Microsoft has officially acknowledged that recent security updates for Windows 11 are causing the “Reset this PC” (Push-button reset) recovery feature to fail.
The issue was confirmed in the release notes for the March 2026 hotpatch updates, affecting systems running the latest operating system version.
The problem stems from the March 10, 2026, Hotpatch KB5079420, which updates Windows to OS Builds 26200.7979 and 26100.7979.
This hotpatch was initially deployed to deliver miscellaneous security enhancements to internal operating system functionality without requiring a full system reboot.
Windows 11 Updates Break Push Button Reset
However, Microsoft has added a formally known issue to the release documentation, warning administrators that “Reset this PC might fail with the March 2026 Hotpatch security update or later“.
The “Reset this PC” functionality is a critical system recovery tool that repairs the operating system while preserving user data and essential customizations.
When this feature breaks, users attempting to restore their systems to a default state or recover from severe software corruption may find their devices unable to complete the process.
This failure can temporarily trap a device in a malfunctioning state if the user does not have alternative recovery tools prepared.
In addition to the recovery feature breakage, the same KB5079420 update introduces another confirmed bug: signing in with a Microsoft account may fail in applications like Microsoft Teams Free.
The documented issues are specifically tied to the recent hotpatch servicing updates for enterprise and supported clients.
The primary affected operating systems include: Windows 11, version 25H2, Windows 11, version 24H2.
Devices running these versions that have installed the March 10, 2026, update or subsequent patches (such as the March 13, 2026, KB5084597 update) may experience these recovery environment failures.
Currently, Microsoft has not provided an official automated fix for the Push-button reset failure in the immediate out-of-band updates.
Administrators and users encountering this issue should consider alternative recovery methods until a formal resolution is deployed.
When the built-in Windows Recovery Environment (WinRE) fails, IT professionals can temporarily work around the issue by using external recovery media.
Booting the device directly from a USB recovery drive or an official Windows 11 installation media allows administrators to perform a bare-metal recovery or reinstall the operating system without relying on the broken internal reset mechanism.
Additionally, administrators can manually verify the status of the Windows Recovery Environment in an elevated command prompt.
Running reagentc /enable can sometimes repair a disconnected recovery environment. However, this standard troubleshooting step may not bypass the specific registry or system file conflicts introduced by the KB5079420 patch.
Organizations utilizing Windows 11 24H2 and 25H2 in enterprise environments should temporarily pause reliance on automated system resets.
Security and IT teams are advised to rely on centralized backup solutions or endpoint imaging tools until Microsoft restores the core internal recovery functionality in a future cumulative update.
