Reminder for Windows Insiders in the Experimental (26H1) channel

- Many features in the Experimental (26H1) channel 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.
- The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
- 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.
