Issue Status: ONGOING

Issue Description: Some users’ Windows devices with policies configured to prevent auto updates may be installing drivers.

More info: As we work to remediate the impact, we’ve determined that the drivers being installed are Microsoft approved/signed and that they don’t pose a security threat.

Current Update: 03/06/2026 09:01:00 AM – Microsoft has confirmed that a caching service used by the Windows Update service temporarily dropped device enrollment information. As a result, affected Windows devices were briefly treated as non-enrolled, preventing the expected driver-approval controls being applied. They are updating the affected service cache and the enrollment status for affected devices to remediate the impact and anticipate this process may complete by their next scheduled update, at which point they will monitor to confirm full remediation.

Scope of impact: This issue may cause drivers to be installed for users with a Windows device configured to prevent auto updates.

Root cause: A caching service used by the Windows Update service temporarily dropped device enrollment information. As a result, affected Windows devices were briefly treated as non-enrolled, preventing the expected driver-approval controls being applied.
