We'll spend more time with the newly released Windows 10 Preview Build 10041 and share anything else that might be interesting.

This build brings a collection of new functionality and bug fixes. Some of the noticeable new features include transparent Start screen, improvements to Virtual Desktop, network fly-out from the taskbar, new text input canvas, and more. Keep in mind that this is still a Preview. The UI is coming together slowly, but there's still a lot of work to do.
