Downloaded it and began using it yesterday.
First off, once you see how to use it, it's not too difficult. Allow your cursor to scroll over the "Services" and "Programs." The program will give you a description of the program and advise whether to take "No action" or turn it off. I always select "Stop and Return." Once complete, you need to select which .exe (AH executable), you want this profile to work for, then save.
Now, instead of just starting AH, you open FSautostart and hit "Start." The program will then begin shutting down all of your unnecessary programs and then launch AH. Once done with AH, the program restarts all of your programs and services.
I've noticed a substantial increase in frame rates (maybe 33%) and a lot less misses when I actually line up a shot. Don't worry, I still suck, just at a reduced level...
