Microsoft Deployment Toolkit
Microsoft Deployment Toolkit (MDT) is a legacy framework for automating Windows OS deployment. OSDeploy integrates with MDT via the OSDeployMDT module to support existing MDT-based deployment workflows.
Microsoft Deployment Toolkit has been officially retired by Microsoft. Install it only if you have an existing MDT-based workflow that requires it.
MDT provides a framework for creating deployment shares, task sequences, and automated OS installs. It was the dominant Windows deployment tool before cloud-based solutions and Microsoft Intune became mainstream. The final release (6.3.8456.1000) remains functional on current Windows versions but receives no further updates from Microsoft.
OSDeploy's OSDeployMDT integration targets shops that already run MDT deployment shares and want to extend or automate them with PowerShell without rebuilding their entire deployment infrastructure.
Why OSDeploy Requires MDT
Install-OSDeployMDT configures and extends an existing MDT deployment share
Invoke-OSDeployMDT runs automatically as the MDT LiteTouchPE exit script on every Update Deployment Share
MDT's Microsoft.BDD.TaskSequencer COM objects are used for task sequence orchestration
Required only for MDT integration features — not needed for standalone WinPE or OSDCloud deployments
If you are starting a new deployment workflow, use OSDCloud instead of MDT. MDT integration in OSDeploy exists to support existing environments.
