Office Web Apps services include companions to Microsoft Word 2010, Microsoft Excel 2010, Microsoft PowerPoint 2010, and Microsoft OneNote 2010. These would be available on Windows Live at no cost to users as an ad-supported service (read: Office Web Apps Coming to Windows Live). For enterprise users, it can be hosted on SharePoint 2010 (SharePoint Foundation 2010 or the SharePoint Server 2010) either on-premise or online.

Office Web Applications are licensed with Office 2010 and need to be installed and enabled on top of SharePoint 2010. These applications are focused on offering access to Word 2010, PowerPoint 2010, Excel 2010, and OneNote 2010 documents through any browser across multiple platforms, lightweight creation and editing capabilities in standard formats. When enabled, it enhances experience of SharePoint user. For example,
  • When user clicks on an Office document in a Document Library it will launch the Office Web App viewer
  • When user clicks ‘New Document’ in a Document Library to create a new Office document but does not have the respective desktop application, Office Web Application will be launched to author the document
