What is/are the purpose(s) of the following services of Windows Vista? What is/are 
their effect(s) when unchecked, disabled, or not running or what consequences will 
I be facing when I disable one or more of them? This can be seen under "System configuration 
utility" (Start > In search text box, type "msconfig.exe" > Click "Continue" only 
when prompted for permission from you for launching "System configuration utility" 
> Tab "Services"). If there any other services of Windows Vista, please let me know. 
Thank you.
