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.
