When they started with driver signing there was a “Peter Pontificates” with the headline "It's not your computer" and I have now run in to two issues that can be worth mentioning.
- If I do a clean install of Windows 11 on a new computer that has secure boot enabled the driver for the sound chip will never load until I turn off something called “memory integrity” in a section called “core isolation”. This is despite that the sound driver is not only signed, it is WHQL signed and distributed by Microsoft! (however it was a third party driver)
- Again, if I do a clean install of Windows 11 and enable test signing I can only load my drivers for a few days up to a week then I got a message that they have “increased security” and loading drivers stop working. After turning off all security features I could find it was still not working and the reason was that this time it was not the driver that was the problem but the program that starts it! Even if I have enabled testsigning and run as administrator I am not allowed to run the program that starts the driver! That is net/sc/osrloader or something like that so I must separately enable myself right to run that program to start a driver that I already has the right to run. Note also that this will turn up after a week or so on a new computer so before that you don’t know about this problem! Also I turned off a lot that could probably have been left on so the computer is not “clean” anymore.
