Microsoft is enhancing Windows 11 by reducing reliance on web-based components, which have caused performance issues. The user interface framework WinUI will now be referred to simply as "WinUI," indicating no plans for a WinUI 4, to reassure developers. Microsoft is integrating WinUI into the Windows 11 shell more rapidly, moving away from web components. A specialized team is focused on creating "100% native" Windows applications, starting with an overhaul of the Start menu from React Native to WinUI components. Performance, memory optimization, and quality control are top priorities for the WinUI team. A new system compositor is being introduced to improve UI performance, and enterprise-focused DataGrid and Charting controls are being added to WinUI. Microsoft is expanding open-source development for WinUI, allowing public testing and contributions. Migration support between WinForms and WinUI is being enhanced for legacy applications. An experimental project called Microsoft UI Reactor is introduced to simplify native application development using C#. This shift towards native development aims to improve performance and efficiency for all Windows users.
