It's freely redistributable. Makes its own sauce. I write a RunOnce registry key in case it forces a reboot to restart the install, and delete the key if it doesn't force a reboot.

But what are you going to use to write a registry key? My point is, all the stuff you need to do this kind of thing (the Setup API) has to be extracted/installed itself before it can be used- chicken and egg.
