Windows 10: Signing in with Temporary Profile

I just purchased a Surface Laptop 2 and was working perfectly fine for the first week and now every time that I sign in it tells me there was a problem with logging me in and says I need to sign out and sign back in. When I do that I just continue to get the same message. So, instead of signing in I just close the message and then I get a notification that I was signed in with a temporary profile. Nothing that I do from there will stay. Any programs I install or any files I save will be gone when I log out and log back in. Not sure what to do at this point.

PC switched me to a temporary user profile


It'll be the same tutorial below, but do the steps while signed in to your built-in Administrator account.

Fix You've been signed in with a temporary profile in Windows 10  


Morning

Got exactly this problem. To start with it was named correctly, so I went thru the steps described above. Then it was named incorrectly so I went through those steps. Now it just keeps generating new temporary profiles (scrolling up through numbers each time). I've included some pics below. vickerse is the right username.

Serves me right for doing software updates :/. It did load initially after the updates tho.

All advice appreciated! Please and thank you.

 

W10 Signed on with temporary profile

PC booted up signed on with a temporary profile about a week ago.

After trying various solutions suggested on WEB without success including using the official Microsoft repair utility I resorted to the suggestions regarding editing the registry.

This did work perfectly apparently for the first or so boot afterwards but the machine constantly returns to the temporary profile.

So what exactly is going on (malware/trojan/boot sector malware or some other software/corruption issue?
