- Support loading protocols like XP - Support most of the relevant EditFlags - Support reading/writing the AlwaysShowExt and BrowserFlags properties - Loads the list much faster with optimized code and delaying the large icon and description string - Reduce the number of magic buffer sizes by replacing them with defines that are in the ballpark of being correct - Implemented column sorting - Removed custom icon extraction code - Removed IDS_FILE_EXT_TYPE string because it must be the same as IDS_ANY_FILE - Don't touch verb keys that are not edited to retain the original REG type - Don't clobber unchanged %1 icon location when editing a type CORE-19756
