Changing a Service from the "Default" to "Something else."
Start --> Control Panel -->
Performance and Maintenance -->
Administrator Tools -->
Services -->
Select "Any Service" -->
(Double Click)
Select "Automatic, Manual or Disabled."
After configuring all services, reboot to see the effects of your tweaking.
Note: Do not use msconfig to stop services. It basically is "disabling" a service. Use the above procedure and set to "manual" instead for testing purposes.
If you like, you can also do: Start --> Run --> type in services.msc --> Select OK.
