Recently I purchased and set up a computer for my Grandad then delivered it to his house which is 250 miles away! The PC is almost new so is running Windows XP SP2, complete with all Windows updates up to a few days ago. As he lives alone I set it up without setting up any user accounts other that the default 'Owner' account. Somehow after a week or so's use, and I have no idea how this could have happened, he has managed to set up 2 user accounts (in my name and his, he was assuming I had set it up using one of our names). He says he was asked to enter the account names duing the boot up process, and says he remembers something about files being copied as part of this process. Now when he logs in using either of the accounts he cannot see the software/settings I installed for him. My question is: How do we get back to the original 'Owner' account (it's not available on the log-on screen)?
Not sure what you mean by 'Owner' account. You should have an account showing as Adminstrator and one as Guestby default. If you are worried about deleting the accounts you want to get rid of. Try changing the accounts to Limited and then turn them off. That way they will still be available to restore to Administrator should the whole procedure prove not to achieve what you require. If the computer runs OK you can then delete them
