Thanks Varun,
Unfortunately it didn't work : (
You see, when I first turn on the pc and it loads Win2k, it welcomes me with a little window to enter your username and passw. By clicking in the drop down list of users I can see that there are 9 users previously registered. The way I get into the system is by double clicking enter (my friend told me this). Except that once I'm in this way, and I do what you told me, I can only see "Administrator" and "Guest" as users. Where are the other 9?
