I have just finished installing it. Its great my system is runnign faster than ever and i have none of those useless annoying programs clogging up my windows drive.
I fucked up the ATI cat driver integration so i had to put on the drivers manually but other than that all went smoothly.
I have removed IE with no problems but left on IE core.. just incase.
oh and the thingy whihc puts in all the CD key and whatnot is awsome. Now i can just go sit infront of the TV for 20mins and let it do all the work for me.
