IIS 7.5 - Change Application Pool Start Mode to Always Running

I have IIS 7.5 and I have installed the Application Initialization Module for it. Now, I am trying to change the StartMode of an application pool, but do not see the StartMode option in the IIS Manager. I have looked under Basic and Advanced Settings. I am thinking that the next place to edit this value would be in the Machine.Config. So, I have found that file, but I am unsure where the update would be placed in there. I believe it should be set to AlwaysRunning.

Any help would be appreciated.

How do I change the default application pool in IIS 7?

In the Connections pane, expand the server name, and then click Application Pools. In the Actions pane, click Set Application Pool Defaults... On the Application Pool Defaults dialog box, specify your desired options. When you have finished specifying your settings, click OK.

I found the Configuration Editor under the Management section of the IIS manager.

EDIT: startMode is in section system.applicationHost/applicationPools under applicationPoolDefaults. It can also be configured on a per-item basis in Application Pools - Advanced Settings.
