As a reminder, these release notes apply to those who are in the Experimental (26H1) channel.

Changes and improvements gradually being rolled out

This update accelerates app launch and core shell experiences such as Start menu, Search, and Action Center.

New accessibility setting: Screen tint

We're introducing screen tint, a new accessibility setting that applies a color overlay across your entire display, softening its intensity so it's easier on your eyes throughout the day. If bright, saturated screens leave you with tired or sensitive eyes by the end of a long session, screen tint can help. Screenshot showing UI for screen tint in Accessibility, with color presets and a strength slider.
To get started, open Settings > Accessibility (or press Win + U) and look for screen tint under the Vision section. From there you can:
- Pick from six preset colors or choose a custom color of your own.
- Adjust the tint strength slider from a subtle wash to full intensity.
Night light warms your display to reduce blue light that can interfere with sleep. Screen tint reduces overall screen intensity to ease eye fatigue and light sensitivity during the day. They tackle different problems and you can use both at the same time, one working on warmth and the other on intensity.
Note that turning on screen tint will disable color filters, and vice versa. If you currently rely on color filters, you may need to keep screen tint turned off.

These builds can be unstable and may be released with limited documentation.
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.
