Default Behavior

Bcmfn2 Service is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it. If Bcmfn2 Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the bcmfn2 service has failed to start due to the error.

Restore Default Startup Configuration for Bcmfn2 Service

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

3. Close the command window and restart the computer.

The bcmfn2 service is using the bcmfn2.sys file that is located in the %WinDir%\System32\drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
