This month's Patch Tuesday Windows 10 update has managed to bring in quite a few issues, including some that have now been acknowledged by Microsoft. After releasing an out-of-band fix for the printing issue, the Windows maker has now confirmed that some users might experience crashes due to a failure in the Local Security Authority Subsystem Service (LSASS) file, lsass.exe.

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