You don't say which OS this is, XP, Vista, Windows 7, but this might be normal.
For example, XP ships with a System Administrator account already setup. It has to do this, otherwise you would not be able to access the OS as an admin.
However, it is always recommended that users immediately create their own Admin account as a safety precaution. Once they do that, the System Administrator account disappears from normal view. That is by design.
So, there's nothing at fault there.
Is your keyboard OK? The Caps Lock key seems to be stuck on.
I LOST MY USER ACCOUNT(ADMNISTRATOR) ICON AFTER I CREATED A NEW USER ACCOUNT IN ADDITION TO ADMINISTRATOR & GUEST ACCOUNTS.
NOW THE NEW CREATED ACCOUNT WILL APPEAR WHENEVER I WANT TO LOG IN INSTEAD OF THE ADMINISTRATOR. WHEN I CHECK THE USER ACCOUNT IN THE CONTROL PANEL THE ADMINISTRATOR ACCOUNT WAS NOT DISPLAYED. ONLY THE GUEST & THE NEWLY CREATED ACCOUNT APPEAR.
SO HOW DO I RESTORE MY ADMINISTRATOR ACCOUNT? PLS HELP.
