When using the OOBE post-Install cmd I had the problem, that I had to acknowledge the UAC messages for all installations.

Here a simple solution to this


  1. Download elevate.exe from http://code.kliu.org/misc/elevate/
  2. Add elevate.exe to WinReducerPI folder
  3. Change the OOBE script to look like this

    Code:

    @ECHO OFF
    for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%i:\sources\install.wim set CDROM=%%i:
    if not defined CDROM goto :eof
    echo Detected Installfolder on drive %CDROM%
    cd\

    @echo Administrative permissions required. Detecting permissions...
    net session >nul 2>&1
    if %errorLevel% == 0 (
     echo Success: Administrative permissions confirmed.
    ) else (
     "%CDROM%\WinReducerPI\elevate.exe" -c "%~f0"
     exit
    )

Now you only have to acknowledge teh UAC message once.
Done. Have Fun!
