Microsoft has released Windows 11 Build 27954, to Insiders in the Canary channel. It introduces minor enhancements and fixes aimed at refining the overall operating system experience. A notable fix addresses an issue that previously blocked access to network resources using the legacy SMBv1 protocol via NetBIOS over TCP/IP (NetBT).
Recently, the branch name from which builds are released changed to BR_RELEASE. This is due to internal operating system development cycles. 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 represent any feature update for Windows 11.
