Microsoft’s new Outlook takes 10 seconds to do what Outlook Classic does instantly on Windows

Microsoft's Outlook for Windows is facing criticism for its notification handling, particularly in the new Outlook version built on the WebView2 framework. Users experience a delay of approximately 10 seconds when clicking on email notifications, compared to the near-instantaneous access provided by Outlook Classic, which allows users to open new emails in about five seconds. The new Outlook consumes significantly more memory and CPU resources, using between 490 MB and 636 MB of RAM, while Outlook Classic operates within 117 MB to 148 MB. Despite updates aimed at improving the new Outlook, the core issue of notification handling remains unresolved. Microsoft is working on enhancements, but the performance limitations of the WebView2 architecture continue to affect user experience. Outlook Classic will continue to be supported until April 2029.

WhatsApp is eating 1.2GB RAM on Windows 11, even as Microsoft kills web app slop

WhatsApp for Windows, despite having a large user base of 3 billion globally and 1.6 billion on Windows, suffers from significant performance issues, including high RAM usage (400 MB before logging in and up to 1.2 GB while idling), slow message delivery, and a choppy scrolling experience. The app operates as a web wrapper using the WebView2 framework, which leads to inefficient resource consumption compared to native applications. Users across various hardware configurations report freezing, delayed messages, and instability. Microsoft’s Teams app also faces similar performance challenges due to its reliance on the same framework. There is a growing concern about the trend of developers opting for web applications over native ones, driven by a lack of trust in native frameworks. Despite Microsoft's push for native app development through WinUI, there is currently no native version of WhatsApp for Windows, while Meta has developed optimized versions for other platforms.

Microsoft is rewriting Windows 11 shell in native code, killing the web slop slowing your PC

Microsoft is enhancing Windows 11 by reducing reliance on web-based components, which have caused performance issues. The user interface framework WinUI will now be referred to simply as "WinUI," indicating no plans for a WinUI 4, to reassure developers. Microsoft is integrating WinUI into the Windows 11 shell more rapidly, moving away from web components. A specialized team is focused on creating "100% native" Windows applications, starting with an overhaul of the Start menu from React Native to WinUI components. Performance, memory optimization, and quality control are top priorities for the WinUI team. A new system compositor is being introduced to improve UI performance, and enterprise-focused DataGrid and Charting controls are being added to WinUI. Microsoft is expanding open-source development for WinUI, allowing public testing and contributions. Migration support between WinForms and WinUI is being enhanced for legacy applications. An experimental project called Microsoft UI Reactor is introduced to simplify native application development using C#. This shift towards native development aims to improve performance and efficiency for all Windows users.

5 things I learned after vibe coding my first app

Megan Ellis explored vibe coding, a method that simplifies app development for both experienced and novice developers, allowing users to create functional applications in minutes. She began her journey through a Google AI course that introduced her to Google AI Studio, where she found the learning curve to be gentle, completing a simple spreadsheet analyzer app in 30 minutes. Most vibe coding tools focus on web app development, but recent updates have made Android app creation more accessible. Although no coding experience is necessary to engage in vibe coding, there are significant security risks associated with the apps created, leading Ellis to refrain from publishing her work. She found troubleshooting to be easier than expected, thanks to AI tools that helped resolve issues quickly. Additionally, she can keep her apps private using AI Studio's share link feature, allowing her to use them without public exposure.

Microsoft is killing Windows 11’s web app slop, encourages devs to build native apps using WinUI

At the Build 2026 developer conference, Microsoft emphasized the creation of native applications for Windows 11, focusing on WinUI as the preferred framework over alternatives like Electron or React Native. The company is revitalizing Windows 11 with a commitment to quality, performance, and reliability, and has formed a dedicated team to develop native apps. Microsoft is rewriting the Start menu, previously built with React Native, and has reaffirmed its commitment to WinUI, dropping the "WinUI 3" label to signify stability. Chris Anderson stated that there are no plans for a new framework and that WinUI will be the production platform for Windows apps. Microsoft aims to address existing issues in WinUI, such as performance gaps, and is introducing new features like DataGrid and Charting support to attract enterprise developers. The company is also adapting WinUI for AI workflows and developing tools to assist developers in creating modern applications. While Microsoft acknowledges other frameworks, it seeks to position WinUI as the primary native framework for Windows. The Build 2026 conference marked a renewed focus on Windows, with plans to rewrite the Windows shell in WinUI for a cohesive user experience.

Microsoft admits modern Windows 11 apps actually resize worse than the old ones, fix coming this summer

Microsoft is working on a solution to address the black tearing issue during window resizing in WinUI 3 applications on Windows 11, with a rollout expected to begin this summer. March Rogers, Microsoft’s Partner Director of Design, confirmed that the Windows team is testing smooth resizing code on native inbox applications before extending the update to the Windows App SDK. The transition to WinUI 3 aims to replace inefficient web applications and improve user experience, with significant components like the Start menu and system-level dialog boxes being upgraded to WinUI 3. Additionally, Microsoft has launched Windows App SDK 2.0 to encourage third-party developers to adopt native app development, addressing previous issues such as bugs and lack of visual features.

Microsoft’s new Copilot turns into a Windows 11 sidebar that pushes your apps aside to make room

Microsoft is integrating its AI assistant, Copilot, into Windows 11 with a new docking feature that allows it to coexist with other applications. Users can access a drop-down menu in the title bar for "snapping" options, enabling Copilot to dock on the left or right side of the screen. The interface adjusts automatically to accommodate the docked Copilot, which can occupy space alongside other applications. Copilot has undergone several redesigns and is now packaged as an Edge-based wrapper, although the reasons for this bundling are unclear.
