Must kill biotouch.exe !!

[Fua]

I'm not entirely sure what Biotouch.exe does and from reading the forums it seems like I could do without it and save some battery life.
I'm using MightyRom4 and I can see biotouch.exe running in the task manager (windows\taskmgr.exe), but the task manager doesn't allow closing of processes.

So two questions:
1) Is there a way to prevent biotouch from running? (I already removed it from the startup folder)

2) Is there a way to kill processes from MightyRom's task manager?

Thanks for help/advice.
