How to Disable Unnecessary Services in Windows Vista

By Dan Gookin

A service is something a program does in Windows — specifically, a program that starts automatically whenever the computer starts. Most services are things that Windows does, and most of those services are tasks that you don’t need to have running in your computer.

To disable a service, follow these steps:

  1. Open the Control Panel.

  2. Choose Security and then choose Administrative Tools.

  3. Open the Services icon.

  4. Click the Continue button or type the administrator’s password.

  5. Locate a service to disable.

    Use the list at the end to help you decide which services to disable.

    Click the Name column heading to ensure that the services are sorted alphabetically.

  6. Double-click the service to open its Properties dialog box.

  7. Choose Disabled as the Startup type.

    By choosing Disabled, you prevent the process from starting when the computer starts.

    Make a note of the service’s original state: Automatic or Manual. Just in case you need to re-enable the service, you should know how it was configured before you changed it.

  8. Click OK to confirm your choice and close the dialog box.

    When you’re concerned about compatibility, or that your computer may work improperly after disabling a service, restart Windows. When the system starts up, try it out for a while to ensure that things are working well. Then continue or, if there’s a problem, re-enable the service to Automatic or Manual or whatever the previous setting was.

  9. Repeat Steps 4 through 7 as necessary.

  10. Close the Services window when you’re done.

    You can also, optionally, close the Control Panel window.

Here’s a list of services that you might be able disable to help improve your computer’s performance.
