Source: Windows Central 2021 is a big year for Windows. Even without Windows 10X, Microsoft has a lot of plans for the Windows platform thanks to Sun Valley and its renewed interest in bringing OS innovation to market. Microsoft told us last year that it would be reinvesting in the Windows platform in 2021, and it is now almost time to see the result of that reinvestment. We know Microsoft is planning to hold a dedicated Windows event soon, likely within the next handful of weeks. This event will be Microsoft's chance to prove to the world that it's still serious about Windows by unveiling its new Windows user experience (UX) and features that are designed to make using Windows better on PCs and tablets.
