Microsoft Windows 11 ~~transition and~~ transition, requirements and updates

Following the end of support for Windows 10 on October 14, 2025, users have transitioned to Windows 11 through official methods like Windows Update. To qualify for a free upgrade, devices must meet strict hardware and security requirements, including a compatible 64-bit CPU, 4 GB of RAM, 64 GB of storage, and support for UEFI, Secure Boot, and TPM 2.0. Microsoft has focused on optimizing the user experience and system performance. For new ARM-based PCs, such as Copilot+ devices using Snapdragon processors, Microsoft is modifying the Out-of-Box Experience (OOBE) to allow manufacturers to defer non-essential updates. Performance is further enhanced through features like hardware-accelerated GPU scheduling and DirectStorage. In mid-2026, Microsoft prioritized a memory management overhaul to address rising RAM costs and the high resource demands of modern AI services. This initiative aims to improve efficiency for devices with at least 8 GB of RAM by implementing a more efficient memory allocator, fine-tuning the WinUI 3 framework, and optimizing Chromium and WebView2 web components. While the Windows 11 26H2 update has reportedly reduced memory usage by approximately 1.5 GB to 2 GB in certain scenarios, early feedback indicates that 8 GB devices may still face pressure from background processes and AI integration. By October 2026, reports emerged regarding further memory optimization. While the official 26H2 update is reportedly only available for computers with at least 16 GB of RAM, some users have demonstrated that Windows 11 can operate with significantly reduced consumption. In mid-October 2026, Microsoft released cumulative update KB5127648, introducing interface and performance enhancements. File Explorer received updates including streamlined web previews for HTML files and automatic PDF previews. On October 14, 2026, Microsoft announced significant performance updates, claiming the operating system is now up to 20% more responsive.
