Microsoft blames unexpected Windows driver updates on caching issue

Issue Overview
On Wednesday, Microsoft fixed an issue that caused some Windows devices to install driver updates without notice despite policies configured to prevent auto‑updates.
In an admin center incident report (MO1332784), Microsoft blamed the problem on a misconfiguration in the Windows Update caching service that temporarily dropped device enrollment information. This caused certain devices to be treated as non‑enrolled, preventing driver‑approval controls from being applied correctly.
The Intune Support Team acknowledged the issue on Twitter and Reddit, stating that the company was actively working to mitigate it.
Microsoft Response
“We’ve received a report of an issue where users’ Windows devices that have configured policies to prevent auto updates are installing drivers,” Microsoft said when it acknowledged the issue on Tuesday afternoon, June 2.
“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.”
Microsoft updated the affected service cache and the enrollment status for impacted devices. In a Wednesday update, the company confirmed that the issue had been resolved:
“We’ve validated that this issue is resolved following impact remediation confirmation from a subset of previously affected users.”
“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.”
Impact
While Microsoft has not disclosed how many regions or customers were affected, Windows admins have reported:
- Tens of thousands of devices unexpectedly receiving BIOS and driver updates.
- In many cases, audio or video devices stopped functioning after the updates.
