Windows 11 Memory Integrity bricks machine

Question

I turned on memory integrity, because MS flagged it as a warning, and it crashed my machine so hard I couldn't even get recovery to come up. I was finally able to convince the machine to boot into safe mode and use regedit to turn memory integrity off, which solved the problem. Before that, I turned logging on but I have no evidence anything was sent to MS so I'll post log below.For others who are stuck in the doom loop, I fixed it by booting into safe mode, running regedit and changing the following: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrityDouble-click the Enabled key and change its value from 1 to 0.This wasted an hour of my day, and I'm pretty unhappy that MS hasn't flagged this as an issue - it's clear memory integrity isn't working for people, and there needs to be a lot more robust debugging on MS's end to detect and bypass crash loops. I nearly reinstalled the OS the crash was so hard, and that's just stupid for a built in feature of the OS to fail so badly.Log file:DLOGFILE00010000DUMPi Dump stack initialized at UTC: 2024/09/05 15:00:06, local time: 2024/09/05 10:00:06. #BugCheckCode 0x0000000000000050 #BugCheckP1 0xFFFFD20CDB200000 #BugCheckP2 0x0000000000000000 #BugCheckP3 0xFFFFF80564038080 #BugCheckP4 0x0000000000000002 Progress 0x00000042 Elapsed BugCheck duration 00001802ms Starting get secondary dump callbacks size.

Answer 1

There is an underlying problem with Device security/Memory integrity - It functions on some branded PC's but not on others.

MSFT has been unable to identify/resolve the issue - I know as I have spoken with them at length.
