Hello,
I can report a similar pattern.
Since installing "2025-11 Security Update (KB5068861) (26200.7171)" I have had three "silent" reboots.
The only thing I can see is:
The previous system shutdown at 16:52:52 on 2025-11-15 was unexpected.
The previous system shutdown at 23:06:37 on 2025-11-14 was unexpected.
The previous system shutdown at 15:50:57 on 2025-11-14 was unexpected.
I will see if I can remove the above update to see if the PC is stable again.
Before this I have no recollection of any reboots at all.
Cheers!
Update - removed KB5068861 and my PC is stable again.
