Hi, you've done a good job writing 7Customizer. I'm saying this because few months ago i started writing my own version of vLite for Win7/Win2k8r2 (that's how it looked)and i never found enough time to finish it. The main aim of my prog was to easily remove packages without messing with DISM and command line like in this guide (By the way, i am the author of small toll called "install wim tweak" that is present in few removal guides). So far, i managed to use DISM in full GUI mode (with progress bar etc) and even to use my app without need of having WAIK installed (and i am not talking about smuggling any WAIK components somewhere). But as i mentioned, i'm not have enough time for this and is likely that i never finish my app. So, if you need any help/advice/collaboration with developing 7Customizer, PM me (i can even share some of my code)
