Overview
- Microsoft published the 26H2 enablement package on September 29 to activate features already delivered through monthly servicing updates and to reset Windows 11’s support lifecycle.
- The update exposes Low Latency Profile, which briefly raises CPU clock speed for Start, Search, Notification Center, and app launches to reduce small pauses and make the UI feel more responsive.
- Early tests and user reports from multiple outlets show some PCs using about 1.5–2GB less RAM after moving to 26H2, though results vary widely by hardware, startup apps, and cached memory.
- Microsoft rolled many changes in staged releases, so some machines saw optimizations earlier and some users forced features with ViVeTool, making benefits uneven across devices.
- Microsoft has not published detailed technical notes tying 26H2 to specific RAM savings and is expected to discuss its broader memory-efficiency work at its upcoming October event.
