Need Advice, or help on Skype making custom Win7 usb installer

[YourNumbr1Fan]

Hi my VC friends!

So I want to make a custom Win7 Ultimate x64 usb installer......slip-streamed with all of my drivers, all important updates up until the present time (all but IE10, which I don't want because the Silverlight plugin doesn't work correctly with API, and my wife's connection to her job's Intranet, or a certain section, doesn't work with the IE10 version), custom settings, pre-patched for custom themes, a few softwares installed (like VLC, K-lite mega codec pack, etc.)........

I have 2 programs downloaded and installed: RT7 Lite, and Windows Updates Downloader.
I have my Win7 Ultimate disk.

Last night I fooled with it, extracted my disk with RT7, loaded all the .inf driver files from my system, and then was building the usb...the RT7 prgram says it could take from "60-to-90" minutes, but god! it went into over 2 hours!, then I started thinking that maybe I was doing something wrong, and quit the program. That left me having to spend hours trying to delete all the temporary files from the operation that RT7 puts in the Temp directory "C:\Users\YN1F\AppData\Local\Temp", which was a MAJOR hassle! I finally managed after doing it from Safe Mode (taking ownership of the files, then using East Tec Eraser).

I'm just wondering if any of you have done this before, built a custom Win7 install with RT7, and, I'm hoping perhaps someone could jump on Skype with me and help me try it again......

Thanks ahead of time! I'll keep checking here for any comments throughout the evening.
