The Window Services quick link is a shortcut that will open the Window Services application. In this window is a list of all the services that are running on windows. This is very useful as a quick link because you can restart the enterprise server here.
The enterprise server is needed for EASYProcess to run and sometimes could become overloaded if a processes or webparts are taking very long to load due to an error or bad database connection. This is when restarting the enterprise server would be necessary and can be easily accessed through this link.
