In new windows 11 up to date as of writing this. Core isolation memory integrity does not work and will not turn on. Every time I scan for incompatible drivers, none are listed. Checked the windows update, the system is up to date, and no errors in device drivers were found. All drivers appear up to date. BIOS most recent available (the same driver that was installed prior to this error occurring. None of the threads seem to address this, only ones where the driver is known. The DG readiness tool is not user-friendly for everyday users. Need a solution that can be done at home without having to be an IT guru or MSCE certified. It will not let me upload the screenshot or picture, keep getting errors in that as well.

I have the same problem and this is as far as I got with the instructions:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard
no Scenarios folder under DeviceGuard. Three folders listed under DeviceGuard are: default CachedDrtmAuthIndex RequireMicrosoftSignedBootChain
How do I proceed?
I have Version 10.0.22631 Build 22631 and this suggestion made a lot of applications unable to process. I resolved it by changing the value to 0 and rebooting, still had the issue, deleted the key and dword suggested above, and rebooted again. Applications are functioning normally now.
During the issues, the Windows Core Isolation continued to fail to start with no incompatible drivers listed.
I guess I should have been more specific - the Memory integrity slider is grayed out AND indicates that Memory integrity is off, so the problem is still not resolved.
The slider is gray with the message that "This setting is managed by your administrator", because you configured the registry key. The registry key overrides this control panel setting.
Since you get that message, you can know that you correctly created the key.
That the slider says it's off means that either the setting in the registry key isn't right - it needs to be set to "1", which is pretty universal for "on" - or that there's some other problem preventing it from working.
Sorry that my reply doesn't help actually fix the problem, but I wanted to let you know the gray option and message is not a problem itself, but an indicator that you made the registry change correctly. Just make sure that the value you specified is correct.
Does anyone remember the very old days when Microsoft at least pretended to give a damn about its customers? The last time I remember was when they killed Clippy in Office 2007 (2008 for Mac folks).
Hi Zadee,
I only have 2 items under \DeviceGuard, no folder Scenarios - am confused. I upgraded from Win 10 to Win 11 yesterday.
Regards
