The system is a Lenovo Helix notebook (3697CTO) with a front facing camera by SunplusIT. It was updated from Windows 10 version 1909 and when the Windows 10 camera app was opened the system crashed with a blue screen indicating that the camera driver SPUVCBv_x64.sys caused a system service exception.
Inspecting the problem file, the version was 6.0.0.1 with a file date of 27-Jul-2015.
The system was rolled back to 1909 and the camera worked fine. The driver file version at that time was 5.0.0.93 and dated 15-Mar-2013.
Checking the Lenovo website, the most recent driver available is 5.0.0.93 so the system was then upgraded to Windows 10 version 2004 and the camera drivers were uninstalled and reinstalled from the older Lenovo release (5.0.0.93). The camera app now works with the front facing camera.
Since the new driver is incompatible with the current hardware, how do I prevent Windows Update from replacing the original SPUVCBv_x64.sys file with a newer broken version?
