The Windows 7 engineering team utilized the feedback they would get each and every time someone would submit it and it works as ARS Technica reports:
The fact that we now are pretty much tied to the internet all the time (our computers are, not us personally-at least not yet), should also mean your computer can stay optimized all the time instead of waiting until you know you have a problem. This is where the times are changing. You shouldn't have a fast, clean, efficient computer experience only right after the computer tech has cleaned it, not when your technician can help you remotely... are you taking advantage of this service? You should be!
