I hope that you were able to watch our live stream on Wednesday, where we shared more details on the Windows 10 experience. If you missed it, you can watch the video on demand anytime and read Terry Myerson’s blog post that recaps the latest Windows 10 news. As Terry mentioned, we continue to be humbled by the amount of feedback and excitement we’re seeing from the Windows Insider community.

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 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.   If you’re unfamiliar with the Windows Insider Program, this is our community who is helping us build Windows 10. If you’re not a Windows Insider yet, we’d love to have you join – see below. Also make sure you read the list of known issues at the end of this post before getting started.
