Windows 11 Performance Boost: Microsoft Focuses on Speed & Efficiency

Microsoft is recalibrating its strategy for Windows 11, shifting focus from aggressive AI integration to bolstering the operating system’s core performance and reliability. The move comes as the company faces criticism over the intrusiveness of its AI assistant, Copilot, and increasing competition from rivals like Apple, whose MacBook Neo is undercutting Windows-based laptops on price and quality. Pavan Davuluri, president for Microsoft’s Windows + Devices business, outlined the change in direction in a blog post, stating the company is “focusing on making Windows 11 more responsive and consistent, so performance feels smooth and reliable.” This includes improvements to application launch times and responsiveness of key Windows components, such as File Explorer, particularly when the system is under load. A key component of the performance push will be improved memory efficiency, lowering the baseline RAM usage of Windows itself to free up resources for other applications. Microsoft is also working to reduce latency in application interactions by migrating core Windows apps to the WinUI3 framework, its modern native UI. Many existing Windows applications currently rely on older frameworks and web-based layers, which can hinder performance. Testing in late 2025 revealed that File Explorer, even after optimizations to pre-load the application, started slower in Windows 11 compared to Windows 10 and consumed additional RAM, according to Windows Latest. Microsoft aims to address these issues with the WinUI3 transition, potentially leading to smoother animations and a more responsive user experience. The company is also addressing shortcomings in Windows search functionality. Currently, search results often include web results alongside local files and applications, creating a cluttered and sometimes frustrating experience. Microsoft intends to improve search latency and accuracy, delivering more relevant results and replicating a consistent search experience across the taskbar, File Explorer, and Settings. Beyond these core areas, Microsoft has pledged to improve driver reliability, Bluetooth stability, and USB connectivity. The company also aims to enhance Windows’ reliability when waking from sleep, especially when connected to laptop docking stations. These changes represent a significant shift in Microsoft’s approach to Windows 11, acknowledging user concerns about performance and stability while responding to competitive pressures. The updates will first be rolled out through the Windows Insider program before being released to the general public.
