Who's in charge ?
I finished a session on my Windows 11 PC late last night and clicked the 'Shut-down' icon. I saw the screen go off and started preparing for bed. I then noticed the PC had restarted itself and wanted me to log-in.
I entered my PIN and watched it start up and again clicked the 'Shut-down' button. A few minutes later it restarted itself and wanted me to log-in again. For the third time I went through the shut-down procedure but it would not stay shut down so I switched off it's electricity supply and went to bed.
This morning I switched on and Windows stated that it had not been shut down correctly and dumped a large log file somewhere in the system. Eventually it started and a Windows update named 'Stack Package' commenced. Apparently this is usually a background update and might have been running when I wanted to switch off last night. I've run the Scannow utility which found and repaired a number of system files.
The PC is running ok at the moment and I think I'm in charge ....
