Recovering Visual SourceSafe (VSS) Admin Password

We were given a legacy VSS repository, with passwords unknown. It turns out that not42 have created a very nice utility which wraps the hacking you have to do on um.dat to reset admin password to blank.

You can retrieve it right here:

Verified as working for me with Visual SourceSafe 6.0d (Build 9848), running XP Professional SP3.
