Microsoft's Windows Insider program has transitioned Dev Channel testers to the new Experimental Channel and is expanding this initiative to include Canary testers on the 28000 series builds, who will also move to the Experimental (26H1) Channel. The new Windows Insider experience introduces feature flags in Windows Update settings, allowing testers to toggle features on and off. Microsoft plans to roll out new features through Controlled Feature Rollouts (CFRs) and has stopped gradual feature rollouts on the updated Beta Channel.
Recently, Microsoft released four new builds available via downloadable ISOs. Canary testers on 29500 series builds will soon transition to the "Experimental (Future Platforms)" Channel and can currently download build 29580.1000, which includes a revamped Feedback Hub with a 500 MB file upload limit and design improvements. For Canary testers on the 28000 series, the transition to the "Experimental (26H1) Channel" follows the installation of build 28020.1921, which enhances the Task Manager app.
Insiders who moved from the Dev Channel to the Experimental Channel can download build 26300.8346, featuring improvements such as a Widgets board that remains closed by default, a redesigned Run dialog, promotional app recommendations in Windows Share for Microsoft Entra account users, sharper file thumbnails in File Explorer, and enhanced Windows Magnifier functionality. The Beta Channel build 26220.8340 includes similar Windows Share improvements and minor UI enhancements for Task Scheduler. The Beta Channel is set to transition to a new experience that will eliminate Controlled Feature Rollouts.
