I'm wondering the same thing. The download had 20-25 different utorrent.exe's with different features.
I opened a random one. A reply to my post about being banned on the forums i got the utorrent from leads me to believe I opened the Stealth mode one. Probably some sorta instant detection there. Also says you can get banned because your upload goes crazy high... but i didnt even give it enough time for that to happen
