Unified Communications How-To
The Microsoft Unified Communications “How-To” training tool is a Microsoft Silverlight™ 2 application that provides step-by-step instructions for common UC tasks. You can customize the How-To application to your company’s needs based on the UC features you’ve installed. For example, if you have installed all UC features except Communicator Mobile and Communicator Group Chat, you can modify the XML file so that those features and topics do not appear in the interface.
