edit:
The programmer's english may not be great but his code performs just fine. In the executable there are recommended settings (what i set mine to), and if something breaks he has the Win XP defaults for each option hard coded. So it is possible to reset things back to their original state.

Oh, and I also noticed that Norton AV 2k2 didn't seem to want to install after I had turned some scripting function off from XP-AntiSpy. turned it back on, installed NAV, and then turned it off again, worked fine.
