Summary0006103: Can't turn off test_signing/testmode
DescriptionThe Windows operating system is currently in Test Mode (allowing the use of unsigned drivers). If you switch to normal mode with unsigned drivers installed, the OS may fail to boot properly, resulting in an endless blue screen.

Therefore, before transitioning back to normal mode, it is necessary to sign the unsigned drivers!

It is also possible to have the drivers signed directly in VisualStudio when compiling them:
https://learn.microsoft.com/en-us/windows-hardware/drivers/develop/signing-a-driver-for-public-release
Steps To ReproduceCommands to exit Test Mode:
In CMD (run as administrator):

BCDEDIT –Set LoadOptions ENABLE_INTEGRITY_CHECKS
BCDEDIT –Set TESTSIGNING OFF

Then restart the system!

Caution: If there are still unsigned drivers, the OS may fail to boot properly, leading to an endless blue screen.
Additional InformationOn the board, you can check which drivers are signed using the following commands:

1. Click on Start – Run..., type `sigverif`.
2. Click on Start. After about a minute, all unsigned drivers will be displayed.
