"A limited subset of devices managed by Windows Autopatch in the European Union (EU) region might have received unexpected driver updates from Windows Update, despite administrative policies configured to restrict driver deployment," Microsoft said.
Windows Autopatch in the European Union
Microsoft acknowledged that a service-side bug caused some Windows Autopatch-managed devices in the European Union to receive driver updates that IT policies were set to block. The company described the scope as a "limited subset of devices" and said the erroneous updates came via Windows Update despite administrative restrictions intended to require manual approval for driver installation.
Impacted client Windows versions: Windows 11 23H2, 24H2, and 25H2
According to the advisory first spotted by Microsoft MVP Susan Bradley, the issue affected only a limited number of devices running client Windows platforms. Microsoft explicitly named Windows 11 25H2, Windows 11 24H2, and Windows 11 23H2 as the client platforms on which the problem occurred.
Operational effects: unexpected installs, reboots, and system failures
Microsoft said impacted devices installed recommended driver updates without user approval, even when policies required manual approval. The company added that affected systems experienced unexpected behavior ranging from reboots to, in some cases, system failures, with the severity dependent on the specific drivers that were installed.
Service-side fix and customer guidance
Microsoft reported that the bug has been addressed with a service-side fix and that customers do not have to take any action to resolve the problem. "This issue has been fixed through a service-side fix. No client-side updates or further action are required from customers," the company stated.
Related recent Microsoft update incidents
The Autopatch driver issue follows other recent update disruptions Microsoft has acknowledged. Last month, Microsoft resolved a separate known issue that caused systems running Windows Server 2019 and 2022 to upgrade to Windows Server 2025 "unexpectedly." Microsoft first acknowledged that server-upgrade issue in September 2024 after reports of servers being upgraded overnight to a Windows Server version for which administrators did not have licenses.
On the same day Microsoft confirmed the Autopatch bug was fixed, the company also said some customers are experiencing issues installing Office on Windows 365 devices because of a configuration change introduced by a recent service update.
What this means for IT administrators, technologists, and end users
- IT administrators: Policies that require manual driver approval were bypassed on a limited subset of Autopatch-managed devices in the EU; administrators will need to verify affected endpoints and review incident impacts even though Microsoft says no client-side action is required.
- Technologists and security teams: Unexpected driver installations produced reboots and, in some cases, system failures dependent on the drivers installed — teams should examine logs and driver inventory on any systems that reported instability during the affected window.
- End users and managed-device owners: Microsoft has indicated the problem is resolved via a server-side change and that no user intervention is required, but users who experienced sudden reboots or failures should report those incidents to their IT support so affected devices can be assessed.
Microsoft's short, service-side remediation closes the immediate vulnerability created by the Autopatch bug, but the company’s recent string of update- and configuration-related disruptions — from unexpected server upgrades to Office installation issues on Windows 365 — leaves administrators watching for follow-up details and confirmation that related controls are stable.
