Ghacks posted a tutorial about increasing Windows 7 performance in 4 easy steps

Even if you’ve just bought a brand new computer complete with Windows 7, you may find you’re lacking some power. Most new computers are pretty quick these days, but they are usually set to some default settings that can be tweaked to give you more power for nothing. These tips aim to show you a few easy to change settings that will release some extra power and speed up your computer without having to install anything.

Click on your start menu and type the words “ease of use” into the search box, and then press return. You will find a section called Ease of Access Center. In this area scroll all the way down to the bottom and find a section called “Make it easier to focus on Tasks”. Click on this you’ll be taken a new screen. Go to the bottom of this screen and find the section called “Make it easier to manage windows”. Uncheck the box that prevents windows from being automatically arranged when moved to the edge. This will give you a small increase in performance.
