Uninstalling ActiveX Controls

If any ActiveX controls that have been downloaded to a user's machine are no longer needed, you can uninstall them by removing them from the Downloaded Program Files directory.

If the user has permissions as described in Modifying User Groups or Permissions, applicable controls are downloaded again as they are needed.
