In this article, we will talk about the Big Windows K2 Features Coming in 2026 such as New Performance, File Properties Dialogs, Memory Efficiency and more.
Windows K2, for those of you who don’t know, is Microsoft’s Codename for the internal plan that wants to fix Windows 11 and to address the main painpoints that users have reported for years now.
New WinUI 3 Implementation in Windows 11
Microsoft has strengthened the fundamentals of WinUI 3 and extended it into more of the Windows shell, including Widgets and the new Run experience, with Autoplay dialog and more File/Folder Properties dialogs coming soon to Windows Insider Preview Experimental builds. And with substantial improvements in memory efficiency and latency, these investments are strengthening the platform foundation needed to accelerate the modernization of Windows 11 and the broader application ecosystem.
New Performance Improvements
Microsoft is continuing to invest across the full stack, from the kernel and shell to the apps and developer tools built on Windows, so performance improvements benefit the broad range of ways people use Windows. Building on the responsiveness and scheduler work we described in May, application launches and experiences like Start, File Explorer, Search, and Snipping Tool are faster and more responsive. Our focus has been on improving these experiences, so they are responsive, free of stutters and delays, and customers enjoy a reliable experience every time. Boot and logon times are also improved. Additionally, developers benefit from faster compile times, streamlining enterprise workflows.
New Memory Efficiency
Alongside all of these areas, Microsoft has steadily been introducing several improvements to the memory efficiency of Windows, from taking advantage of a more efficient memory allocator to reduce overhead across apps and components, continued tuning of WinUI 3 so that apps built on it use less memory by design, as well as driving efficiencies across Chromium and Webview2 components when they appear in the operating system.
New Features Coming in 2026
- Onboarding and setup. Delivering a faster and more efficient out-of-box experience.
- Memory optimization for 8GB and above. Reducing Windows memory footprint to deliver a fast and responsive Windows experience across the PCs customers use every day.
- Family. Providing a faster set up and making it easier for families to access useful parental controls.
- Voice. Making voice more natural and fluid to interact across the apps you use every day.
