In Windows 8, Microsoft has separated system and application controls into multiple panels, some of which are accessed from the Charms bar (shown) while other are embedded in application ribbons. Seen here is the Desktop's PC Settings Charm bar and its link to the traditional Control Panel, which still contains most system settings. Those accessible from the PC Settings panel are for app-notification settings, search settings and for certain keyboard preferences. Formatting, defrag and drive controls are baked into the Windows Explorer ribbon. The top portion of the Charm bar varies depending on the active application.
