hi there just wondering if someone could shed a little light on what can be stripped from my vista install, i cant seem to make a iso less that 950 meg can some just run throught what things are a must? i've look'd through the descriptions and the file sizes and there seems be be nothing with any great size left. Also is there a way of deleting the upgrade folder from the iso thats built?? i've had a little look throught the posts and the search and haven't seem'd to find what im looking for, any help would be greatly appreciated kind regards, Dene
