Reminder for Windows Insiders in the Canary 28000 Series Channel (Soon transitioning to Experimental (26H1))​

• These builds can be unstable and may be released with limited documentation.
• The builds we release to the the Canary Channel represent the latest platform changes early in the development cycle and should not be seen as matched to any specific release of Windows. Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
• Many features in the Canary Channel are rolled out using Control Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
• The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
• Some features may show up in the Dev and Beta Channels first before showing up in the Canary Channel.
• For Windows Insiders who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
• Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, report those issues to us via Feedback Hub.
• To get off the Canary Channel, a clean install of Windows 11 will be required.
• Check out Flight Hub for a complete look at what build is in which Insider channel.
