Thank you so much for that detailed explanation.
I've tried the relocated folders in both win7/8 and it didn't work for me. Normal installation in win7/8 works so I guess my notebook is the problem. I've tested and now considering to just change default user folders if I want to use my ssd as cache (http://www.sevenforums.com/tutorials/18629-user-folders-change-default-location.html).
I'm perfectly comfortable with a fast boot ssd and my users\windowstemp\logs folders and pagefile relocated to HDD to reduce writes on SSD. You can't relocate ProgramData unless you don't use Windows Store. I never had a need to use system repair because I prefer other means to fix problems on my notebook. I can restore my OS within 30mins. My users folder is around 350GB.
Thanks, again, EliteBytes support for correctly understanding my inquiry and providing just the info I need! you've been a great help!
