There are lots of little programs used by the Windows operating system that take up memory, waste disk space and CPU clock cycles. These programs are called “services” and include all kinds of things such as UPS support, Netmeeting, QoS packet scheduler, telnet, themes, and alot of other obscure things that the average user doesn’t need.
Some of these services use more resources than others, so one of the safest and best tweaks you can perform to your Windows PC is to disable some of the unnecessary services that are installed by default. Some of these services are huge security risks, too, so it’s worth going through this list to see what you really need and don’t need running on your PC.
However, now comes the hard part. What services are unnecessary? Some are very necessary, so you can’t just go around arbitrarily turning off services. The next section describes what each of these services are, with a description of that they do, and a recommendation whether to Disable it.
First, you should open up a window that allows you to see the services. You can do this in one of two ways:
What you’ll need to do is right-click (or double-click) on the appropriate service, go to properties, and then alter the “startup type” to either automatic (starts at boot), manual (starts if windows needs it) or disabled (never starts). A rule to use here is, if you definetely don’t need it, Disable it. If you don’t know for sure, but think you don’t need it, set it to manual.
Also…don’t do all the services at once. Tweak a couple, then reboot and make sure your computer still functions fully. If it doesn’t, go turn the services back on. If it does, continue on. If you’ve ever overclocked a processor or a video card, then you’re probably familiar with the process. Only small tweaks at a time, then test, then some more tweaking. That is the only safe way to overclock (or disable system services).
