Install-OSDeployMDT

Initializes an MDT Deployment Share for use with OSDeploy.

Property	Value
Module	OSDeploy
Platform	Windows
Requires	MDT installed, Run as Administrator

Description

Configures an MDT Deployment Share so that Invoke-OSDeployMDT runs automatically on every Update Deployment Share operation.

Without -Force, the function runs in audit mode only — it reports the current state of the deployment share without making any changes.

With -Force, the function performs the following initialization steps:

1. Resolves the MDT installation directory and active Deployment Share path.

2. Creates Templates\, Templates\winpe-drivers\, and Templates\winpe-extrafiles\ under the Deployment Share root.

3. Copies winpeshl.ini, Wimscript.ini, Unattend_PE_x64.xml, and LiteTouchPE.xml from the MDT templates directory into DEPLOYROOT\Templates\.

4. Copies Background.bmp from MDT Samples to DEPLOYROOT\Templates\background.bmp.

5. Rewrites %INSTALLDIR% references in LiteTouchPE.xml to use %DEPLOYROOT%.

6. Mirrors the <Components> element from DEPLOYROOT\Boot\LiteTouchPE_x64.xml into the template.

7. Registers Invoke-OSDeployMDT as the MDT LiteTouchPE exit command.

8. Updates Control\Settings.xml: disables x86, sets scratch space to 512 MB, sets wallpaper path.

Supports -WhatIf and -Confirm.

This function only needs to be run once per deployment share. Running it again with -Force will overwrite existing template files.

Syntax

Install-OSDeployMDT [-Force] [-WhatIf] [-Confirm]
