Best way to stop simulation solver once it starts

I'm am at my whits end with simulation. Long story short whats the fastest way to stop simulation and kill it onces it starts solving.  I waste so much of my day rebooting my machine.  Cancel solver is a complete waste, shutting down SW only works some of the time, and I can't seem to find the program name when i hit ctrl+alt+delete.
