Removes the Back->ESC mapping that normally occurs when menus are visible, and for applications that subscribe to this behavior. If you enable this policy, a button assigned to Back will not map to ESC. If you disable this policy, Back->ESC mapping will occur. If you do not configure this policy, Back->ESC mapping will occur. Fix: (1) GPO: User Configuration\Administrative Templates\Windows Components\Tablet PC\Hardware Buttons!Prevent Back-ESC mapping (2) REG: HKEY_USERS\SOFTWARE\Policies\Microsoft\TabletPC!PreventButtonBackEscapeMapping
