You'll be able to access Teams from Windows, Mac, Android or iOS. Teams is getting a face-lift and is pinned on the Windows 11 Taskbar, making it easier to access (and a bit more like Apple's FaceTime).
While they've been around for a while (remember desktop gadgets on Windows Vista?), including in a recent Windows 10 update, you can now access widgets directly from the Taskbar and personalize them to see whatever you'd like. (Note that Android apps will not be available upon the initial release of Windows 11.) There were a couple of ways to access Android apps on Windows 10, especially if you had a Samsung Galaxy phone, but this will make it native. Android apps will be coming to Windows 11 via the Amazon Appstore, which will be accessible from within the updated Microsoft Store. Windows 11 features a clean design with rounded corners, pastel shades and a centered Start menu and Taskbar.
