How can I change or erase the Windows XP password from Ubuntu Live (11.04) booted on the PC in question?

I reckon it should be possible, at least it is possible to do so to another Ubuntu installation, but I never knew how to do it to Windows XP.

not really, I am looking for ways to do this from nix by accessing the hdd and erasing/modifying the necessary files, which I can do, the question is which files – Richard Rodriguez May 1 '11 at 22:18

FYI - No chance of changing the password - unless you think in MD4 hashes. – new123456 May 2 '11 at 10:40

In Fedora I used chntpw to wipe out the Windows administrator password. For example:

chntpw -i /media/WindowsXP/WINDOWS/system32/config/SAM
