I spent almost one month with reading this forum and trying to make custom lighted version Windows 7 x64. There are a lot of threads and topics about this problems but guides and advices are often incomplete, wrong and nonfunctional in my case. And what is more a lot of these guides using vLite and 3 different version of WAIK because vLite is old and crappy peace of software now. Also there are tons of customized .bat and .inf files and it seems to me that everybody has to have his own original procedure of setup. Well shortly chaos... So I would like very briefly describe easy method how one can make EASY fully functional updated and streamlined version of Windows 7 x64. What you will need: RT Se7en Lite http://www.rt7lite.com/ Windows 7 Toolkit http://www.wincert.net/forum/index.php?/files/file/5-windows-7-toolkit/ Rt7-Booster (WinterStorm 2050) http://www.rtwincustomize.net/web/index.php?/topic/8953-rt7-booster/ Untouched MS Windows 7 - en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso SoLoR Updates -- or Microsoft Update Catalog Configuration file for RT7 Lite http://www.rtwincustomize.net/web/index.php?/topic/7146-components-to-keep/ 1. Use RT Se7en Lite to ONLY integrate SoLoR Updates 2. Run Windows 7 Toolkit and choose Component Removal (DISM procedure) and delete packages (I deleted all packages except red ones=critical, local printer service and .net 3.5.1; name and description of packages is (in Windows 7 Toolkit) sufficient to decide individually) 3. Start RT Se7en Lite with Configuration file for RT7 Lite and add your additional tweaks etc. 4. Use Rt7-Booster and select only modules which correspond with removed components from step 3; in the case of untouched Configuration file for RT7 Lite you should use all modules (you can also integrate IE 9 and delete content of WinSxs folder here) 5. Your lighted Win 7 x64 are finished. Final ISO file should has 1.3-1.8 GB according to used updates and removed components Actually I removed some additional components (in comparsion with default Configuration file for RT7 Lite) according to WinterStorm 2050 guide and I have fully functional Win 7 for games, wifi and cable Internet and also for work. I have found out only two problems. It is not possible to install Rosetta Stone software because it depends on running Windows Firewall service (during installation only). And also if you completely remove Windows Media Player and codecs (with Windows 7 Toolkit) it would not be possible to install some programs required WMP. Usually some encyclopedias or learning software. So be there careful. You can still run such a software in a virtual machine. You can get down some more MBs deleting unnecessary files while Windows is mounted. Just find this file somewhere at this forum "batch7x64sp1.bat" :-).
