Well, how about this: I own xp media center and xp pro, both from the same shop. i'm using mce and i put the pro version on my cousin's pc. i haven't got any problems with my pc but got a call a few days ago from my cousin to tell me about wga which is bugging him every start-up. remember: PAID copy of win xp pro, bought from a serious computer shop, in its box, watermarked cd!!!!! HA! I tend to agree now with |-|ackers and [rackers (sorry mods, please remove if offensive). Get a life, M$ people. I bought my pc, paid for it so NO-ONE owns my pc but me and only me. And if I'll ever run into my cousin's trouble, it will probably be bye bye blue, red, green and yellow and welcome penguin! That said, I rest my case...
