Simple Change
Might I suggest that Microsoft switch the locations of the "power/restart/sleep" button and that of the "user profile" icon. This would place the "power" button right above the Start button on the Taskbar. I, and I'll bet most people use the power button far more often than that of the "user profile" button. Furthermore, less wrist movement is always better! Anyone at Microsoft ever heard of Carpal Tunnel Syndrome?
