A thrilling new issue has been plaguing Windows 10 versions 1809 and newer. This one causes the Local Security Authority Subsystem Service (LSASS) to fail on some devices.
Forcing users to reboot the system.
For the uninitiated, the LSASS process is tasked with enforcing security policies on a system that verifies user logon, password changes, and things like that. Failure in the LSASS.exe file is what is leads to affected users losing access to any accounts that are active on their machines.
End result? Forced reboot of said machine.
Users actually widely reported the problem after this month’s Patch Tuesday updates flew off servers. And Microsoft acknowledged the bug in the known issues section of the KB articles for impacted versions, which also includes articles for the May Update.
Microsoft has hinted that it is working on a resolution for this issue, and it intends to roll out a fix as part of the July Patch Tuesday updates that are due in a couple of weeks from now.
In short, the only workaround for this is to uninstall the June Patch Tuesday cumulative updates.
Meaning, you will have to uninstall KB4561608 (version 1809), KB4560960 (version 1903 and 1909), and KB4557957 (version 2004). And those of you who skipped the June updates and are rocking the May patches will have to uninstall KB4551853 (version 1809) and KB4556799 (versions 1903 and 1909).
And, of course, users that manually installed the fixes that Microsoft rolled out last week for the printer problems will also need to roll back those patches.
Man, what a mess!
