Hi all, thanks for all the help.

I checked the drivers. Unfortunately, I could not find out what had been installed recently, as the update history had been reset when the Creator's Update was...

I've got a windows 10 Desktop that I need help with.

Ever since around a week ago, my screen does not turn off automatically, nor does it go to sleep when I leave it for a while (like overnight)...

Thank you Kari! I'll definitely try that out.

Am I correct in assuming that a third account is created instead of simply using the dummy account, so that the original account name can be reclaimed?

Wondering if someone can help me.

I used Method 1 on a clean install of Windows 10 around when the OS was first released, and everything has been working wonderfully. Until now.
Since a few days...
