I do it seperately. First I integrate the update pack, dx9c, wga, and wmp10. After that I integrate IE7 and then seperately I use boogies installer for wmp11. After everything is updated I custimzed it to remove oobe, tour, sample sounds, setup my key, few tweaks like classic login, disable SFC, deleted catalog files, merged driver.cab and yeah that's all. In event log it says it was a "minor non fatal error" and it setuperr.log it is the only error I see. I have been using VMWARE for these because I'm trying to get close to perfect as possible I guess I'll have to try again lol
