Starting January 16th 2023, Microsoft is no longer accepting driver submissions for WHQL certification on Windows 7. Please follow below guidelines to install your driver correctly on your system.
and results in "Bcdedit.exe -set TESTSIGNING ON’"
As another solution, User Sora states in the NVIDIA thread:
"Users can self sign both the catalog and service binary and inject that signature into the trusted root certificate location.",
but in my opinion it's too complex for John Doe (I had to change selfsigned server certificates to Internal CA root the last weeks, no fun ).
Unsure if installing critical drivers (audio & video: I assume to block obscure riping drivers for movie copy protection) selfsigned without cross signing by MS really works... but if so, it would be more convenient Virtualbox delivering Win7 guest addons in two packages:
- one for SHA-1 (without the SHA-2 fix),
- the other for SHA-2,
(maybe checking SHA-2 availability while installing ?)
Just a thought...
