mostly network stuff. Like it allows you to log into more stuff, it gives you more admin options. You can also log onto the Administrative acount without going into safe mode and gives you the option to use all the account types, and not just admin, and user. You get stuff like poweruser and some others.

As for Plus!. It has a few themes (basicly a few cursors, and wallpapers). It also comes with some progs like an addon to allow you to rip to MP3 in media player. It also has some other games I think. Nothign amazing. IMO it's not worth the $29. I'd go out and buy Serious Sam2.
