Info on this thread applies to VHDs and also real drives, mainly thinking on save space and portability, of course if you want to make a Compact install for every day use I recommend use Compact 4K as then the OS automatically compress any new files added to the system, and in this case after final install you can re-enabe a small pagefile if needed. It may depend of your RAM and installed programs as some of then (as Acrobat programs) require a pagefile.
I decided to start all this test using 10x64 Edu as many teachers and studends may have the possibility to activate it on the KMS service of the high school or college, then once legaly activating the first install, it is totally portable. But same applies to Enterprise if the user is working in a company having KMS service, and he is allow to do it
An option to legaly activate the Home or Pro versions could be using your MS account, but I haven't tested this option.
First I will start quoting some posts made on other threads, just to keep together all the previous comments about this subject.
Summary of my procedure.
Why wimlib is a better option than WinNTSetup when dealing with Compact installs.
Some info usefull to select your Compact mode compression.
WinSxS_reduce commands by cdob, I only use base_winsxs.cmd because winsxs_hardlink_system.cmd has created some issues in my OSs and the gain using it is very low.
Get an idea of how much space you can get back using base_winsxs.cmd to help reduce the size required for your install.
Wimb plans to add Compact install option to his fantastic tool VHD_WIMBOOT
NOTE: For 7, 8.0 and 8.1 see: http://reboot.pro/to...e-2#entry215570
well for a first post it is long enought. I will add future posts latter.
