Services are background processes which keep running waiting for a response, so if you don’t use the application it still runs and slows PC speed. The average user doesn’t need many running.

1. Click the Start button
2. Type msconfig in the Start Search box, hit enter
3. Click the Services tab
4. Uncheck the unneeded startup items (examples below)
   Desktop

Offline Files - The Offline Files service performs maintenance
activities on the Offline Files cache. Uncheck to disable.

Terminal Services - Allows users to connect interactively to a remote computer. Remote Desktop and Terminal Server depend on this service. If you don’t use either of these, then you can disable the service. Uncheck to disable.

Windows Error Reporting Service - Allows errors to be reported when programs stop working or responding and allows existing solutions to be delivered. Uncheck to disable.

After you are finished, click Apply then click OK to save changes.
