How can I erase this file? it seems to contain records of activities on the pc. i'm told it simply cannot be erased because its needed to run xp?
Yep, I tried this. Also recieved the same problem with Windows not recognising the profile and creating another one.is difficult to wipe the 'ntuser.dat' file of built-in accounts like the Administrator. You might be able to reassign the built-in to another privileged account with the Policy Editor. Try it and report whether it works
