Microsoft is taking significant steps to enhance the native experience of Windows 11 by eliminating web-based components that have long plagued the operating system. Since its inception, Windows 11 has been criticized for its reliance on web wrappers and frameworks like React Native and Electron, which, while simplifying cross-platform development, have resulted in higher memory usage, sluggish performance, and a less-than-smooth user experience. The backlash from users has been palpable, leading to a growing sentiment against what many have termed “web app slop.”
Microsoft drops the “3” in WinUI to prove it won’t abandon developers
In a bid to regain the trust of developers, Microsoft has announced a pivotal change regarding its user interface framework. During the Build 2026 developer conference, Chris Anderson, Vice President of Software Engineering at Microsoft, addressed concerns about the company’s commitment to its native framework, WinUI 3. To signal a new era, the branding will simply be referred to as “WinUI,” indicating that there are no plans for a WinUI 4. This move aims to reassure developers that WinUI is now the definitive platform for modern Windows applications.
Microsoft confirms Windows 11 will use WinUI for more first-party shell features
To further solidify its commitment to native development, Microsoft is integrating WinUI into the Windows 11 shell at an accelerated pace. Anderson emphasized that users can expect to see a plethora of first-party features built directly on this native framework, moving away from the previously utilized web-based components. This shift is not merely cosmetic; it represents a fundamental change in how Microsoft approaches application development for its operating system.
In a dedicated effort to create “100% native” Windows applications, Microsoft has assembled a specialized team led by Partner Architect Rudy Huyn. This initiative aims to minimize reliance on WebView-powered interfaces, beginning with a significant overhaul of the Windows 11 Start menu, which will transition from React Native to native WinUI components. This change promises to enhance responsiveness and reduce resource consumption, marking a decisive step towards a more efficient operating system.
Microsoft says performance, memory usage, and fixing bugs are the highest priority in WinUI
At Build 2026, Microsoft took a pragmatic approach to discussing Windows quality, prioritizing the need to address foundational issues before introducing new features. Anderson highlighted that performance, memory optimization, and quality control are now the foremost concerns for the WinUI team. Recent investments have focused on reducing memory usage, a common complaint among developers, ensuring that Windows 11 runs more efficiently even under heavy load.
Windows 11 adopts a new system compositor for smoother UI performance
In addition to memory optimizations, engineers are transitioning to a new system compositor, which is expected to enhance performance for complex user interfaces. These architectural improvements are already being tested in public repositories and will soon be available in experimental previews of the Windows App SDK.
WinUI gains enterprise-focused DataGrid and Charting controls
Recognizing the gaps in WinUI, Microsoft is also responding to developer requests for essential enterprise controls. Anderson confirmed the addition of DataGrid and Charting components directly into WinUI, addressing the needs of business software, analytics dashboards, and reporting systems. This enhancement aims to provide developers with the tools necessary to build robust applications without relying on third-party libraries.
Microsoft expands open-source development for WinUI
In a significant cultural shift, Microsoft is moving towards greater transparency in its development process. The company has reached what it refers to as Phase 3 of its open-source journey, allowing developers to build and test WinUI publicly. Looking ahead, Phase 4 envisions a future where most development occurs in public repositories, enabling community engagement and contributions to shape the framework’s evolution.
Microsoft improves WinForms and WPF migration support
For developers maintaining legacy applications, Microsoft is enhancing interoperability between WinForms and WinUI, ensuring that existing software can adapt to modern technologies without requiring extensive rewrites. This approach acknowledges the reality that many enterprise applications are complex and cannot be overhauled overnight, thereby easing the transition to newer frameworks.
Microsoft UI Reactor and AI-assisted coding modernize native development
To modernize the development experience, Microsoft has introduced an experimental open-source project known as Microsoft UI Reactor. This C#-first declarative user interface framework allows developers to create native WinUI applications without the complexities of XAML. By simplifying the coding process, Microsoft aims to attract a new generation of developers who prefer more contemporary programming paradigms.
Moreover, this shift aligns with Microsoft’s broader AI strategy, as the more straightforward C# syntax is easier for AI coding assistants to comprehend and utilize, streamlining the development process.
The return of native desktop software benefits every Windows user
While web technologies will continue to coexist within the Windows ecosystem, Microsoft’s renewed emphasis on native development signals a promising shift for users. By prioritizing native applications, even budget Windows devices are poised to deliver improved performance and efficiency. The transition to a native shell, optimized file explorer, and responsive operating system reflects Microsoft’s commitment to enhancing user experience.
As the company encourages third-party developers to adopt WinUI, the prospect of future Windows applications that are cohesive, responsive, and resource-efficient becomes increasingly tangible. The era of web app slop may finally be drawing to a close, heralding a new chapter for Windows 11.
