Windows 10 Technical Preview Build 10074 now available April 29, 2015
Reference: Gabe Aul New Windows 10 Insider Preview Build 10074 now available "Hi everyone from the Build 2015 conference happening right now in San Francisco! If you haven’t already, check out Terry’s blog post about all the Windows 10 announcements we made today. If you’re at Build this week or at Ignite in Chicago next week – keep your eye out for me and say hello!
Today we have a new build available to both the Fast and Slow ring for Windows Insiders (that means we’ll have ISOs available too for those of you who like a clean install.) With this build we continue to evolve the features and design for Windows 10, and you’ll see a lot of subtle changes and improvements, many of which were influenced directly by Windows Insiders. One of those changes is the reintroduction of some Aero Glass elements in the UI, but there are many more things throughout the product as well. We continue to use your feedback directly day to day in how our feature teams operate, and we hope that Windows 10 will be the best version of Windows yet because you had a direct hand in its creation.
One other subtle change that you’ll notice is that we’ve changed how we talk about the builds from “Technical Preview” to “Insider Preview” to reflect the importance of the Windows Insider community in how we’re building Windows 10."
What’s new: 1) A new Live Tile animation for Start in addition to in addition to some performance and stability improvements for Live Tiles. 2) Better support high DPI displays and multi-monitor systems. 3) Aero Glass from Windows 7 make a comeback. I'm my opinion its better but not all the back to full aero. Also no means to adjust the transparenece.
