By default, Windows hides the Event Viewer, Computer Management and other Administrative Tools from the Start screen. If you use these applications frequently, you can easily unhide them.
From the Start screen, mouse over to the bottom or top right corner of the screen and click the Settings charm. You can also press WinKey-C to view the charms.
Click the “Settings” link under Start and set the “Show administrative tools” slider to “Yes.”
The Administrative Tools will appear on the Start screen and in the All Apps list.
