A recent optional update for Windows 11 version 24H2, identified as KB5064081 and released on August 29, 2025, has been reported to cause significant video playback issues for users utilizing certain media applications. Microsoft has acknowledged that this update can disrupt the proper functioning of protected content on Blu-Ray discs, DVDs, and some Digital TV software.
Nature of the Issue
Users who have installed the KB5064081 update may encounter various problems when attempting to view protected media content. These issues include:
– Copyright Protection Errors: Messages indicating that the content cannot be played due to copyright restrictions.
– Playback Interruptions: Frequent pauses or stoppages during video playback.
– Video Freezing: The video may freeze at certain points, rendering it unwatchable.
– Persistent Black Screen: Instead of displaying the video, the screen remains black throughout the playback attempt.
The root cause of these problems lies in the interaction between the Enhanced Video Renderer (EVR) framework and High-bandwidth Digital Content Protection (HDCP) enforcement or Digital Rights Management (DRM) for audio. The KB5064081 update appears to have introduced a regression that disrupts the communication between media applications, graphics drivers, and the operating system’s DRM subsystem. This disruption leads to failures in playback when content protection mechanisms like HDCP are enforced.
Scope of Impact
Microsoft has confirmed that this issue affects client systems running Windows 11 version 24H2, specifically those on OS Build 26100.5074 or later. Notably, this problem does not impact Windows Server platforms. The issue is confined to local media playback applications that rely on the affected Windows components for DRM and copyright verification. Popular video streaming services remain unaffected, as they utilize different content protection mechanisms.
Microsoft’s Response and Recommendations
On September 19, 2025, Microsoft officially acknowledged the problem on its Windows health dashboard. The company is actively investigating the issue and is working on a permanent solution, which will be provided in a future Windows update. However, a specific timeline for the release of this fix has not yet been announced.
In the interim, affected users have limited options. One potential workaround is to uninstall the problematic KB5064081 update. However, this approach may not be ideal, as it could remove other non-security fixes included in the update. Users experiencing these playback issues are advised to monitor for upcoming Windows updates, as the fix will be deployed through the standard Windows Update service once it is ready. Microsoft will provide more information as its investigation progresses and a patch becomes available.
