Hi there I'm new to this forum and win toolkit and I've got one problem When I'm finished with my custom win7 iso it is always to large to fit on a 4.7Gb dvd. Now I want to remove the language packs (that I never use in any case), but don't know how. Can you please help me with this and if there is any other way to make my iso smaller I would appreciate it. The programs that I added (I think this is why my iso is to big) are as follows: DotNet fx 4.5 Firefox 30 Windows Live Mail DropBox WinRar WinAmp MS Office 2013 Java 7 VLC Player and some of my system drivers (Display, sound and so on) Thanks in advance
