Installing the latest update ensures you receive all previous updates, including important security fixes. What's new in Windows 11, version 25H2 Windows 11, version 25H2 includes all the features and capabilities delivered as part of continuous innovation to Windows 11, now enabled by default. To check out what's been released with the recent Windows updates, see Inside this update . Some features that were behind temporary enterprise feature control in Windows 11, version 24H2 are now enabled by default in version 25H2. These include: AI actions in File Explorer Click to Do (Copilot+ PC feature) Agent in Settings (Copilot+ PC feature) Version 25H2 includes Wi-Fi 7 enterprise connectivity . It also offers customers the ability to remove select preinstalled Microsoft store apps using policies . The Improved Windows Search (Copilot+ PC feature), initially announced as enabled by default in Windows 11, version 25H2, is expected to be available in a future update. Known issues in this update For the most up-to-date information about known issues for Windows 11, version 25H2, go to the Windows release health dashboard . Some Digital TV and Blu-ray/DVD apps might not play protected content as expected. Apps that use Enhanced Video Renderer with HDCP enforcement or Digital Rights Management (DRM) for digital audio might show copyright protection errors, frequent playback interruptions, unexpected stops, or black screens. Streaming services are not affected. The non-security September 2025 Windows preview update ( KB5065789 ) and later updates address problems affecting certain applications that use the Enhanced Video Renderer (EVR) with HDCP (High-bandwidth Digital Content Protection) enforcement . The non-security October Windows preview update ( KB5067036 ) includes additional improvements to address problems affecting applications using Digital Rights Media (DRM) for digital audio . Windows updates installed using the Windows Update Standalone Installer (WUSA) might fail with error ERROR_BAD_PATHNAME when installed by double-clicking a .msu file or using WUSA from a network share that contains multiple .msu files. These issues might occur on devices that installed updates released on May 28, 2025 ( KB5058499 ) or later. WUSA installs updates using the Windows Update Agent API , a method typically used in enterprise environments. It’s not commonly used in personal or home settings. This issue does not occur when: Only one .msu file is present in the network share. The .msu file is stored locally on the device. After installing an update using WUSA or by double-clicking the .msu file, and restarting Windows, you might still see a message on the Update History page in Settings indicating that a restart is required to complete the update. This is a temporary display issue and should resolve automatically. This issue is addressed in KB5079391 . The Windows 11 media creation tool (version 26100.6584), released on September 29, 2025, might not work as expected on devices with Arm64. Users may encounter an error message such as: "We're not sure what happened, but we're unable to run this tool on your PC." The media creation tool doesn't support creating media for use on Arm64 devices. However, Arm64 devices are normally able to create media for x64 devices—this functionality is not working as expected. This issue is unlikely to affect most users, as this feature is rarely used on Arm64 devices. This issue was resolved in KB5067036 . The Windows 11 Media Creation Tool was updated on October 28, 2025, and is available for Download Windows 11 . You can also download bootable media directly from the same page, under the section titled “Download Windows 11 Disk Image (ISO) for x64 devices.” Troubleshooting If you have questions or need help activating or troubleshooting Windows, support options are available to assist you.
