Some Digital TV and BluRay/DVD applications might experience problems playing protected content. Applications using Enhanced Video Renderer with HDCP enforcement or Digital Rights Management (DRM) for digital audio might experience copyright protection errors, frequent playback interruptions, freezing or black screens. This issue does not impact streaming services.

Resolution: This issue is partially resolved. Problems affecting certain applications that use Enhanced Video Renderer with HDCP enforcement have been addressed in the September 2025 Windows preview update (KB5065789), and later updates. We recommend you install the latest update for your device as it contains important improvements and issue resolutions, including this one.

However, some applications using DRM for digital audio might continue to experience problems.

Next steps: We are working on a permanent fix for applications that still experience this issue and will provide more information when it is available.

Affected platforms:

Client: Windows 11, version 25H2; Windows 11, version 24H2
Server: None

Windows updates installed using the Windows Update Standalone Installer (WUSA) might fail with error ERROR_BAD_PATHNAME, when the update is installed using WUSA or double-clicking a .msu file from a network share that contains multiple .msu files.

WUSA is a method of installing updates using the Windows Update Agent API which is typically only employed in enterprise environments. It is not common in personal or home settings.

Please note that this issue does not occur when there is only one .msu file in the network share or when the .msu files are stored locally on the device. In addition, after installing an .msu file by double-clicking or using WUSA and restarting Windows, you might notice that the Update History page in Settings continues to indicate that a restart is required to complete the update. This is temporary and should be resolved on its own.

Workaround: To work around this issue, save the .msu files locally on the device and install the update from this location. Also, if you’ve restarted Windows after installing an .msu file via WUSA, please wait 15 minutes or more before checking the Update History page in Settings. After this short delay, the Settings app should properly indicate if the update installed successfully.

Mitigation: This issue is addressed using Known Issue Rollback (KIR) and is resolved automatically for most home users and non-managed business devices. Restarting your Windows device might help the resolution apply to your device faster.

IT admins can resolve this issue for managed devices which have installed the affected update and encountered this issue. It can be fixed by installing and configuring the Group policy listed below. For information on deploying and configuring these special Group Policy, please see How to use Group Policy to deploy a Known Issue Rollback.
