Reminders for Windows Insiders in the Experimental channel
- Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.8346).
- Many features are rolled out using Controlled 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.
- For Windows Insiders who want to be the first to try new features, see the available list of features to toggle on at the Feature flags page under Settings > Windows Update > Windows Insider Program.
- The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
- 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.
- 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, please report those issues to us via Feedback Hub.
- Check out Flight Hub for a complete look at what build is in which Insider channel.
