provide the solution to the error depending on the actual cause of the problem.

Use the Disk Manager to make sure the disks in the system are properly detected and file formats are correct.

Disk Management can be started by right-clicking the Start menu button in Windows 11 and selecting Disk Management in the menu. It is also accessible in the Computer Management
If you are using an SSD, check your drive with a third-party tool. Most manufacturers provide software for this (e.g. Samsung Magician, SanDisk Dashboard, Intel – Solidigm Storage Tool).
These tools can tell you if the SSD is functioning properly and if the drivers are working correctly.
Use the standard Windows command line tools to check the disk and check the system files.
Run a command prompt with administrator-level privileges and then run these commands:
CHKDSK /F /R
SFC /SCANNOW
The first command runs a disk check with options to fix errors on the disk and locate bad sectors. The second command scans for the integrity of the Windows system files and repairs any errors found as far as possible.

Note: If the drive is in use, you can opt to run the disk check at the next startup. This will happen when you run the chkdsk command on a system drive.
Use the Device Manager to check the device drivers.
Open the Device Manager from the Start
In the Device Manager window, right-click the devices and use the popup menu option Update driver to make sure the latest driver is installed for the device.

Start with the devices under the Storage controllers and Disk drives categories.
If you were able to use the WinDbg tool to pinpoint the driver causing the crash, then focus on that device. It may also be possible that you need to do a driver rollback rather than an update. A newer version of the driver can just as easily cause the error as an older version.

Hopefully, the above tips will help you solve your Driver PNP Watchdog error and enable normal use of Windows. If you have any different experiences with this type of error, including alternate solutions, please do leave a comment.

For help finding any new, missing and updated drivers, we suggest using the DriverFinder software.

A driver cannot load on this device ene.sys

When you are updating Windows 11 to the latest version, you might see an error pertaining to the file called ENE.SYS. The error indicates that the device driver cannot load. This problem is a result of the security settings in Windows 11 in combination with an older version of the ene.sys file.

What is ene.sys?

The ene.sys file is a driver file. Like other .sys files on Windows systems, it is a device driver that enables the communication between Windows and a hardware device. The ene.sys file is part of a system called MSI Mystic Light, which controls lights in a PC. This is typically used in gaming systems and is used by MSI for their gaming systems.

Mystic Light is installed as part of the MSI Dragon Center or MSI Center.

There are a few methods to solve the error related to the ene.sys file not loading. Below you will find the details on these options with instructions on how to execute them.

Option 1 – disable the memory integrity check

To enhance security Windows 11 has an option called core isolation. You can read all about it on the Microsoft website, but in short, it is a memory security feature that helps prevent critical components from being affected by malware or crashing the system.

Disabling this feature can solve the loading problem with the ene.sys file since the driver will be allowed to load afterwards.

To disable the core isolation (memory access protection) in Windows 11, follow these steps:

Open the Windows 11 Settings from the Start menu.
In the Settings window, click Privacy & security option in the left-hand pane (1).
Next, click Windows Security in the right-hand pane (2).
Scroll down in the list of Protection areas until you see Device security and click it. The Windows Security window will open with Device security active.
Now click the Core isolation details link.
Toggle the option Memory integrity to Off.

Changing the Memory integrity option to Off will allow incompatible drivers to be loaded. That includes the version of the ene.sys that was shown in the initial error message.

As you will realize, this change will reduce the level of security on your Windows 11 PC. So, it is not the most desired option, but if no newer driver is available, it is the only option to load the driver.

Option 2 – Updating the ene.sys driver file

The better option to deal with the incompatible driver is to install an updated version of the device driver. Installing a later version of the ene.sys file can fix the problem. This will allow the Memory integrity check to be enabled and load the ene.sys driver at the same time.

To update the Mystic Light version for MSI, you use the MSI Gaming Center software. Or for Windows 11, the new MSI Center software. The MSI Center can be downloaded from the MSI website.

After downloading and installing the MSI Center, run it to find the Mystic Light option and click the Update button. If the Mystic Light is not in the Installed list, find it under the Installable items and install it to get the latest version.

Once the installation of the new Mystic Light version is complete, enable the Memory integrity option in Windows 11 again.

Windows 11 will check the drivers installed on the system for compatibility.

If all drivers are compatible, the option will be enabled and the Core isolation will function properly.

In case a driver is found not to be compatible, Windows 11 will show a message in the notification area.

Click the Review incompatible drivers link in Windows Security to find out which drivers are incompatible.

Non-MSI vendors

What if you never used an MSI hardware product? There are other light control products used by different vendors that use the ENE solution as well. Have a look at Trident Z Lighting Control by G.SKILL, ASUS Aura, Gigabyte RGB Fusion, and NZXT CAM. SignalRGB is a non-vendor solution for RGB sync.

It is important to only install one of these solutions though, as they can use similar software components that interfere with each other’s operation.

In general, we recommend keeping device drivers up to date. Using the latest versions ensures the most recent digital certificates on the driver files and the best compatibility with Windows 11. Use our DriverFinder program if you have trouble finding an updated driver.

Manually remove ene.sys and related files

In case you cannot fix the problem by installing, updating, or uninstalling software related to light sync, you might need to do a manual cleanup of anything related to ENE.SYS.

That means checking the Program Files folders on your system for any ENE subfolders and deleting them. Then search for ENE.SYS and ENE.DLL on the system disk and remove those files as well.

It can even be enough to simply rename the ene.sys file in the Windows driver folder. Just do a file search in the C:\Windows\System32\Drivers or C:\Windows\System32\DriverStore\FileRepository folder for the ene.sys file and rename it to ene.sys.old or something similar. You will need administrator access level for this.

The last step is to search for ENE in the Windows Registry and remove any entries related to the driver. Make sure to make a backup of the Registry first by using the Export option in the Registry Editor! Adter creating a backup, use the Edit -> Find menu option to search for any ene.sys entries and remove them.

Note: Make sure to repeat the search after every occurance found and deleted using the Edit-> Find Next option (F3).

Windows 11 – Direct RGB Support

The best solution to the problem would of course be that there is no need for the ene.sys driver. At the moment there is no direct support for RGB lighting control for gaming in Windows 11. Microsoft seems to be working on this though. In Windows 11 build 25295, lightning controls have been found in the settings that seem to indicate Microsoft is implementing things directly into Windows 11! Original Microsoft specifications for this are from 2018.

Fix Video DXGKRNL Fatal Error in Windows

The DXGKRNL fatal error in Windows is a Blue Screen of Death error (or STOP error) that will halt the operating system. A critical error in the DirectX software system causes this error.

When this error occurs, you will see the BSOD with the error message. Depending on the Windows version, the system will halt, or Windows will try to recover by scanning for problems.

Cause of the DXGKRNL Fatal Error

As mentioned, the problem is related to the DirectX graphics system that is installed in Windows. DirectX is a library that enables software to interact with the PC’s video and audio hardware. It is mainly used by gaming software. DirectX has been part of Windows since XP (version 9.0) until Windows 11 (version 12).

DirectX allows software to use the multimedia accelerator features of your video and audio hardware for great performance. But to do this, DirectX operates at a high security level in the operating system. So, if something goes wrong, problems are serious for the operating system.

What can go wrong? Well, mainly device drivers and DirectX itself. DirectX uses objects and drivers that execute at kernel level, and it also interacts with devices through device drivers for the video and audio hardware. Any problem with the DirectX file or configuration, or a problem with the device drivers can cause the DXGKRNL fatal error.

Solving the DXGKRNL Fatal Error

There are two main solutions to fixing the error. The first is updating or reinstalling DirectX, and the second is updating or reinstalling the device drivers for video and audio hardware.

If you can still boot into Windows, you can execute the steps to solve the error. If Windows won’t start anymore, try using the Safe Mode boot. In that startup mode, Windows only uses a standard video driver with minimal features. For Windows 7 and Windows 8, the steps are different. Press F8 during boot to get into the Advanced Boot Options screen and select Safe Mode.

DirectX in Windows

With most software, you would simply say: uninstall it, reboot, and then reinstall it. That was possible for older versions of DirectX as well, but not in the latest Windows versions. DirectX is an integral part of Windows in the latest Windows versions.

For Windows 7 there was still a separate update that can be downloaded to install DirectX 11.1.

For later Windows versions, you simply need to make sure you run Windows Update.

In Windows 10, open Settings, select Update & Security and click Check for updates.

In Windows 11, open Settings, select Windows Update and click Check for updates.

DirectX Diagnosis

To check the version, and any potential problems, you can use the DirectX Diagnostic Tool. This tool is part of the DirectX installation and can be started by typing “dxdiag” in the Start menu search box.

After starting the dxdiag app, you will see the details of the DirectX installation.

With the System tab active, the DirectX Version can be seen at the bottom of the list with System Information.

Use the Next Page button to jump through the pages, or simply use the tab selectors to switch directly to the Display, Sound, or Input options.

In the Display tab, you can see which features are enabled. The Notes section will show any problems with the DirectX functionality. The Notes section is present for all tabs.

If a DirectX feature is Disabled, it might either disabled in the settings, not be supported by your PC hardware, or not supported due to driver limitations.

Update the Display Driver

If the DXGKRNL fatal error is caused by a device driver, the first step is to update the driver to the latest version. Updated drivers can have bug fixes, performance improvements, and feature enhancements.

To update the display driver in Windows, use the Device Manager.

Open the Device Manager using the search box in the Start menu, or press the Windows key + R and type devmgmt.msc in the Run box followed by the Enter key.
In the Device Manager, expand the Display adapters category by double-clicking it.
Next, right-click the listed graphics adapter, and in the popup menu, select Update driver.
Use the option Search automatically for drivers to let Windows check for graphics driver updates automatically. If you have downloaded the latest graphics driver for your computer manually, use the option Browse my computer for drivers and select the location.
Once the updated driver is installed, click Close and close the Device Manager.

Next, restart the computer and see if the problem is resolved.

Uninstall the Display Device to fix the DXGKRNL error

There may be no driver update available for the graphics card. Or an update is available, but the update did not fix the problem. In that case, the driver configuration may be a problem. Uninstalling the display device can then help solve the error.

Uninstalling a device and then restarting the PC will force Windows to reinstall the graphics device. If the driver was also deleted during uninstall, the driver will also be downloaded and installed again.

Use the instructions from the previous section to open the Device Manager and expand the Display adapters
Right-click the graphics adapter, and in the popup menu select Uninstall device.
In the Uninstall Device window that shows next, make sure to select the option Attempt to remove the driver for this device.
Note: for previous Windows versions this option is worded a little differently.
Click the Uninstall button to continue.

Once the device is uninstalled, restart Windows. The display device will be reinstalled during the restart with the latest driver.
Note: in case the display device is not automatically reinstalled, use the Scan for hardware changes in the Action menu of the Device Manager to force the device installation.

System Restore

None of the solutions so far working? If your Windows configuration is using System Protection, you can try the System Restore option to revert to an earlier, working configuration.

With every change, Windows can create a restore point that will help bring back a previous configuration. Here are the instructions for Windows 11.

Open Settings from the Start
Select System, and then About.
Scroll down to the Related links section, and then click Advanced system settings. This will bring up the System Properties.
In the System Properties window, select the System Protection
Next, click the System Restore button.
Click Next to show the list of restore points on your computer.
Select which restore point to use, and then click Next.
Click the Finish button to confirm the restore operation.
Click Yes in the confirmation window.

Windows will now create a restore point. Your PC may restart during the process. Just be patient and let the system restore complete.

After the final restart, see if the problem is solved.

Although this specific error is related to the display aspect, DirectX also uses sound and other media and input drivers. It is recommended to keep all device drivers up to date using DriverFinder.

cFosSpeed Driver for Windows preventing Windows 11 update

When you are finally ready to upgrade from Windows 10 to Windows 11 and your system is meeting the system requirements, you can still run into issues that prevent the upgrade. The cFosSpeed Driver can prevent the upgrade to Windows 11, as the Windows Update process will report it as something that needs your attention. Essentially it states that “a service isn’t ready for this version of Windows 10 ”.

What is the cFosSpeed driver?

The cFosSpeed driver is an Internet accelerator software solution. The software optimizes Internet traffic on a Windows PC by installing a device driver. The driver performs something called traffic shaping. It has some advanced network analysis and optimization integrated, but it also allows for the prioritization of streams or protocols. This is great for video streaming and gaming.

How did cFosSpeed get on my system?

The solution is integrated with quite a few OEM vendors. Manufacturers like MSI, Asus, ASRock, and Gigabyte include the cFosSpeed software in their driver bundles for their motherboards. In the case of Asus, you might know it as Turbo LAN, which is a rebranded version of the cFosSpeed software. With MSI it is part of the Dragon Center.

Fix cFosSpeed from blocking the Windows 11 Update

Considering the problem of the cFosSpeed driver blocking the Windows update, there are two solutions to the issue with the cFosSpeed driver. The first is to update the driver to a version that does not block the Windows 11 update. The second option is to uninstall the cFosSpeed driver from your Windows installation.

Update the cFosSpeed driver

The first option to update the driver is to check the OEM support site for an updated version of the software that includes the cFosSpeed driver.

For Asus, check their support site and look up your model to see if a new version is available. If so, download it and install it and then try the Windows 11 upgrade again.

For MSI, download and install the latest version of the MSI Dragon Center and after completing the installation, try the Windows 11 upgrade again.

For Gigabyte you will need to download the cFosSpeed Internet Accelerator Software from their site. Check the support section for your motherboard or model.

For ASRock, the cFosSpeed driver is part of the XFast Lan solution. It can be downloaded from here.

The last option is to download the latest cFosSpeed software from the vendor’s site and install it. Take note that this is a shareware version, which is valid for 30 days. But it should update your cFosSpeed driver so that you can upgrade to Windows 11.
Update: the software is now owned by Atlas Tech Solutions and their latest version is 13.

If you have the original cFosSpeed software installed and running, you can click the cFosSpeed icon in the Taskbar, and then in the popup menu select Get latest version.

Uninstall the cFosSpeed driver

If the driver update did not solve your issue, and you can still not upgrade to Windows 11, the best option is to uninstall the cFosSpeed driver altogether.

Uninstall the cfosspeed APP

Steps to uninstall cFosSpeed in Windows 10:

Open Settings from the Start
In the Settings window, select Apps.
By default, Apps & features should be selected. If not, select that option in the left-hand panel.
Now scroll down in the apps list until you see the cFosSpeed entry (it will include a version number in the name).
Click it, and then click the Uninstall
When prompted “This app and its related info will be uninstalled.”, click the Uninstall button.
When the UAC (User Account Control) windows pops up, click the Yes option to allow the uninstaller to run.
Follow the instructions in the cFosSpeed Uninstall Wizard to uninstall the app.
If for some reason this does not work, it is also possible to uninstall the cFosSpeed from the Network Properties.

uninstall the cfosspeed driver

Open the network properties for an active adapter, select the cFosSpeed for faster Internet Connections (NDIS 6) entry, and then click the Uninstall button.

You will again be prompted for a confirmation. Click the Yes option to uninstall the cFosSpeed driver.

After completion, the entry will no longer show in the Network Properties list.

There is no need to repeat this for any other active network adapters. Once uninstalled, the cFosSpeed driver will be removed from all network devices.

Note: Uninstalling the cFosSpeed software using the network option will only remove the Lan Manager component, which is the network driver. The cFosSpeed main application, if installed, will still remain. So, if possible, use the App uninstall option to uninstall cFosSpeed.

After uninstalling the software, try the Windows 11 upgrade again.

If the upgrade still fails, you may need to consider doing a fresh install of Windows 11 rather than an upgrade from Windows 10.
