Microsoft is rolling out a new Experimental Windows Insider channel, transitioning users from the Dev Channel to the Experimental Channel with updates from the 26300 series builds. Over the coming weeks, Canary testers using the 28000 series will be moved to the Experimental (26H1) Channel, while those on the 29500 series will go to the Experimental (Future Platforms) Channel. The latest build for the Dev Channel is 26300.8289, which includes enhancements such as improved Windows Update functionalities and options to skip updates during the out-of-the-box experience. Dev Channel testers can enable the Experimental Channel option through Settings. The Experimental Channel will allow switching between 26H1 builds and future platform builds. Canary Channel testers have access to build 28200.1873, which rebrands the Xbox full-screen experience and improves the Touch Keyboard. Additionally, build 29576.1000 is available for testers on the 29500 series, featuring a redesigned volume slider and new metrics in Task Manager. Beta Channel Insiders can download build 26200.8283, which includes minor adjustments to the Start Menu and print drivers, but the new Beta experience will not be immediately available.
