After you install the windows xp, the default user is the name you input and the passworld is blank, unless you change them

use this nifty utility to get the passwird and user names. Ophcrack...... burn the iso to a cd and boot from the cd, it will detect your windows installation and find all password associated with accounts on the pc.
