The printer drivers are not causing the problem.

The only option I can think of is to replace the DRIVERS hive by extracting a fresh copy from the ISO and running Display Driver Uninstaller (DDU) to completely remove NVIDIA drivers. However, you must take a complete OS image backup beforehand.

Please provide me detailed steps of the solution. Thanks!

Also, I want to exclude all system registries, components etc. that cause errors when creating a system image backup and only keep files, programs, settings, drivers, normal registry entries, components that makes the OS work etc. What should I do?

Could you provide me detailed tutorial?

Also, will the OS image backup back up the corrupted driver registry(including other system components that are causing current problems) along with other normal system components?

Before creating a complete OS image backup, I've some questions to ask you --

1.What's the approximate success rate of this method in solving the problem? How likely is this method to cause system problems?

2.Can I save the complete OS image backup in my PC's local disk? If so, if there is a problem with my system and it cannot be used normally, is USB drive available for performing a OS image recovery?

3.I've no any disks, I wrote the image of Kaspersky Rescue Disk 18 to my USB drive(https://support.kaspersky.com/us/krd18/howto/14226#block2) about three years ago, after scanning my PC, I was unable to return my usb's storage to normal, even after formatting, I was also unable to restore the free space to normal values.

Do you have any solution to the problem?

4. How can I recover the OS image if I don't have a available USB?

I don't know if corrupted registry keys would block uninstall operation, I just found the complete registry I backed up two years ago(I haven't found a more recent complete registry backup yet), can I fix damaged key via previous key? Will my system encounter any problem if I use the previous key to repair the damaged key?

Also, the comments on the reddit post made me think of another possibility --

"Yes they do. I believe OEM0.inf is a print driver and we uninstalled all printers from device manager and told the system to delete the driver.
Here is some of the contents of OEM0.inf

File Name:

;

; prnms009.inf

;

; Abstract:

;

; The Microsoft Print To PDF install file"(from Windows 10 to 11 Upgrade Failures)

"Yes, that does and it is the ms/office print to PDF."

Here is my analysis --

I was unable to uninstall it because the process is still running, Maybe I can directly uninstall the program corresponding to prnms009.inf and prnms001.inf and all associated drivers or uninstall them smoothly after activating core isolation.

What do you think about this? Could you give me some advices on how to uninstall oem0.inf(If you have better suggestions on uninstalling, please share them with me)?
