Microsoft’s latest Windows 11 update is causing significant problems for users trying to play protected video content.

The most severely affected applications are those handling Digital TV broadcasts and BluRay or DVD content.

Users attempting to watch protected media through these platforms are experiencing copyright protection errors that prevent normal playback.

The issue specifically targets applications that rely on Enhanced Video Renderer technology combined with HDCP enforcement protocols.

Applications utilizing Digital Rights Management for digital audio content are also experiencing widespread disruptions.

Users report frequent interruptions during playback, complete system freezing, and persistent black screen issues that render their entertainment systems unusable.

Technical Root Cause Identified

The problem stems from conflicts between the update’s security enhancements and existing copyright protection mechanisms.

Microsoft’s August preview update appears to have modified how Windows handles protected content streams, creating incompatibilities with established DRM systems that many media applications depend upon.

The Enhanced Video Renderer, which manages high-quality video output on Windows systems, is failing to communicate with HDCP enforcement protocols properly.

This breakdown in communication triggers copyright protection errors that immediately halt video playback, even for legitimately purchased content.

Importantly, popular streaming platforms like Netflix, Amazon Prime Video, and Disney+ continue operating normally.

The issue exclusively impacts local media playback applications and broadcast television software, suggesting the problem lies specifically with how Windows processes locally stored or broadcast protected content rather than web-based streaming protocols.

Microsoft officially acknowledged the issue on September 19, 2025, confirming that the KB5064081 update and subsequent releases contain the problematic code.

The company’s initial response came nearly three weeks after users began reporting widespread playback failures across various forums and support channels.

Currently, Microsoft is developing fixes for future Windows updates but has not provided a specific timeline for resolution.

The company has not offered temporary workarounds or rollback recommendations for affected users, leaving many without access to their purchased digital media collections.

Windows 11 version 24H2 users should avoid installing KB5064081 if possible until Microsoft releases a corrective patch.

Those who have already installed the update may need to pause automatic updates to prevent additional complications while awaiting the official fix.
