Problems Changing/ Deleting user accounts

[hppavilion1207]

I just got a used laptop recently. when i start the computer up the old users account still shows up but it doesn't show up in the user accounts in the control panel. is it possible that there's a hidden account? if so, how do i delete it?

Is your account an administrator account?

yes

Sorry I forgot to ask, which version of win7 is this? If it's business or ultimate then you may be able to remove the account through computer management.
Either way let me know and I will have a look for you.
