Microsoft's upcoming PC OS, Windows 8 , could offer a cut-down version of its user interface, taking on some design elements from the Windows Phone 7 UI. The new desktop interface is set to be known as 'Aero Lite', according to an msstyles file that was discovered by Twitter user AngelWZR . Windows Aero is the desktop experience already in use on Windows 7, incorporating graphics and window layouts with animations and glass-like effects. Have you felt the bubbles melt? Word on the street is that a number of icons from the Metro UI on Windows Phone will make their way to Windows 8 via "Aero Lite". Aero Lite is also said to include some flat Metro (Windows Phone) styles for users who can't run the full software – which, it now seems more likely than ever, will include 3D graphics. Some icons from Aero Lite have also leaked, including some thrilling arrows, a horrible Windows button and a lot of crosses and boxes.
