Microsoft has major plans which are a big deal for Windows 10 in the future. The UI overhaul will be felt across the entire Windows 10 desktop experience, from the Action Center through to the Start menu, and pretty much everything in-between.

It’s been reported that Microsoft is taking elements of Windows 10X to use in Windows 10 – after 10X got shelved – and that the Sun Valley redesign will make extensive use of rounded corners, plus floating menus, aiming to achieve a more modern look overall (based on Fluent Design concepts), complete with a raft of refreshed icons and animations. In terms of porting stuff over from Windows 10X, the most recent leak indicates that the Action Center design from 10X could be brought across – or at least it’s present, albeit hidden, in recent preview builds of Windows 10.

The advert for a Program Manager in the Windows IXP (Interactive eXperiences Platform) team in the US (Redmond), which was spotted by Windows Latest, states that Microsoft is “now on a multi-year journey to revolutionize the Windows UX platform by delivering best interactive experiences, showcasing cutting-edge hardware”.

Big things are expected from the ‘Sun Valley’ interface revamp which is expected to arrive with the 21H2 update towards the end of the year, based not just on a multitude of leaks, but also on the kind of language seen here which Microsoft has used in the past, too.

Windows Latest also points to another job listing, which has since been taken down, that enthuses about a “multi-year journey to re-imagine this platform with the goal of enabling the best interactive experiences on Windows”.
