4) Now open properties for that service and goto "Log On" tab.
5) Change selection to "This Account" and browse the user account that you want to support for your service. In my case i selected Administrator.
6) Enter the appropriate password and apply the changes.
7) You may require to restart your Service to get the changes applied.

The Exception is,
