IT administrators running Windows Server 2025 can now use quick machine recovery on the operating system once they install the October 2026 security update, Microsoft announced.
Quick machine recovery, or QMR, is built to let administrators repair serious boot failures through targeted Windows Update fixes, without needing physical access to the affected machines. When a device will not start because of a configuration change or a new driver, QMR boots into the Windows Recovery Environment and launches the QMR Tool. The tool then sends crash data to Microsoft, which can remotely adjust settings or remove problematic drivers or updates to resolve the problem.
In a message center update, Microsoft said the October 2026 security update extends quick machine recovery to Windows Server 2025. The company described the feature as a way to help restore devices hit by widespread boot issues, using WinRE to search Windows Update for applicable remediations.
On Windows Server 2025, cloud remediation is turned off by default. Administrators can enable it through Group Policy under Computer Configuration, Administrative Templates, System, Quick Machine Recovery, which allows the server to retrieve and apply cloud-sourced remediation. For local configuration, an administrator must sign in to the target server with administrator permissions and use the Local Group Policy Editor. In domain environments, administrators can use Group Policy Management on a Windows Server or an administration computer, but they also need permission to edit the GPO and link it to the intended organizational unit.
To turn QMR off through Group Policy, administrators must explicitly disable Enable Cloud Remediation to block cloud-sourced remediation and disable Enable Auto Remediation to stop automatic application of local remediation packages.
Microsoft introduced quick machine recovery in November 2024 as part of its Windows Resiliency Initiative at Ignite 2024, responding to a July 2024 outage caused by a faulty CrowdStrike Falcon update that left millions of Windows devices unable to boot. The company began testing the feature in late March 2025, rolling it out to Windows Insiders in the Beta Channel. In November, it also began testing a faster version that runs a single scan to fix systems with boot problems rather than looping through solutions.
