"Administrator" is a built in account, you did not create it, XP installation comes with it. You can change its name after installation but most people don't bother. Wether SAM which is the account you created has the adminisrator's rights is an other concept, but understand that SAM is not the administrator account. In MS's view, people are not supposed to use the Adminisrator account as a normal user's account but only for computer administration, that's why they let you create a new account during installation. That first account does have administrative rights. A 3rd problem is taking ownership of the files that were created before the reinstallation as I guess most your problems come from that. Did you do it yet or did you just read the article and get stuck (this is not very clear from your post) ? Do you mean they did not appear in "My Documents" or you could not open your files ?
