Microsoft announced that it will retire Microsoft Support Diagnostic Tool troubleshooters in future versions of Windows, with MSDT ultimately being removed in 2025.
Also known as legacy inbox troubleshooters, these Windows built-in tools are used to diagnose and fix issues affecting some Windows features automatically.
While the MSDT app that runs them will be retired in 2025, the troubleshooters will be killed off with the launch of the next Windows 11 release.
You can access the Get Help troubleshooters from Windows Settings by going to Start > Settings > System > Troubleshoot > Other Troubleshooters and selecting the troubleshooter that would help you address your issues.
"If you're running Windows 11 version 22H2 and older, Windows 10, Windows 8.1, Windows 7 or any other earlier OS version, your device will not be affected by the MSDT Troubleshooter retirement," Microsoft added.
While Redmond doesn't explain the reasons behind deprecating MSDT in future Windows versions, a possible explanation would be MSDT vulnerabilities patched by Microsoft in 2022 after they were exploited in the wild using zero-day exploits.
