A friend of mine recently inquired about how he could gain access to an old Windows server he had running, for forgot the admin password. I pointed him towards this software, which I have successfully used in the past.

There is a new version since the last I checked that now supports Vista, and more disk controllers. I was starting to run into some newer laptops from HP with SATA controllers, which did not have drivers included on the password reset disk. Hopefully this new version will have those drivers.
