Wel, it is time to also talk about 7, 8.0, 8.1 and 8.1 Update 1 and their Compact and Wimboot installs capabilities.
8.1 Update 1: This was the first version having native Wimboot installs capability by means of the new wof.sys driver. I ran my first Wimboot test on this OS, and by extention it is also capable to Compact Installs, wof.sys driver (new versions) is same drive used by 10 to handle Compact Installs.
All the other mentioned OSs are not capable to run natively from a Compact and Wimboot install, but this is very easily solved if during first install using WinNTSetup we select Mode: CompactNONE, WinNTSetup will take care to install the wofadk.sys driver on the new install.
How this works:
When we download WinNTSetup and extract it to a folder and then run it for the first time it request user permision to download some files from MS servers, and wofadk.sys driver is one of them, it is stored on WinNTSetup\Tools\x64\DISM folder and on WinNTSetup\Tools\x86\DISM folder to use it when required.
But at the same time (if required by the OS) it also copies the driver (x86 or x94 version as required) to Windows\System32\drivers and creates a new service on our current OS, to load the driver every boot, making the OS now capable to make Wimboot and Compact install by means of WinNTSetup.
Then this way 7, 8.0 and 8.1 will be capable to run from a Winboot or Compact install, thanks to JFX the author of WinNTSetup.
