I found this
, which has both an x64 version and x86, and I downloaded it to test it out. You have to change the settings to log all executed processes, which is in Options -> Log Settings, and then you can set it to remember more lines in the log (default is 100). I am still not sure if this is exactly what you are looking for, but it seemed to work for me. Let me know if you have any issues with it or if it doesn't do what you need it to do. It was only using about 3 or 4 percent of my CPU.
