For a chess program to get maximum speed, it would have to BE the operating system (so it owns the process(s) 100%), and when you look at these numbers I posted, you would get a few extra minutes every 6 hours, or something like a 2% speed up, which is worth nothing in practical play. Actually, you wouldn't even get that much of a speed increase, becase the "few extra minutes" were not Windows, but applications, such as Internet Explorer, MSVC++, Windows Explorer. "System time" is 23 seconds out of 6 hours and 50 minutes (now). So if your chess program ran for 7 hours, it might get an extra 30 seconds of search time, and that is absolutely worthless. That comes out to a 0.1% speed increase.
