Microsoft to Replace Old Windows 11 Interfaces With WinUI 3
Windows 11 replaces legacy Windows 95 interface components with WinUI 3
Windows 11 is moving to eliminate interface elements dating back to Windows 95, replacing legacy components with modern frameworks like WinUI 3.
The Tech TL;DR:
- Microsoft is systematically rewriting legacy Win32 windows, dialog boxes, and management consoles into modern WinUI 3 and C# implementations.
- Preview builds already feature redesigned File Explorer properties, a modernized Run dialog with dark mode and command history, and updated file transfer UIs.
- Deep administrative architectures like the Microsoft Management Console and the legacy Control Panel remain active development challenges due to deep enterprise dependencies.
Microsoft is overhauling its operating system interface to remove visual elements originating from decades-old software releases. While Windows 11 relies heavily on Fluent Design, many system dialogs and administrative applets still retain UI layouts from Windows 95.
Design Modernization Underway Across System Utilities
The modernization effort is structural rather than purely cosmetic, according to Marcus Ash, head of design and research for Windows and Microsoft devices, who confirmed that development work is currently underway. Ash noted that the goal is to create a cohesive user experience without breaking established workflows used daily by administrators and developers.
March Rogers, design director for the Windows organization, previously confirmed the existence of a dedicated initiative to rewrite obsolete windows. Several modern implementations are already appearing in preview builds, such as the File Explorer properties window and the file transfer dialog.
WinUI 3 Updates the Run Dialog and Print Management
The Run dialog has been reconstructed using C# and WinUI 3, adding command history and native dark mode support. This updated interface remains optional, requiring manual activation through advanced settings.
Additional updates target AutoPlay and introduce a new Print Management app to replace the aging console dedicated to printer configuration. The Reset This PC tool, which retained a visual style stemming from Windows 8.1, is also scheduled for replacement.
Legacy Consoles and Control Panel Present Engineering Challenges
Complex administrative utilities present the most difficult engineering challenge for the team. Device Manager, Event Viewer, and Services still rely on the Microsoft Management Console, requiring individual component reconstructions to avoid compromising established procedures used in professional environments.
The legacy Control Panel also remains an obstacle as engineers transition features into the modern Settings app. Hardware, driver, and specialized configurations still force the OS to spawn traditional dialogs for audio, mouse, and disk optimization settings.
