What you want to ask is "What if you can't play unsigned games?" The solution is as follows:

1. Turn off the driver signature enforcement function: Press F8 when Windows starts, and select the "Disable driver signature enforcement" option in the entry window, which will stop the computer from performing forced signature detection when it starts, but this will pose a certain threat to the security and stability of the system.

2. Update drivers: download and install drivers with digital signatures, so that there will be no unsigned drivers.

3. Install unsigned drivers: Some drivers may not be digitally signed, but they can still run without causing system problems. If you believe that such a driver is safe, you can consider installing it, but please be careful.
