Some users' Windows devices with policies configured to prevent auto updates may be installing drivers

Title: Some users' Windows devices with policies configured to prevent auto updates may be installing drivers User impact: Users' Windows devices with configured policies to prevent auto updates might have been installing drivers. More info: As we worked to remediate the impact, we determined that the drivers installed were Microsoft approved/signed and that they didn't pose a security threat. Final status: We've validated that this issue is resolved following impact remediation confirmation from a subset of previously affected users. Scope of impact: This issue may have caused drivers to be installed for users with a Windows device configured to prevent auto updates. Start time: Tuesday, June 02, 2026, at 1:00 PM UTC End time: Wednesday, June 03, 2026, at 5:30 AM UTC 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. Next steps: - We're continuing to review how this caching service temporarily dropped Windows device enrollment information to better inform how to detect, prevent, and respond to similar service issues in the future. This is the final update for the event.
