Create SysPrep VHD and VHDX for Windows Server 2012 and Windows 8


Convert-WindowsImage is the new version of WIM2VHD and it is only designed for Windows Server 2012 and Windows 8 operating system. You can use this script to create a sysprep VHD and VHDX images for the following operating system:

  • Windows Server 2012
  • Windows 8

Compare to WIM2VHD, you do not need to install WAIK.

To get started, follow below instruction:-

1. Download the powershell script from here.

2. On the Windows 8 or Windows Server 2012, copy to C:\

3. Before execute the powershell script, set your machine execution policy to remotesigned. By default script execution is disable. To  run the script, type the following command

set-executionpolicy remotesigned


4. For ease of using the utilities, open the GUI by execute the following command

.\Convert-WindowsImage.ps1 –ShowUI


Based on my testing, Working Directory and VHD name is not working in the GUI. 


  • Working Directory – The utility will dump the vhd or vhdx to C:\
  • VHD name – leave it empty (The utility will use a default name follow the SKU name). You can rename it later.

Refer to the link in step 1 and try the command line if it working. Enjoy!
