Microsoft suggests that it finally managed to, once and for all, resolve the Defender Local Security Authority (LSA) protection off issue, which has been plaguing Windows 11 systems since March.
It is somewhat common for the Patch Tuesday OS security updates to break something, and the ones for March were no different. The updates introduced an issue with the Windows Security app wherein Microsoft Defender would wrongly report that the Local Security Authority (LSA) protection was off. It affected both Windows 11 22H2 as well as 21H2.
The company stated:
After installing „Update for Microsoft Defender Antivirus antimalware platform – KB5007651 (Version 1.0.2302.21002)“, you might receive a security notification or warning stating that „Local Security protection is off.
