Can't Enable Memory Integrity on Windows 11?

i did a fresh install of Win 11 and i have the same problem in windows defender, the link to delete the defender reg folder doesnt work, wont let me delete the defender folder running as admin, and the other registry step doesnt have an enable for me to change it to a 1.

Note this is a clean fresh win 11 install from the online install so it must be current and there were only a few updates to get after the clean install.

I am having the same issue. I reset my PC with the latest downloaded image (22H2) and since then all of the Device Security Features have disappeared. Before the reset, all options were good and enabled and there weren't any missing requirements (TPM, virtualization etc.). Now, there is just the warning that memory integrity is disabled and nothing on the Device Security tab.

I have search and it seems like it has been happening to many other users too. There is an article about it on NeoWin too. The fix that has worked for people is to delete some updates but that only works if the issue appeared after an update was deployed. For new installs (and resets), there is no update to delete.

This appears to be a common problem: everything was working fine until the PC reset. I've seen in other forums that a newer build available through the Windows Insider Program addressed this problem. However, the standard channel build 22621.1105 released on 1/10/2023 didn't fix the error.

Thank you for the info. very helpful. After trying every trick in book from various forums I'm holding out for an update that will resolve this issue. RA

I re-enabled my Windows Insider account to validate what others posted on reddit. The preview and the beta channels had the same release in the pipeline. Installing it didn't make any difference. The same error in Device Security that Jack-96 posted at the beginning of this thread was reported. But switching to the Dev channel made a pre-release build (25272.rs_prerelease 221216.1237) available. Installing that build fixed the device security error. Now core isolation, security processor, secure boot, and data encryption are all displayed under device security with no errors.

The pre-release build is essentially a new install and it addressed the device security error. So, I tried a new custom install of the latest release 22621.1105 with deletion of the existing disk partitions. The device security is OK now. Not sure why the PC reset threw it off, but a clean OS install works as expected.

I'm having the exact same issue. Did a refresh of Windows 11 on 1-23-23 and now I'm getting the same thing you got.

No idea why a reset causes this strange error. But a clean re-install worked for me.

Thanks, glad it worked for you I reset and the also tried a clean reinstall...no luck.

Did you wipe out the partitions? I had to manually add the storage driver for the Dell XPS 9315. But it did work in the end, which leads me to believe that the issue is with Windows drivers or how they are installed during the reset.
