ATI CCC kept failing after I installed CCC8.9 (its good though)
Every time it failed I got this message, "Host Process for Windows Services stopped working and was closed"
Totally random and the message didnt say anything about CCC..
And every time it came up, I lost internet...
At first I didnt connect the two... just assumed vista was being annoying and i was having connection issues too... but then it twigged
I worked out it was CCC causing the crash and re-installed it

works fine now...
Apparently it has something to do with windows not updating windows defender propperly...
bloody M$
