here's a temporary guide:
tools required:
WAIK 1.1,
gimagex (optional),
vlite 1.2
all must be installed!
nb. this method has been tested on windows 7 build 7201 x86
Stage 1:
1) create 2 folders such as c:\s1 & c:\s2
2) copy/extract the contents of iso/disc to s1
3) mount install.wim (image 5) to s2 folder using gimagex or imagex
4) from a cmd prompt, run install_wim_tweak.exe /m & then type c:\s2
win6x_re...bin_v1.1.rar
to take ownership of reg hive, created by & credit to BM wnuku
5) commit changes & unmount
Stage 2:
1) first download this:
rem7201.zip
2) extract the batch file to the sources directory ie. c:\s1\sources
3) mount install.wim (image 5) to s2 folder using gimagex or imagex
4) run rem7201.bat from the sources directory (which has s2 folder already selected)
optional: while the batch file is running, you could delete the Recovery folder from c:\s2\windows\system32 directory, delete the contents of c:\s2\windows\winsxs\backup (you may need
unlocker as the files are locked; do not delete the backup folder itself), also delete the folders & its contents from c:\s2\windows\web\wallpaper except for the windows folder which contains the default wallpaper, again you will need the
unlocker tool)
5) once done, commit changes & unmount
then use vlite with my last session:
Last_Session.ini
before you create the iso in vlite, make sure you delete every file in the sources folder except for boot.wim & install.wim. also, you will need to extract from the original iso, setup.exe from the sources folder to c:\s1\sources otherwise you will get a cd driver not found error when trying to install!!!
i've just installed this in vmware, set my paging file to 512mb, installed vmware tools, ran windows update to install the sound driver, restarted & my hd usage space is showing up as just under 2.5gb!
nb. as the sources folder already includes dism, you do not need to download & install waik for windows 7! the bat file uses dism from the sources folder to remove the packages from windows.
