Added user without my knowledge

[ckl2007]

I installed a new motherboard in my computer the other day and
installed windows that night when i went to reset it a few times when i
was installing software it went straight to my user and logged on i
didn't have a password set for my account. Then the next morning
before school i left my computer on while i was at school to download
something off of a friends ftp site. When i got home it was at the
switch user screen with 3 total users, 2 that didn't surprise me was
the guest account and my account then there was another account named
""xadministrator"". I tried to log onto it and it required a password,
so i tried the password that i assign to most my admin accounts and
that didn't work so i tried the generic password ""password"" and that
worked and nothing had been setup on that account. So i just logged out
and went back to my account later that night i realized that when i
pressed "ctrl+alt+delete" it came up with a error message saying ""Task
Manager has been disabled by your administrator" and then i tried using
"ctrl+alt+delete" on the xadministrator account and it did the same
thing but when i tried it on the guest account it worked perfectly fine
and task manager opened right up. I asked my father if he had done
anything to the computer since i guess maybe he'd like to know what I'm
using it for or something of the sort and he denied it. I was wondering
if anyone had any type of idea or anything and i was also wondering how
to reset the administrator rights on my computer.

You were connected to the network, with a fresh install, and you
did not, in all of that, mention that the machine did have its firewall
enabled without exceptions or that the machine had been brought
fully up-to-date on service pack and patches.
If those last two steps were not done, then quite likely something
found it and reset your install efforts back to square one (i.e. format).
PS.
Please attempt to use "." to separate sentences. Your post is quite
difficult to read due to the (lack of) grammar.

Sorry for the lack of grammar. The machine did not have a firewall
enabled but is behind a firewalled router. It is up to date on service
packs/patches. Could you tell me how i could reset the administrator
rights without doing a clean install?

Well, you may be better off than it sounded based on what
was not said in first post.
I cannot tell you how to "reset the admin rights" because
I do not really know what happened to your system.
It could be as simple as someone having walked by and
defined a new account and altered how the login is presented.
The system could of course be more heavily screwed with.
If you cannot get anyone that could have had physical access
to the system to pony up to having done something, then you
probably have to assume it was twiddled with via the network.
If it is likely clean, which of course is hard to tell, then you
could just google for windows password reset and use one
of the tools available to reset the admin account password.
But, that only establishes login capability, not reset of machine
to known valid state.
