This issue is limited to Windows machines(not applicable to Linux computers). Windows 11 and Windows 10 laptops need to reboot after downloading updates.
A failed Windows 11 update (or Windows 10 update) will cause a computer reboots automatically in an attempt to fix the problem.

Perform a full system scan to detect and remove all malware infections. It will resolve unexpected computer restarting due to Virus infections. If the issue persists, you must check for hardware problems.
