User accounts

Windows 7 Pro x64: I “had” 2 user accounts. One is me with admin permissions the other is my “iPad” user.They have different copies of iTunes. It’s easier to keep 2 different devices with different content this way.
Had a major issue with Office last month, ended up having it worked on at a local shop. They almost had to completely reinstall office along with some system work that was causing the errorss.. My problem now is at the logon screen I have 2 users, one is my admin account the other is called “other user”, which is pass worded ( I am not able access this account.) This account also does not appear in the control panel in theconfigure users section. My iPad user shows up on the control section but does not show up on the logon screen. Should I even attempt to fix this or just start all over? How would I get rid of the “other user” account that doesn’t show up on the control screen? I’m really frazzled here.
As always, any comments or flames welcome.
Tnx
