A Windows service starts when Windows is booted and runs in the background as long as you are working on your PC.There are many services that run when you start your PC. With my experience with Windows and it’s tools, I have found out some of the services that can be disabled and your PC would still run fine.

First of all, you have to know the place from where you can view, enable/disable the services. Go to Start > Run and type msconfig. Now click on the Services tab. That’s it. You could now see a number of services.

Below is a list of services that can be disabled. Just see the service name from here and scroll down in the Services window, un-check the service and done!

Remember: If you use any of the following services, then don’t disable that one. It would cause your application (or whatever it is) to stop working.
Disable the following services:

• Alerter
• Application Management
• Clipbook
• Fast UserSwitching
• Indexing Service
• Messenger
• Net Logon
• NetMeeting
• QOS RSVP
• Remote Desktop Help Session Manager
• Remote Registry
• Routing & Remote Access
• SSDP Discovery Service
• Universal Plug and Play Device Host
• Web Client

Some service names may vary. I’m again telling you, do it at your own risk. If at anytime after disabling them, you find that your applications are not behaving as they should be, then enable them back. And make sure you always make a backup of your Windows settings before trying these tweaks and tricks.
