Update or reinstall the driver
This is the most common solution. This error is often caused by the driver file being corrupted, incomplete, or signature failure. You can try:
- Open Device Manager and find the device that reported the error.
- Right-click to select the device and click Update Driver .
- If it doesn't work, you can try uninstalling the device , then restarting the computer, and letting the system reinstall automatically.
- Or go to the official website to download the latest version of the driver and install it manually.
Sometimes the old driver and the new version of Windows are incompatible, and the problem can be solved after the update.

Disable forced signature verification (for temporary testing)
If you are sure that this driver is trustworthy but has not passed Microsoft's signature authentication, you can consider temporarily disabling signature verification:
- Press
Win X
and select Command Prompt (Administrator) or Terminal (Administrator). - Enter the following command and press Enter:
bcdedit /set testsigning on
- After restarting the computer, you will see a watermark of "Test Mode" in the lower right corner of the desktop.
?? Note: This method will allow the system to load unsigned drivers, but may also bring security risks. It is recommended to be used only in the test environment.

Turn off Secure Boot (UEFI secure boot)
Secure Boot is a UEFI feature that prevents unsigned drivers from running. Some old or third-party drivers may be blocked as a result.
The operation steps are roughly as follows:
- Enter BIOS settings (press F2, Del or other specified keys when restarting).
- Find the Secure Boot settings item.
- Set it to Disabled .
- Save and exit.
This step of operation varies slightly depending on the motherboard brand. For details, you can check the motherboard manual or search for the settings corresponding to the model.
Check if system integrity is damaged
If none of the above methods are useful, it may be that there is a problem with the system file. You can check it with the system's own repair tool:
- Open a command prompt as an administrator.
- Enter the following commands to execute:
-
sfc /scannow
-
DISM /Online /Cleanup-Image /RestoreHealth
-
These two commands can help you scan and repair system files. Restart after completion to see if the problem has improved.
Basically these common ways of dealing with it. It's not particularly complicated, but every step is very critical, especially when turning off Secure Boot and disabling signature verification, be careful not to correct other settings. When encountering uncertain situations, it is best to check it out first before taking action.
