Windows XP Administrator Password

I do not endorse products because some work well, some do not. I don't know your system or its compatibility issues. I don't know what it will do to your system but I do have one program that might work to help you get your password if all else fails. And I do not know if it's even still available. It's called "PC Wizzard 2006" at www.pcuid.com and I don't know what it costs if any.

Once loaded and installed, run it. It tells you everything you wanted to know about your system and what you don't need to know. Better than WinXP "system info". Under "configuration" click on the "locks" icon and all your passwords will be listed.

Unless some one else has a better method thats what I would do.
