Logged in as temporary user

ran a repair on a computer that ran into some trouble with booting after a recent power out
the ntoskrnl.exe file was corrupt so I copy/pasted it from a windows 7 dvd after trying startup repair several and setting the proper disk(s) as active.

the "system" partition appeared to be empty just so you know.

Now the system starts just as it should with one problem. I'm only getting logged in as a temporary user, even after creating a new administrator account and while booting into safe mode.

EDIT: I also notice that under windows activation it says status not available... why might this be? It was fully activated and the like about a week ago. The computer is running much slower than normal as well.

This happened during a repair install.
Clean install wasn't possible.
Turns out the HDD was on it's way out. File after file was becoming corrupted.
Turns out the person who brought me the computer had it directly next to their Subwoofer... put simply "user error" lol

not as good as refrigerator magnets on the side of people's towers... seen that before
