Disable unnecessary services to free system resources

Published in Windows XP Performance Tweaks by Steve Sinchak with 74,112 views

Services are programs that run when the computer starts up and continue to run as they aid the operating system in functionality.  There are many services that load and are not needed which take up memory space and CPU time.  Disabling these services will free up system resources which will speed up your overall computer experience.  I  recommend that you sort through the list and read the descriptions to decide if you need that service depending on what you want to do with your computer.  Remember, you can always turn the service back on if you find that you need it in the future. Below is the procedure to turn off a service.

  1. Click the start button.
  2. Select run from the bottom of the right column.
  3. Then type services.msc in the box and click ok.
  4. Once the services window has loaded we are ready to turn off unneeded services.
  5. For instructional purposes we are going to turn off the Portable Media Serial Number service.
  6. Find this service in the list and select it with the mouse.
  7. Right click and select Properties.
  8. Once the properties windows has loaded locate the Start up type drop down box and select disable.
  9. Then just click ok and the next time the computer starts the service will not be loaded.

The potential problems of disabling services far outweigh the possible benefits. The descriptions in the services control panel applet are incomplete, many do more than is stated. Even experts have got themselves into trouble with this.

Controlled tests have failed to uphold the claim that disabling services will significantly improve performance. Unless you are very short on memory the gains will be unmeasureable.

Hi Larry,

I disagree that there is no benefit to disabling services. An advanced user that knows how to troubleshoot properly if they encounter issues can obtain measurable results. Something as simple as disabling an indexing service on a netbook has an impact on performance. Sure, its not a 50% improvement but its a little given they are willing to give up the benefits of the service they disabled. In some use cases there may be extra services that are just taking up memory such as the bluetooth service or the portable media serial number service on a virtual machine that has absolutely no use for those services since those devices will never be connected. In large enterprises with thousands of XP virtual machines it is absolutely critical to minimize the footprint as much as possible so you can optimize VM ratios. This is even more important when you consider all the junk services that get installed by third party applications such as auto update daemons that are not needed in a highly managed enterprise environment. If you could cut the memory footprint by 25 MB on each VM running on one host that has 20 VMs you will free up enough memory to add another 512 MB Ram XP VM to that host.

Larry, you make it sound like it's dangerous to disable services. With the exception of antivirus and firewall services, there's nothing at stake. If you disable a service and don't like the result you can just enable it again. At worst, you need to boot in safe mode to do it.
