Windows 7: My default User changed

I turned on my computer today and for some reason, my desktop had a different background and all of my icons were gone. I couldn't figure out what happened, but after a little looking I found out that for some reason, it was using the Desktop folder from a User called TEMP, instead of the one with my name on it like it usually does. How would I make my desktop use the Desktop folder in my User instead of the one in TEMP?

I'd run malwareByte in the safe-mode ... just to make sure ..

It's best to run MBam in regular mode .... just in case there is a suspicious driver lurking in the shadows. Not all load up in safe mode.

So you are running without a password.

I suggest once you get this problem fixed you start using a password on all your accounts on all the computer you use.
