Elyse Betters Picaro / ZDNETHave you ever run into trouble trying to boot up your Windows PC? Boot-up errors are among the most challenging to troubleshoot and fix. Now, Microsoft is launching a new tool that will step in when your computer refuses to boot properly.Also: Microsoft just blocked this popular Windows 11 local account trick – but workarounds remainKnown as Quick Machine Recovery, or QMR, this feature is ready for testing in the latest Windows 11 Insider build. Though Microsoft touts it as a tool for IT administrators, it is also available for home use, where it is turned on by default. How it worksThe Windows Recovery Environment, or WinRE, is a dedicated recovery partition on your computer that attempts to repair boot-up problems. Normally, you might have to trigger WinRE manually, but with QMR, the process is designed to be more automatic. When a critical boot-up problem occurs, your PC will enter WinRE mode, connect to your network, and then send diagnostic data to Microsoft. Based on that data, a specific fix for the issue is sent to your PC via Windows Update. If the fix is successful, your PC should then be able to boot without further trouble. Also: 6 things I always do after setting up Windows 11 – and why you should tooOne key benefit is that the recovery process is designed to run automatically and even remotely. In an organization, IT administrators can send targeted fixes to problematic PCs without requiring physical access. For a home user, the fixes are managed by Microsoft. In either scenario, you do not have to spend time manually diagnosing or trying to resolve the glitch. QMR is part of the Windows Resiliency Initiative that Microsoft announced last November at Ignite 2024. The company is asking IT staffers and other Windows Insiders to start testing the new feature and provide their feedback through the Feedback Hub built into Windows. Insiders should also expect a test remediation package over the next few days, which will let them see how QMR performs. More
