I was delighted to find this old gem about keeping your Windows system running virtually forever without fear of resource hogging. I used to think that, no matter what you do (or try your hardest not to do), Windows will always slow down in due time because of the DLL and registry access/writing. Well, that may still be true today, but at least you can keep it from happening at a faster rate.
To over-generalize and sum up the article in one sentence: pay attention to an entry called “Handles” in the Task Manager; keep the number below 12,000 by shutting down services that uses them the most, and you’ll be just fine.
That’s good software writing. It’s succint, easy to skim/read/try and practical.
