When using the VUEM administration console to configure the Control Panel to display or hide applets with special characters such as ( or ', these applets are not displayed/hidden in the user session.
Cause and Partial Resolution
This is caused by a bug with the Windows Multilingual User Interface.
To resolve this issue, you can use the canonical names of the control panel applets for system applets: http://msdn.microsoft.com/en-us/library/windows/desktop/ee330741(v=vs.85).aspx
Third party applets do not have canonical names, and so this method will not work for them.
