Microsoft Acknowledges DRM Problems in Windows 11 Update for September 2025

Users have reported a range of issues following the rollout of the Windows 11 September 2025 Update (KB5065426).While some individuals have installed the update without problems, many have encountered significant errors, particularly related to Digital Rights Management (DRM).According to Windows Latest, this update has triggered a series of complications that extend beyond just installation failures.

Microsoft has acknowledged that the underlying problems may date back to the previous update, KB5064081, released in August 2025. If you had installed either KB5064081 or the latest September update, you might experience performance issues, especially when viewing videos using specific applications.

Impact on Video Playback

Reports indicate that some users are experiencing video playback disruptions, including jitteriness or sluggishness. While it appears that mainstream video streaming services like Netflix have not been affected, the complications predominantly impact digital television and DVD applications that rely on the Enhanced Video Renderer component, which enforces HDCP and DRM.

If you frequently use digital applications that utilize Enhanced Video Renderer technology, you might notice a decline in video performance following the September update. Microsoft has stated, “We are working to provide resolutions in future Windows updates and will provide more information when it is available, ” according to their support documentation.

As of today, September 22, we anticipate the release of an optional update within the week. This upcoming patch may address the existing DRM-related issues, although users are advised that other concerns have also emerged following the September Patch Tuesday.

Additional Issues Following the Update

Another significant problem reported is related to the Javelin anti-cheat engine, critical for numerous games, including popular titles like FIFA, F1, Battlefield, and NFL. While these issues have not been universally experienced, they can hinder gameplay for some users.

Moreover, players of DirectX 9 games have reported rendering problems, particularly during the opening sequences. Texture and color inconsistencies have diminished the overall gaming experience. Additionally, updates might affect Microsoft Ink services, leading to functionality issues in related applications.

A user highlighted, “KB5065426 update has completely broken Microsoft. Ink.dll in. NET applications, ” emphasizing the widespread impact of this update.

There are ongoing reports of difficulties with PowerShell. Microsoft has not only acknowledged these issues but also categorized them as affecting specific users, particularly when utilizing PSDirect connections. Nonetheless, the company has deemed this a rare occurrence.

Another significant concern arising from the update includes disruptions to Server Message Block (SMB) v1 functionality. This could hinder your ability to share or connect to network-shared files. Microsoft is actively working to rectify these challenges in an upcoming release of Windows.
