If you ever find yourself locked out of your Windows XP box due to a forgotten password, and if you haven't enabled EFS, and if you have physical access to the machine, then Offline NT Password Editor will let you edit or clear away that pesky Administrator password in no time flat. I burned the CD, rebooted, and within 2 minutes I was logged in to the box.

I always knew this was possible, but I was surprised by just how easy it was.

This is probably a good time to extol the virtues of encrypting your data...
