Windows 10 now has one billion active monthly users thanks in part to the deprecation of Windows 7 in January. To celebrate the milestone, Microsoft’s chief product officer, Panos Panay, shared an Instagram video recounting the various iterations of Windows’ UI. The look of Windows 10 could keep evolving, it seems, as some eagle-eyed viewers spotted new types of windows, interfaces, and menus.
The video depicts a File Explorer window that looks noticeably different than the one Windows 10 users are accustomed to, and there’s a blink-and-you’ll-miss-it peak at a new calendar interface. Additionally, the tiles that pop up in the start menu have a more unified, monochromatic look that seems to jive with the user’s chosen color scheme. It’s not clear if these changes will actually be released or if they’re just internal mock-ups at Microsoft.
