Windows 9 Start Screen and Charms

A little bit more refinement in this mock-up. Basically, the charms bar has been moved to the left side (with Power, Search and Back) and would be activated by simply hovering over the Start button. Clicking the button will reveal the Start Screen. As far as locking or switching accounts, that is done through the account picture on the taskbar like what was seen early in the Windows 8 milestones. Also, the taskbar icons have been re-worked some and in this mock-up, show the differences between currently selected, running and hover.
