Windows 11 24H2 KB5064081 Update Causes Video Playback Issues

The Windows 11 24H2 update KB5064081, released on 29 August 2025, has disrupted video playback for protected content across several applications, causing black screens, freezes and interruptions, particularly for Digital TV broadcasts and BluRay or DVD content. The fault appears to lie in conflicts between the update’s security enhancements and existing protection mechanisms, with the Enhanced Video Renderer failing to communicate properly with HDCP enforcement during local media playback.

Netflix, Amazon Prime Video and Disney+ are reported to continue operating normally, suggesting the issue is confined to locally stored or broadcast protected content rather than web-based streaming. Microsoft officially acknowledged the problem on 19 September 2025, and said fixes are being developed for future Windows updates, though no specific timeline or rollback guidance has been provided.

Users running Windows 11 version 24H2 are advised to avoid installing KB5064081 if possible until a corrective patch is released. According to learn.microsoft[.]com, the situation underscores ongoing compatibility challenges between DRM systems and security updates in Windows.
