Windows XP

One thing that happens sometimes to just about anyone, is when you forget your administrator password and you can no longer access your Windows XP/2000/2003 machine, or you just wanna hack someone else's :)

Anyhow, there are a few simple and more complicated methods to doing this.

 

 If you're an XP User, Microsoft has released a nice article about this at:

Or you can simply boot up an NTFS Driver disk and edit the password offline.

Petter Nordahl-Hagen wrote a good set of Linux-based bootdisks with NTFS support. Download this package from Offline NT Password & Registry Editor.

You may also use your own bootable floppies or CD's, as long as they have support for the NTFS file system and can run the utility you intend to use to recover the administrator password.

Note that this step is only required if your system uses NTFS as a filesystem. If your system uses a different filesystem, you must boot with drivers for that filesystem.

Other tools are out there too, but this is the one we found to be the most usefull.
