New Windows 11 build adds self-healing “quick machine recovery” feature

Microsoft is adding a new recovery mode to Windows to help revive crashing PCs. Called quick machine recovery (QMR), this technology enables Windows 11 PCs to boot into the Windows Recovery Environment (WinRE, also used by Windows install media and IT shops for various recovery and diagnostic purposes), connect to the Internet, and download Microsoft-provided fixes for "widespread boot issues" that could be keeping the PC from booting properly.

Initially announced in late 2024 as part of the "Windows Resiliency Initiative," QMR is one of a couple of steps that Microsoft is taking to prevent a repeat of mid-2024's CrowdStrike outage, when a bugged update to one of CrowdStrike's security products brought down millions of Windows PCs and servers and caused widespread service outages in many industries. Fixing some of those PCs required booting and fixing each one individually; QMR should make it possible to apply that kind of fix remotely even if a PC is so broken that it can't boot into Windows proper.

The initial version of the QMR feature is rolling out to Windows 11 PCs enrolled in the Canary channel of Microsoft's Windows Insider testing program. This is the least stable and most experimental of the four Windows 11 testing channels. As Microsoft adds features and fixes bugs, it should gradually move to the Dev, Beta, and Release Preview channels before rolling out to the Windows user base more broadly.
