WIM Witch

WIM Witch is a utility that can be used to update and modify WIM files for Windows deployment scenarios. It allows the WIM to be patched, drivers to be injected, built-in provisioned apps to be removed and .NET Framework 3.5.1 binaries to be added. It also supports the ability to inject and Autopilot configuration file into the WIM file to support Windows Autopilot for existing devices deployments.It accomplishes this by providing the user with a GUI to setup the desired configuration. Once the parameters have been configured, the image can be created or the configuration saved for use with command line functionality.

WIM Witch supports servicing Windows 10, Windows Server 2016 and 2019 images. For more information, please read the documentation about the tool in this blog post:

WIM Witch now supported on Server 2012 R2, so long as PowerShell 5 is installed.

  • Create a new image for ConfigMgr.
  • Update existing image in ConfigMgr.
  • Use ConfigMgr as the update catalog.

Bug fixes

  • Resolves another bug with importing LPs/LXPs/FODs. The target folder left out the version number, causing lookup issues during Make It So.

v2.0.0 – ConfigMgr Integration

Deploying Autopilot with MDT on USB – A WIM Witch Use Case

v1.4.0 – LP, LXP, and FOD’s

v1.3.0 – Server Support, Improved CLI, OneDrive client update

v1.0.0 – Initial Release – Core functionality

Known bugs

  • When switching from Update Existing Image to New Image on the ConfigMgr tab, the list box for DP’s is not cleared. The entries can be removed with the remove button, but it may be advisable to close WIM Witch and reload if the list box does not clear as desired.
  • The path field on the Make It So tab does not allow the user to browse for a UNC path. I’ll be working on this as the current workaround is a little hokey.
  • LP, LXP, and FOD have little to no error correction. Ensure you are importing the correct binaries
  • Source path for Features On Demand contain an extra “”. This does not cause a problem, and will be cleaned up in the future
