Windows – How to convert a vhd to a wim file

dismhyper-vpowershellwindowswindows-server-2012-r2

I just setup and sysprepped a nice new VM, now I need to convert it to a wim real quick, to upload to my sccm server. For some reason, I can't change the VM properties to boot from a legacy nic for pxe, which is how I usually capture my images using sccm. VMM just changes the settings right back, even though it says successful.

Anyway, the first page of google was terrible for this, w/ the exception of a 3rd party .ps1 script on MS's website, but I'm using 2012r2, I should be able to do this natively, right?

Absolutely, let's post a prim and proper answer for Google. This is a simple 2 command Powershell execution, using the dism module. The dism can be copied to earlier versions of Windows, provided you have the appropriate version of the windows management framework.

First, mount the vhd using

Mount-WindowsImage -ImagePath C:\VHDs\BigHomies.vhdx -Path C:\VHDMount -Index 1

Then, capture it into a wim with

New-WindowsImage -CapturePath C:\VHDMount -Name Win7Image -ImagePath C:\CapturedWIMs\Win7.wim -Description "Yet another Windows 7 Image" -Verify

And let it do it's thing. When you are done you can unmount the vhd and discard any changes using:

Dismount-WindowsImage -Path C:\VHDMount -Discard
