I too was wondering that!
AFAIK, only way to recover a lost admin password in windows 8.x is reinstallation(unless you had a back up method). But you can give a try to the registry editor steps given in the windows8forums link (given by inquirer in his first post) before you reinstall.
Both will require a Windows installation disc suiting your windows key version.
