Users are complaining that the new Windows version of Outlook is running slowly.

Microsoft has introduced two versions of Outlook in Windows 11: Outlook Classic (a Win32 desktop application) and the New Outlook. Users have reported significant performance issues with the New Outlook, noting a lag of approximately 10 seconds for tasks that Outlook Classic performs instantly. The New Outlook operates on WebView2, which involves multiple processes and higher memory consumption, while Outlook Classic runs as a single process. Microsoft is aware of these performance challenges and is testing a new API called 'Delayed Message Timing' to address them. Users find Outlook Classic to be more reliable and faster, particularly for businesses that need efficient notification processing.

Microsoft reveals Teams can’t run well on low-RAM PCs, builds Efficiency Mode after years of bloat

Microsoft Teams is testing a new feature called "Efficiency mode," which will be available to all users by the end of June 2026. This mode aims to enhance performance on PCs with limited RAM, particularly those with 8GB RAM. Efficiency mode activates automatically when Teams detects that a device is hardware-constrained, optimizing performance by reducing video resolution and minimizing resource usage. The initial implementation includes changes such as dynamically adjusting video output and opening with a pre-selected chat. Users can opt out of Efficiency mode via the Settings menu. Microsoft is also exploring additional enhancements to improve chat access and reduce lag.

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

Microsoft is working to improve the user experience of WinUI 3 applications by addressing the issue of black tearing during window resizing. A fix is planned to be rolled out over the summer, as confirmed by March Rogers, Microsoft’s Partner Director of Design. Currently, WinUI 3 apps exhibit noticeable tearing during resizing, unlike UWP applications that resize smoothly. The Windows team is testing the smooth resizing code on native inbox apps before its broader rollout. Additionally, Microsoft is transitioning away from web-based architectures to enhance native app development, with plans to migrate the Windows 11 Start menu and system-level dialog boxes to WinUI 3. The company aims to rebuild trust with third-party developers through the Windows App SDK 2.0, which introduces new features and simplifies the development process for native applications.

Microsoft admits Windows 11 is still built on 90s-era Win32, and no one saw it coming

Users engage with the Win32 API when right-clicking files or launching desktop applications in Windows 11, a technology that has persisted since Windows 95. Microsoft’s Chief Technology Officer, Mark Russinovich, noted that the longevity of Win32 was unexpected, as it was not part of the company's original vision for the future. Despite attempts to replace Win32 over the past two decades, many users still have more Win32 applications than modern alternatives. Microsoft has introduced several frameworks to replace Win32, including MFC, WinForms, WPF, WinRT, and UWP, but none have fully succeeded. Developers have shown a preference for RAM-intensive web applications over native ones due to concerns about the stability of Microsoft's frameworks. Microsoft has introduced WebView2 to embed web technologies in desktop applications, leading to increased memory usage. In response to user needs, Microsoft is shifting back to native applications with WinUI 3, aiming to modernize Windows 11 while retaining access to Win32 infrastructure. The company is gradually replacing legacy Win32 UI elements with WinUI 3 components, improving performance and user experience.

Microsoft quietly deletes Windows 11 doc pushing 32GB RAM for gaming after outrage

Microsoft has retracted a support document that suggested 32GB of RAM as the ideal upgrade for gaming and 16GB as the baseline requirement. The document, published in early April, stated that 16GB RAM is practical for most players, while 32GB helps when running additional applications alongside games. Microsoft removed the document from its Learning Center, redirecting the URL to its homepage and blocking web archives from accessing it. This incident follows a previous document in February that also promoted 32GB RAM for serious gamers. Microsoft’s official system requirements for Windows 11 list a minimum of 4GB RAM, while most consumer PCs typically come with 8GB. The company has been advocating for Copilot+ PCs, which require 16GB of RAM. Windows 11 has faced memory management issues, and CEO Satya Nadella has acknowledged the need for optimization for low-RAM devices. Microsoft is reportedly working on enhancements to improve performance and reliability in Windows 11.
