The usual way to hack most XP installs is to start in safe mode,
ctl-alt-del to get the password screen, use administrator with no password.
This is because most users don't actually use administrator and don'y
change the password or disable the account.

But administrator doesn't default to blank password, it inherits the
same password that the first created user is given (so if *that* was
blank you may be in luck).
