Everyone tries to get as much performance out of Microsoft Windows as possible. Whether it’s gaming, or 3d applications, we can always wish our computers were faster. Windows is a resource intensive operating system, taking much more of your available resources then are needed. Windows is designed to pretty much find any new hardware, or any possibility of hardware you may have in your computer. Since windows tries to be everything for everyone, there are many services running by default that we just don’t need. Here is a site that shows in detail each service running for your version of windows, from XP to Windows 8.1.

It breaks down each and every service that windows is running, and gives a small example of what the service does, if it needs to be started, and if it should be manually, delayed, disabled, or automatically started.
