Disable a feature
If a feature has been enabled, the Disable button will appear in the details pane. You can use this button to disable the feature. The Disable button isn't available if the feature can't be disabled.
After a feature is disabled, a message will appear below the Learn more link in the details pane. This message states that the feature hasn't been enabled, and it will appear whenever you select the feature in the feature list. Features that haven't been enabled will appear on the Not enabled tab.
