[DESK] Set the default value for the placement combobox and load the monitor bitmap before the registry is accessed. Lower the requested access rights for RegOpenKeyEx to HKEY_QUERY_VALUE. In case RegOpenKeyEx fails, simply return to the calling function. Remove result and varType variables. By Ricardo Hanke. CORE-9365
