A menu is displayed in Windows 8 whenever you move the mouse cursor to one of the corners of the screen. The Charms Bar is displayed on the right when you move the mouse cursor to the upper or lower cursor here. On the left, you see the active app, and when you move the mouse down or up depending on whether you are at the top or bottom of the screen, you get a black bar with all apps that have been started but not closed in that session.
Some of you may run into issues with these interfaces, as they may make it harder to access other contents in this corners. If you are running applications or games in windowed full screen mode for instance, the close button may be at exactly the same position the top right Charms menu trigger is.
You have alternatives at your proposal. The Charms Bar can be opened with Windows-C, and Win-Tab lets you cycle through apps without the apps menu on the left.
Microsoft has added options to the operating system to disable the mouse over menus in Windows 8.
To disable the activation of the Charms bar when you move your mouse to the top or bottom right corner of the monitor, you need to get your hands dirty in the Registry.
Press Windows-r and type regedit in the run box and then enter to load the Windows Registry editor. Accept the prompt that appears. Use the left sidebar menu to navigate to the following key in the Registry:
Right-click on ImmersiveShell and select New > Key. Name that key EdgeUI. Right-click on EdgeUI and select New Dword (32-bit) Value and name it DisableCharmsHint. After you have created the value, double-click it and change its value from the default value of 0 to 1.
This disables the corner mouse over interface on the right side. If you ever want to enable the feature again, simply change the key back from 1 to 0 to do so.
If you have skipped the above paragraph go back and follow the instructions to create the EdgeUI key in the Registry. Right-click EdgeUI afterwards and select New Dword (32-bit) Value from the context menu and name it DisableTLcorner. Double-click the new entry and change the value to 1 from its default value of 0.
If you ever want to restore the corner activation, simply switch the value back to 0 to do so.
If you disable one or both edge interfaces you are left with displaying the interfaces with keyboard shortcuts. The easiest way to display the Charms Bar then is to use Windows-C, and to switch apps Win-Tab.
