Microsoft aims to speed Windows with ‘leap forward’ in WinUI 3 perf

Microsoft has announced a 25 percent improvement in the performance of WinUI 3, specifically in File Explorer components. There has been a 41 percent reduction in memory allocations and a 45 percent decrease in function calls. Some optimizations may involve breaking changes, which will initially be optional for developers. The enhancements are intended to become the default in future iterations of WinUI and the Windows App SDK. Despite these improvements, developers have expressed concerns about WinUI 3's performance, noting it is slower than WPF and UWP. The reliance on WinRT interop for component actions is seen as a significant factor hindering speed. Additionally, there are historical tensions regarding the adoption of Microsoft's frameworks within the Windows and Office teams, leading to skepticism about their reliability.

Microsoft’s Windows K2 overhaul is making File Explorer launch much faster

Microsoft is reassessing its strategy following criticism and a decline in user satisfaction related to its AI tool, Copilot. The company is unwinding some Copilot integrations and reallocating resources to address issues with Windows 11, particularly focusing on improving File Explorer. Windows K2 will enhance File Explorer's performance, utilizing the WinUI 3 framework, which aims to streamline operations. Recent benchmarks show significant reductions in resource consumption for File Explorer, including 41% fewer allocations, 63% fewer transient allocations, 45% fewer function calls, and a 25% reduction in time spent in WinUI code. Improvements are expected to be rolled out soon.

What is Windows K2? Inside Microsoft’s big plan to SAVE Windows 11 and win back trust from users.

In March, Pavan Davuluri, the president of Windows, acknowledged the need to address significant "pain points" within Windows 11 to restore user trust and improve its reputation by late 2026 and into 2027. Microsoft aims to optimize Windows 11 for competitive gaming performance against steamOS and is implementing upgrades to File Explorer, including “instant filename search.” Windows Update is being improved for reliability, with updates planned to occur monthly. Efforts to debloat Windows 11 will reduce memory usage and the operating system's footprint. The K2 initiative focuses on enhancing user experience by reintroducing features like movable and resizable Taskbar and leveraging the WinUI 3 framework for performance improvements. A new System Compositor for WinUI 3 aims to reduce latency and memory overhead, with a 60% performance increase planned for the rebuilt Start menu. Microsoft will eliminate ads from the Start menu and adjust default settings for the Widgets Board. The K2 initiative is ongoing, shaping the future of Windows 11 without a defined completion date, with changes already being rolled out and more expected to be previewed over the summer.

Ookla’s Windows 11 Speedtest mockup looks suspiciously like macOS

Ookla and Microsoft announced a partnership to integrate Speedtest as the network performance testing platform across Bing and Windows, allowing Windows 11 users to check their internet speed from the taskbar. This feature was initially available to Windows Insiders in February 2023. A humorous remark by Rafael Rivera, a Windows Dev MVP, suggested that Ookla leaked a glimpse of the Windows vNext UI, which appeared to include elements from macOS. The incident has sparked discussions about design trends and user interfaces in the tech community.

Microsoft announces major Windows 11 updates designed to fix biggest flaws

Microsoft has announced plans to enhance Windows 11, focusing on user feedback from the past two years. Key improvements will include better system performance, app responsiveness, and user interface adjustments. Users can expect enhancements in tools like File Explorer and the Windows Subsystem for Linux, with a goal of a more responsive and less resource-intensive operating system by year-end. The Taskbar will be repositionable, allowing customization, and the Windows UI framework, WinUI, will be expanded across more system areas. Windows Update will offer users greater control over updates, including the ability to pause them indefinitely. Microsoft aims to improve reliability by strengthening the Windows Insider Program, increasing OS and driver reliability, and enhancing Windows Hello biometric authentication. The focus areas for improvements are Performance, Reliability, and Craft, with specific goals outlined for each category, such as reducing resource usage, enhancing memory efficiency, and improving the search experience.

This Linux project proves you can bring back Windows 8 – but not why you should

A Linux developer, operating under the GitHub handle er-bharat, is creating a desktop environment called Win8DE that resembles the aesthetics of Windows 8. The project is currently in its alpha stages, specifically version 0.5.0, and aims to provide a user interface suited for touchscreen devices. The developer's efforts highlight a gap in the market for a Windows 8-inspired theme for Linux environments, as existing themes do not replicate the card-like UI of Windows 8. The installation process for Win8DE has presented challenges due to dependency issues typical of alpha software.

Copilot AI: What You’re Missing on Windows 10 PCs — Virtualization Review

Microsoft's Copilot AI experience differs significantly between Windows 11 and Windows 10. On Windows 11, Copilot is integrated at the system level, allowing it to perform tasks such as opening specific Settings pages, toggling system settings, launching built-in applications, and providing contextual guidance with UI navigation. In contrast, Windows 10 users can only access Copilot through browser-based interfaces, limiting its functionality to providing written instructions without the ability to execute actions or interact with local system features. Copilot on Windows 10 lacks awareness of the operating system and cannot manage system configurations or settings directly, while Windows 11 allows for direct interaction with cloud-managed settings.

As Windows 10 hits EOL, Microsoft says it’s designing Windows 11 for AI

Microsoft has introduced a new design blueprint for Windows 11 that focuses on AI integration, as outlined by Windows Design Director Diego Baca. The company aims to create a user-friendly experience, learning from past mistakes with Windows 8. Windows 11 will see gradual design changes that enhance user experience without shocking users with a complete overhaul. Key design principles include "Intentional innovation," "Craft + scalable systems," "Tailored for all," and "Secure, trustworthy, and compliant by design." Microsoft plans to maintain a stable core design while incorporating AI features, such as contextual menus and personalized experiences based on user activities. The Fluent design system will be emphasized, with updates to classic applications like Microsoft Paint and Notepad. Security is a priority, with measures embedded early in development to ensure AI functionalities are safe. Speculation about Windows 12 suggests it may further integrate context-aware features and diverse interaction methods, while retaining the design principles established in Windows 11.
