Microsoft's Gabriel Aul confirmed the new build was available in a blog post on Friday, while warning that not everything Microsoft talked about earlier this week would be available.
"Some of the new features that Joe demoed on Wednesday will be available for our Windows Insiders starting today with our newest build -- 9926," Aul wrote. "However, not everything you saw on Wednesday is included in this new build. Much is still in-progress and we're getting it out to you as fast as we can -- so you can try it out and give us feedback. Over the course of the next few builds, you will see us refine Windows 10 and continue to improve the experiences as well as quality and stability."
What Microsoft showed off in Redmond was Build 9924, which we played with as part of our preview. The build will download automatically overnight, or you can get it now by going to PC Settings > Update and recovery > Preview builds and clicking the Check Now button.
In a nutshell, here's what you should expect in the new 9926 build:
Cortana: Microsoft's digital assistant has been ported over from Windows Phone, and makes an appearance in Windows 10. We think that Cortana should interact with your Windows Phone, sending reminders to your desktop and taking over as a general search interface, to boot.
Notifications: The Cortana reminders should show up in your Action Center, the little icon in the bottom right-hand corner of your screen. Expect to see a lot more information there now that Cortana has been enabled!
Continuum: The new build should offer to put your Surface in tablet mode when undocked (or any other 2-in-1 that has the preview installed).
Full-page Start menu: If you'd like, you can expand the new Start menu into a full-screen Start page that looks a lot like the way Windows 8 set things up (but with icons still on the lefthand bar)
New Windows Store app: "It includes a new visual design which will be common across PCs, tablets, phones and the web. It works well within a window and can be updated independently from the OS (this matters because it allows for more frequent updates)," Aul writes.
New Xbox App: The new app was demoed for us in Redmond. Basically, expect a lot more detail about the games you and your friends are playing.
