My wife's laptop will not run Windows Update. It tells her she must be logged on as an administrator or one of the administrator group. There is only one user account on her machine, which is an administrator account as far as I can tell, at least it is marked as such in the User Accounts screen.
I tried creating another account with admin rights and running Windows Update from that one, still didn't work.
The computer is a Compaq Presario V3000 running Windows XP Home SP3.
I attached a screen shot of the error message, hope it helps.
Any suggestions would be appreciated.
