Out of curiosity I tried the MS three step on a portable that is used as part of a ethernet and wireless network in a dental office. After I installed it, the network disappeared on the portable. I couldn't see the hard drives on any of the other machines and I couldn't see the network printer that is on it's own print server. I restored XP to the state immediately before the MS installation and everything was fine.
As far as I can tell, you install the thing and that's it. There are no options. It was real scary.
