microsoft has fixed a windows update Caching issue that caused driver updates to be installed on managed devices without notification, bypassing policies set to prevent automatic updates.
The issue was acknowledged on June 2 and confirmed to have been resolved in a Wednesday update to management center incident report MO1332784.
The issue affected enterprise-managed Windows devices enrolled in Intune and similar management services.
What caused the Windows Update caching error and how it affected managed devices
Microsoft explained that the issue was due to a misconfiguration in the Windows Update caching service, which temporarily deleted device enrollment information.
Without that data, affected devices were considered unregistered, preventing proper application of driver approval controls. As a result, drivers ended up being installed on devices where administrators had set policies to prevent automatic driver updates.
Microsoft updated the service cache and restored the enrollment status of affected devices to resolve the issue. Windows administrators reported having to deal with tens of thousands of devices that unexpectedly received BIOS and driver updates. In many cases, these unplanned updates caused audio or video devices to stop working.
Microsoft confirmed that the installed drivers were approved and signed by Microsoft and did not present a security risk.
However, unauthorized BIOS and driver updates in managed enterprise environments can still lead to stability, compatibility, and support issues, even if the drivers themselves are not malicious.
Microsoft has not disclosed how many organizations or regions were affected.
What affected organizations should do to resolve driver and BIOS issues
Organizations affected by the incident should check their devices for unexpected driver or BIOS updates installed between June 1 and June 4.
Devices that subsequently experience audio or video problems may require a driver rollback to restore normal operation. To do this, IT administrators can open Device Manager, right-click the affected device, select Update driver, then choose Browse my computer, followed by Let me choose and select a previous version from the list.
Microsoft has confirmed that the issue is resolved and the enrollment status of affected devices has been corrected. Policies set to prevent automatic updates should now work as expected.
A growing pattern of Windows update problems in 2026
This incident is part of an ongoing pattern of problems with Windows Update management. In April, Microsoft fixed a bug that caused systems running Windows Server 2019 and 2022 to be upgraded to Windows Server 2025 without any administrator action.
Last month, another issue was fixed where driver updates were being installed on Windows 11 devices managed by Autopatch across the European Union, again bypassing administrative policies.
Microsoft explained that it is examining how the caching service removed enrollment information to better detect, prevent, and respond to similar issues in the future.
