This tutorial will show you how to use Quick Machine Recovery test mode in Windows 11.

Quick machine recovery is a feature that enables the recovery of Windows devices when they encounter critical errors that prevent them from booting. QMR automatically detects, diagnoses, and remediates boot critical issues from WinRE, helping restore productivity without requiring hands on, in-person intervention. This feature can automatically search for remediations in the cloud and recover from widespread boot failures, significantly reducing the burden on IT administrators when multiple devices are affected.

Building on the foundation of Startup Repair, quick machine recovery uses a secure and connected Windows Recovery Environment to scan Windows Update for remediation options. This allows devices to be recovered without requiring manual intervention.

Quick machine recovery offers a test mode, providing a controlled, simulated environment for you to validate your configurations and the auto remediation process without triggering an actual system failure. Test mode allows you to verify that the recovery experience functions as expected before deployment to production systems.

Starting with Windows 11 build 26200.5518 (Dev 24H2) and build 26120.3653 (Beta 24H2), as a follow up to the last announcement of quick machine recovery, the test remediation package is now available for Windows Insiders to experience the full capabilities of QMR in action. Microsoft encourages Windows Insiders to test it today. The remediation package “Quick machine recovery update for Windows 11” will be automatically installed by QMR when “test mode” is activated. To verify the quick machine recovery remediation is installed, go to Settings > Windows Update > Update history. The remediation should be listed under Quality updates. Please note that the ability to see the remediation package in your Windows Update history is gradually rolling out so not everyone will see this listed there right away. To provide feedback, simply open the Feedback Hub app on your Windows device, navigate to Recovery and Uninstall > Quick Machine Recovery, and share your insights. Stay tuned for further updates and enhancements as Microsoft continues to improve the resilience and reliability of Windows.

Starting with Windows 11 build 26100.7309 (24H2) and build 26200.7309 (25H2), Microsoft is updating Quick Machine Recovery in Windows – Microsoft Support make getting back to a working PC clearer and faster. The experience in both Windows Settings and the Windows Recovery Environment (WinRE) has been streamlined so options are easier to find and use. On PCs with the settings “quick machine recovery” and “automatically check for solutions” both enabled, QMR now runs a one‑time scan by default instead of repeating scans in a loop. If a fix isn’t available right away, you won’t be left waiting; QMR will quickly point you to the most appropriate recovery options to get you back up and running.

4 Restart the computer to start test mode.

5 The system will now start test mode and go through autoremediation of a simulated crash and reboots back to Windows. (see screenshots below)

If after reboot the device goes into Windows RE instead of starting test mode, follow these steps:

1) In Windows RE, select Continue to boot Windows normally.

2) In Windows, execute the two commands:

reagentc.exe /Disable

reagentc.exe /Enable

3) Retry the quick machine recovery simulation starting from step 1
