How can I automatically turn off the PC, with the ability to cancel this action by the user?

Question

PowerShell

Good afternoon. Please tell me how to implement so that at 21.00 all PCs turn off, while so that if the user is working, then he can cancel the PC off in the pop-up window? I tried through gpo, but there is no way for the user to cancel the shutdown. The script also wrote, but only it warns that after the n-th number of minutes it will turn off, without the possibility of choice. Thank you, I apologize for the possibly stupid question.

Answer 1

Hm. Maybe try creating a shortcut on the desktop "I'm a workaholic" and using the shutdown /a command?
What's the script?

Answer 2

shutdown /f /t 60 run at 20:59
if you have time shutdown /a cancel shutdown

Answer 3

Not mine.
Copied somewhere.
I did not understand very well, corrected it for my Wishlist and - in the scheduler on the director's PC.
I'm sure you can compose it more optimally, but it's not interesting.

Answer 5

Set GPO to sleep if you do not use, say, an hour. Unless, of course, the meaning of the task is to save electricity.

Answer 6
