Default Behavior

Browser Support Driver is a file system driver. In Windows 7 it won't be started if the user doesn't start it. If Browser Support Driver fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the bowser service is not running because of the error.


If Browser Support Driver is stopped, the Workstation service fails to start and initialize.
