Getting rid of processes is not a matter of just arbitrarily shutting things down. If you do not know what you are doing you can do more damage to the system than good.
Typically your system should not be running any more than 28-33 processes at Windows boot and the processes that are running are essential and not memory/cpu killers.
In order to figure out what needs to stay and what needs to go it requires a professional go through the startup system and from experience make the call to delete registry startup lines as demonstrated here:

In any case, part of getting a system running correctly for graphics performance is cleaning the startup system and making sure your processes list is reasonable.
People running 40+ processes at Windows boot can expect FSX slowdowns, low performance and stutters. I have seen some try to run FSX with add-ons who have a process list that would choke an elephant to death
