WinXP locks all account info except the one you have logged into.
As administrator you can create a new account and modify how windows operates, you still can not access someones user account. You need to be logged in under that account to access any of the info: Favorites,My documents, etc...
You need to log into your account and then transfer.
I am logged in through my user account with admin rights but I cannot open Windows easy transfer due to it saying I am logged in with a temporary profile, whatever that is! I am using XP home premium, don't know if that makes a difference.
