Microsoft issued an out-of-band update for a printing issue that was introduced via this month's Patch Tuesday updates for Windows 10, but now the software giant confirms another outstanding issue. This bug isn't caused by the cumulative updates that were rolled out on June 9 for various Windows 10 versions, they seem related to the May 2020 Patch Tuesday fixes that were rolled out last month. These patches can apparently cause crashes of Local Security Authority Subsystem Service (LSASS):
More specifically, the company says that after you install the May and June 2020 update, there’s a chance that the Local Security Authority Subsystem Service, also known as LSASS, could fail on some devices, eventually forcing a reboot of the computer.

The error that the impacted devices would get is the following:

“A critical system process, C:WINDOWSsystem32lsass.exe, failed with status code c0000008. The machine must now be restarted.”
Microsoft is working on a fix. The bug can be prevented by avoiding the shutdown feature, and using sleep mode instead.
