Hi, TOMASO36!
Let me know if I understood your question, you want to change the Windows 10 screen timeout before it automatically shuts down, right? Well, to do this, follow the steps below:
- Go to Start , and select Settings
- Click System > Power & Sleep.
- Choose the timeouts, according to your preference.
Really hope I´ve helped!
Wish you the best,
