According to WindowsCentral, Microsoft is preparing a massive update for Windows 10 for 2021, codenamed Sun Valley. It will focus exclusively on visual changes to the operating system interface.
According to media reports, Microsoft wants to “spice up” the Windows 10 user interface. Visual improvements will be made to the Start menu, Action Center and File Explorer. Users should expect modernized designs, improved animations and new features. In addition, Microsoft will continue to add dark themes to various menus and OS sections.
The Sun Valley visual update will be released as part of a major Windows 10 Cobalt update in late 2021.
