Just wanted to say THANK YOU for such a great tool! Like others, I also had used nLite and vLite to update and customize Windows XP and Vista. I had searched the web for several hours reading various tutorials on performing a slip for Windows 7, when I came across 7Customizer. WOW! It worked perfectly the first time out of the box, no issues/problems what-so-ever. I've since installed my newly packaged Win7 ISO to a USB flash drive, and installed my customized Windows 7 Pro (x64) to my new rig. Thanks again for your work and contribution...
