Some of the new features that Joe demoed on Wednesday will be available for our Windows Insiders starting today with our newest build – 9926. However, not everything you saw on Wednesday is included in this new build. Much is still in-progress and weâ??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.
This new build contains the first set of features unveiled earlier this week. Neowin has a bunch of screenshots.
