September cumulative updates for Windows 11 and Windows 10 released. Such updates primarily focus on fixing discovered bugs and vulnerabilities, but may also include new features. Here are the details.

Microsoft has released a new preview build of Windows 11, number  27938, to Windows Insiders using the Canary channel. Recently, the branch name from which builds are released has changed to BR_RELEASE. This is due to internal development cycles of the operating system. The Windows Insider team treats these builds the same as builds from the RS_PRERELEASE branch. However, due to the branch change, some features have been temporarily removed from Windows 11 Insider builds. Microsoft plans to bring them back in the future. BR_RELEASE builds do not refer to any feature update for Windows 11.

Please note that the major build number for the Dev channel has changed to 26220. Windows 11 version 25H2 will have a major build number of 26200, and it is already available in the Release Preview ring.

Microsoft has officially released the source code for its 6502 BASIC interpreter under an open-source license. This continues the recently started trend of open-sourcing the historically significant software made by the company decades ago.

Windows 11 includes a built-in notification system to support full USB Type-C functionality. This feature delivers alerts related to connection issues, suboptimal charging performance, and incompatible accessories. These notifications depend on precise hardware configuration at the firmware level.

As of today, Windows 11 version 25H2 (Build 26200.5074) is available as an optional update for Windows Insiders enrolled in the Release Preview Channel. Users can manually check for updates through Windows Update and choose to install the feature update at their discretion. Once installed, devices will begin receiving monthly cumulative updates automatically.
