Windows 10 build 10074, which was leaked recently, is now available for downloading officially. The new Windows 10 build brings back Aero Glass theme, that transparent and blurry glass effect present in Windows Vista and Windows 7, but the theme was dropped in Windows 8 and Windows 8.1. The blurred transparency effect can be seen on the Start Menu. It doesn't extend to app windows though.
"We've also heard loud in clear that many Windows Insiders want to see Aero Glass from Windows 7 make a comeback.", said Microsoft's Gabe Aul. Microsoft is running an A/B test with this build. 50 percent of Windows 10 testers will see normal transparency on the Start menu and taskbar while the other 50 percent will see a blur effect. Microsoft will choose which one to make the default effect for the new Aero glass theme based on feedback it will receive from Windows 10 testers.
