TL;DR
Microsoft has immediately retired the Microsoft Deployment Toolkit (MDT), ending official fixes, updates, security patches and support. The company suggested customers use Windows Autopilot or Configuration Manager OSD as alternatives; Microsoft has not publicly explained the sudden immediate retirement.
What happened
Microsoft announced an immediate end to the Microsoft Deployment Toolkit (MDT), a free suite of tools used to deploy Windows and applications. With the retirement effective at once, Microsoft said there will be no further fixes, updates, security patches or product support, and warned that MDT download packages could be removed or deprecated from official channels. While existing MDT deployments are expected to keep functioning for the near term, the vendor said it will not provide future compatibility updates for upcoming Windows releases. Microsoft first placed MDT on a deprecation list in December 2024, and many organizations had already begun moving away. The company has not given a public reason for the abrupt retirement; social media users offered theories including unpatched security issues and strategic preference for cloud-first deployment tools. Microsoft recommends Windows Autopilot or Configuration Manager Operating System Deployment (OSD) for customers seeking replacements.
Why it matters
- Administrators relying on MDT will need to migrate or accept unsupported deployments without future patches.
- No security fixes or updates are forthcoming, which could increase exposure if vulnerabilities are found.
- Future Windows releases will not receive guaranteed compatibility updates through MDT.
- Recommended alternatives (Autopilot, Configuration Manager OSD) may require different infrastructure or operational changes.
