Ive read the wiki, and faq's but didnt really get an answer to my question. Ive never used MCE or even seen it going. Just how does MP integrate into XP, by that I mean does it start when I choose it to in the start menu like a regular program or does it take over XP altogether? I ask this as Ive got XP running well with all my programs etc and dont want to mess it up. Is it nessesary to make a back up of important things before you install?
