Microsoft is updating Windows 11’s user interface by replacing legacy system elements that originated in Windows 95.
Recent preview builds showcase a redesigned File Explorer properties dialog that now utilizes WinUI 3 and supports dark mode.
The new properties UI appears in experimental build 26300.8935, initially for the deleted‑files dialog, with broader rollout planned.
Microsoft intends to replace outdated dialog boxes from Windows 8 and earlier with modern WinUI 3 components.
The overhaul aims to eliminate legacy UI elements, improving the overall look and feel of Windows 11.
Modernizing a legacy operating system presents challenges because much of the codebase remains unchanged, risking performance or compatibility issues.
Updating components such as the properties dialog can affect third‑party applications that rely on older interfaces, including archive tools, cloud storage clients, codec packs, and security software.
Despite the effort, WinUI 3 components promise faster startup and reduced instability when properly integrated.
The Windows Run dialog is also being rebuilt with a modern interface that adds functionality beyond visual changes.
Users can enable the new Run dialog via advanced settings and access it with the Win + R shortcut, where it offers quicker response and context‑aware suggestions, including fast navigation to the home folder.
These updates reflect Microsoft’s broader strategy to phase out legacy UI elements and align Windows 11 with contemporary design standards. The changes are expected to be delivered through incremental updates over the coming months.
