Microsoft proves Windows 11’s modern UI can beat legacy Win32, if it works hard enough

Microsoft is modernizing Windows by transitioning legacy features to its WinUI framework, including a redesign of the Run dialog. The new Run dialog, implemented with C#/WinUI 3, shows improved performance with a median time-to-show of 94 milliseconds, compared to 103 milliseconds for the legacy version, reflecting an 8.7% speed increase. Despite this improvement, Microsoft acknowledges that WinUI requires further performance enhancements in various areas. The development of the Run dialog utilized .NET AOT compilation to achieve native code speed while maintaining C# flexibility. Concerns about performance on lower-end machines persist, as seen with the Task Manager and File Explorer. Microsoft aims to modernize Windows features without sacrificing performance, with the Run dialog serving as a potential model for future updates.

A major Windows 11 UI redesign is coming, Microsoft is dumping legacy code for WinUI

Microsoft is transitioning more Windows UI elements to WinUI3, moving away from legacy UI inconsistencies that have led to increased RAM usage. WinUI serves as the native UI framework designed to replace older technologies like Win32 and UWP. An early preview of the redesigned Properties dialog, rebuilt in WinUI, showcased new native elements. Microsoft plans to bring more Windows UI to WinUI3, despite previous issues with hastily integrating dark mode into legacy code. The decision to rebuild the Properties dialog indicates a commitment to investing resources in this initiative. Updates across various dialogs and system components are ongoing, with the file copy dialog already rewritten in WinUI. The Run dialog has also transitioned to WinUI, loading faster than its predecessor. However, the Start menu rewrite is being cautiously managed due to current memory usage issues with WinUI. Microsoft is actively working to enhance WinUI’s memory usage and integrate it with the Windows system compositor for improved performance.
