I have two .bat files on my desktop for when I game. One shuts down both FAH services, the other starts them back up again. Thus, when I need full use of my rig to frag some people, I just click the "Stop FAH" .bat file and when I'm done with my killing (or being killed) spree I hit the "Start FAH" .bat file.
Copy/paste the following into two bat files:
****Stop FAH, copy between the asterik lines******
sc stop FAH1
pause 1500
sc stop FAH2
**********************************
*****Start FAH, copy between *********
sc start FAH1
sc start FAH2
***********************
Just in case, a batch file is simply some command line in a notepad doc that you save as "some-name-here.bat" instead of "some-name-here.txt". So just open notepad, copy/paste the first .bat, and save it as "Stop-FAH.bat". Then repeat for the second one naming it "Start-FAH.bat".
