Explanation:
Configure the default open behavior for documents
In SharePoint, you can configure whether browser-enabled documents are opened in a client application or in the browser. By default, when Office Web Apps is installed, Office documents will open in the browser. You can override this setting using the SharePoint OpenInClient feature. The OpenInClient feature can be configured in Central Administration or by using the SPFeature cmdlet in Windows PowerShell.How documents open in SharePoint varies depending on whether the OpenInClient feature is present, and either enabled or disabled:
* If the OpenInClient feature is not present and Office Web Apps is not installed, documents will open in the client application (SharePoint default).
* If the OpenInClient feature is not present, Office Web Apps is installed and Office Web Apps service applications are activated, documents will open in the browser (Office Web Apps default).
* If the OpenInClient Feature is present and enabled, and Office Web Apps service applications are activated, documents will open in the client application.
* If the OpenInClient Feature is present and disabled, and Office Web Apps service applications are activated, documents in will open in the browser.Source: http://technet.microsoft.com/en-us/library/ee837425.aspx
