Windows Insider reboot begins: Here's what's new in the first-ever Experimental Preview build

Windows Insiders will be transitioned into three channels with clear definitions.

Starting today, Windows Insiders are being shifted to the newly formed Experimental Channel and the revamped Beta Channel. Most Insiders in the Dev Channel will be placed in the Experimental Channel, while those in the Beta Channel will be in the updated Beta Channel.

Windows Insiders in the Canary Channel will be transitioned to either the Experimental (26H1) Channel or the Experimental (Future Platforms) depending on the Canary build their PC is on, but that transition will happen over the coming weeks.

Microsoft is rebooting the Windows Insider Program with a new focus, a clearer structure, and a deeper commitment to listening to feedback. Part of the change is a simplified channel strategy that reorganizes the Insider Channels in a way that makes sense.

The Experimental and Beta Channels will allow Insiders to test features and provide feedback without having to jump through hoops or use third-party tools to enable features. There's a clear separation between the channels that I'm excited to see.

Microsoft outlines the transition in a Windows Insider blog post:

"To ensure quality and reliability of the program changes, we will be rolling out the changes in a phased approach. Starting today, we will begin moving users in the Dev Channel to Experimental. Delivering on our promise to allow Insiders in Experimental to enable new experiences before they roll out to your device, if you are in the Dev Channel and do not see the new Experimental channel UI, you can enable it yourself by going to Settings > Windows Update > Windows Insider Program > Feature flags and toggling on the new experience."

The rollout will span the coming few weeks and eventually include Canary Channel Insiders as well.

Microsoft kicked things off with the first-ever Experimental builds and a Dev Channel Build. Here are some quick links to the change logs and a rundown of what's new in the first-ever Experimental build.

The biggest change is the ability to skip updates during the out of box experience. We knew this was on the way, and it's nice to see it hit the next phase of testing.

Before this change, users setting up a PC for the first time needed to sit through an entire update process, which could take up to half an hour. While it's important to keep systems up to date, having the option to skip those updates while setting up a PC is lovely.
