Default Behavior

Browser Support Driver is a file system driver. In Windows 10 it is starting only if the user, an application or another service starts it. If Browser Support Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the bowser service has failed to start due to the error.


While Browser Support Driver is stopped, the Workstation service cannot be launched.
