Key notes

Patch Tuesdayupdates, which come only once a month, typically address multiple Windows 10 security issues. The latest such updates arrived on June 9, 2020, and delivered139 CVE fixes.

But they also left a trail of OS and app bugs, some of which affect Windows 10 users to date.

Lately, some users have been complaining about their PCs crashing on login after installing some of theJune 9, 2020 updates. Microsoft hasacknowledgedthe issue, which it attributes to the failure of the Local Security Authority Subsystem Service (LSASS) file.

The Windows 10 LSASS problem

The Windows 10 LSASS problem

LSASS is responsible for enforcingWindows 10security policy. The service verifies your credentials when you try logging into Windows, and it also handles password changes.

Considering lsass.exe is vital to the Windows 10 sign-in process, it’s going to interfere with access to your PC if it crashes. That’s the nightmare some users are facing after installing certainPatch Tuesdayupdates.

They have to reboot their PCs as a result.

The Local Security Authority Subsystem Service (LSASS) file (lsass.exe) might fail on some devices with theerror message, “A critical system process, C:\WINDOWS\system32\lsass.exe, failed with status code c0000008. The machine must now be restarted.

Microsoft has linked the bug to at least four different updates, namely:

KB4557957: This one has had otherissuesbefore, including freezing your PC.

kb4560960: It too had a couple of issues, including a now-resolved printingbug.

kb4567512: Microsoft released this optional update on June 16, 2020 to fix aprinting issue. Well, the update is now associated with the LSASS bug.

KB4567523: Also a non-security update released to fix the printer problem.

It’s a shame that there’s no ready workaround for the LSASS issue forcing users to reboot their PCs. Microsoft though said it’s developing a fix that should come out in a future update.
