PC automatically logs off under Windows 10 - you can do that

First open the control panel on your PC and select "Appearance and Personalization"> "Screen saver". Make sure that either no screen saver is selected or that the "Login page after reactivation" is not checked.
Also take a look at the "Energy Settings". Here you should set all options to "never" in the "Advanced Settings".
If the settings are already "Never", open the Control Panel> "Hardware and Sound"> "Power Options" again. Select "Top performance" here.
A virus may also be responsible for the PC's automatically logging off. We'll tell you what you should do in the event of a virus attack.
Check the autostart programs by opening the Task Manager with [Ctrl] + [Shift] + [Esc] and switching to the "Autostart" tab.
Make sure that there are only known programs here. Deactivate the programs that you do not know or that seem strange to you.

If you have a keyboard with a logout or shutdown button, you may have accidentally found it or the button has loose contact.
If this doesn't solve the problem, you can create a new user in Windows.
