I normally finish the work day by putting my PC on Lock (Win key + L) so that I can leave all my documents and applications open. More and more often lately, I come back to the PC in the morning only to find that, after I log back in, the OS seems to have restarted, meaning all my apps and documents have to be reopened all over again.
This happens without any warnings or prompts having appeared the previous day.
Needless to say, this is very frustrating, and even more frustrating is to see that previous reports of this behaviour from other users ellicit no helpful response from Microsoft.
My PC is running Windows 10, which I've set up (under Windows Update's Advanced Options) to have the system defer upgrades. Furthermore, it reboots even if there are no pending upgades. My PowerPlan options has the "Turn off hard disk after"option set to 'never'.
Any suggestions how to prevent this very unintelligent and annoying feature of Windows 10 would be appreciated.
