Windows 11 version 26H2 was released on September 29, 2026, featuring performance enhancements for users with 16 GB or more of RAM, including a reduction in idle memory consumption by 2–3 GB and a 40% acceleration in application and system interface launches. The update package is 174 kilobytes and activates previously dormant features, resetting the support lifecycle for Windows 11 Home and Pro until October 2028. The Low Latency Profile is a key feature that boosts CPU clock speed temporarily during application launches, resulting in faster interactions, with independent tests showing a 70% improvement in opening the Start menu. Users with 16 GB or more of RAM have reported idle RAM dropping from over 10 GB to around 7 GB after the update. However, users with 8 GB of RAM have experienced minimal improvements and high idle memory utilization. Microsoft is committed to optimizing Windows for 8 GB machines, but early reports suggest limited gains from 26H2.
