How do I keep Windows 8 from logging me out all the time?

It is logging you out because there is something on your Surface that is appearing to be a security lapse.  That could be anything from having an Exchange email account, or being part of a homegroup, or something else.  And, once the system detects this, and puts in the security measure of logging you out, there is no access to a setting to undo that.

I had the same problem, but I found a solution.  You need to refresh your PC.  Go to PC settings -> Update and recovery -> Recovery -> Refresh your PC without affecting your files.

This will reset all of the settings that you cannot see, and when the PC is done, and reboots, it should not log you out anymore.

If that doesn't work, then try the more drastic Remove everything and reinstall Windows option.  It's kind of the nuclear option, but it will work if the previous option did not.

I have the same problem with being logged out if I leave the computer for just a second.  It is annoying having to constantly input my pin number.  I tried the same solution, but there is no RESET SECURITY POLICIES offered when I go to User Accounts.  Any other suggestions?  Thanks.

When I leave the computer alone for a minute, the screen times out and returns to the login screen where I then need  to reenter the password. It happens so often that I stop using the computer all together because it has become too much of an annoyance. I do not want my screen to lock unless I decide to lock the computer on my own. Is there a feature that disables the computer from going into the lock mode?

Thanks Michal.
