I now have inherited 300 windows test machines @ work and these tools are really invaluable. Psexec from the pstools package is very cool. It lets you exec somethiing on a remote windoze box with out having to install anything on the target system. And pslist is the best text process list I've seen so far. None of these are really music releated but they are helpfull. Sysinternals has some of the best utils.
