I updated my edition of Windows 7 Home Premium (x64) to the Windows 10 Technical Preview. After using it for a few days, I was unable to log into my regular account (Which had all of my windows 7 files) because it wouldn't show up in the log in list. It told me to instead log into my Microsoft account, so I did. It basically created a new guest account for my Microsoft account. Now when I try to log in, it will not show my first account. Here are the names

First Account: Cameron
Second Account: Cameron.Cameron-PC

I can still access some folders on my second account because it somehow is in a homegroup. So I think this means that I have to homegroup users on one computer and I can't access parts of the first account's homegroup files.

I cannot use ANY admin controls so I can't do much.

Please help me with this problem. Thanks, Cameron.
