I tried Super Windows Password Reset last week when I forgot my Admin password. It helped me enter my Windows directly without losing any data. So I suggest you try this way. Here is the step by step tutorial of how to reset Windows password.
Step1, Get an accessible computer, download the Windows password reset software from
http://www.passwordreset.biz, install and run.
Step2, Burn the software onto the CD/DVD/USB
Step3, Insert the burned CD/DVD/USB into the computer that you have lost login passwords. And then following the step by step wizard to finish password recovery!
