Microsoft has released cumulative update KB5083824 (Build 28020.1803) for Windows 11, version 26H1. This update is available for Insiders on the Canary Channel and represents a build belonging to the br_release development branch. Users on this channel will now receive updates for Windows 11, version 26H1 (Build 28020), which is activated on top of Windows 11, version 26H1 (Build 28000) using the Feature Enablement package KB5073122.

Canary Channel users should note that builds released to this channel represent the latest platform changes at early stages of development and are not tied to any specific Windows release. Features and functionalities included in these builds may never ship in the final version, as Microsoft tries different concepts and gathers feedback. Features may change, be removed, or be replaced, and some may never become available outside the Windows Insider program. Many features in the Canary Channel are rolled out using Control Feature Rollout technology. They first become available to a small group of Insiders, and then their availability expands as feedback is received and analyzed.
