PHYSIX OBSERVATION

Microsoft loosening the Copilot key is effectively an admission that the earlier forced key change sparked backlash. The end of updates for 24H2 Home edition pushes users to upgrade, while Enterprise gets an extra year of buffer. The Emoji and touchpad improvements are routine iteration, but the ability to remap the Copilot key back to right Ctrl is a return to familiar experience for longtime users, and also hints that Microsoft is no longer pushing hard on the AI entry point.
