[SOLVED] Memory Integrity bounces back to "turned off" state after Windows restart - fast ring 19536
This is an old post and the issue is no longer relevant. This has been happening since a couple of builds ago as well. I turn on the Memory Integrity in Core isolation section of Windows Defende...

I was seeing this issue as well and here is how I resolved it. After 2 weeks, it's stayed enabled after reboots, hibernate, etc. I do not have any incompatible drivers that would conflict with HVCI / Memory Integrity and turn this off, so it's not a driver causing this.
For me, the solution was to disable and then re-enable hibernate so a new hiber.sys file would be created with the necessary memory encryption for when "Memory Integrity" is ON. I primarily use Hibernate to shutdown at night.
1. Open an Admin Command prompt and execute the below to delete the hiber.sys file and bcd boot entries
powercfg /hibernate off
2. Turn on Memory Integrity and reboot.
3. Open an Admin Command prompt and enable hibernate.
powercfg /hibernate on
I tried this but unfortunately in my case it was not the solution. Problem persisted after new hiber.sys was created.
