Stdin redirection is different in powershell:

Why no simply use deviceiocontrol() instead of Native API?

BTW: Use GetCompressedFileSize() to get the compressed size.

For me is perfect now

ProductName shouldn't be important.
Wimgapi/Imagex read it from the kernel32.dll.mui, so there will be almost 40 different correct values

Well, you should use wofadk,sys not the WOF driver of windows 8.1 / windows 10.

Anyway, there is an update (KB3033929) for Windows 7 to let it understand the new signing of the driver.

for 6 and 7 it's useless because all files will be already compressed with lzx? Yes, also WIM mounting will slow down and files accessed will be extracted, so no space is saved. Will they stay compressed when changed? Does it work for newly created files? Good question, I guess it will not compress...

Hi bliblubli,

step 1 -5 sounds good. Don't really see the need for step 6 and 7.

1) Yes and they are only applied if you use unmount the WIM with the /commit option
3) Use Wimboot or compact mode if you want to save space
4) No

The wofadk driver is a part of the Windows 10 ADK. You can also use my GetWaikTools and only download Win10 DISM. If you want to use a Windows 7/8.x in compact mode you can add the wofadk.sys to \Windows\system32\drivers and import it's respected registry key Windows Registry Editor Version 5.00 [HK...

Thanks, Beta-6 works nice here. There a small problem with The Version\BUILD property on WinXP. the value of HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion, CurrentBuild is: "1.511.1 () (Obsolete data - do not use)" CurrentBuildNumber in the same key has the correct data on WinXP, 7 and...

Typical systemroot for older windows version are

\WINNT
\I386
\AMD64

Technicality windows folder can be a non top level folder like "\$windows.~bt\Windows",
but as far as I now imagex / wimgapi only support a folder direct in the root of a drive.
