Microsoft SharedView lets you collaborate with up to 15 people and share the desktop or individual application windows in the host computer with other users. Let’s assume you have a detailed action plan for your company stored in a word document, and you need to share the document with your fellow staffs so that they can do their modifications to the original document simultaneously, SharedView should suffice your needs. Further, if you have Track Changes feature enabled in Microsoft Word, each change made to the content of the Word document by a participant can be identified with the participant’s name with the timestamp when the change was made. The host can then review the modified document, and accept or reject each change.
All you need is a Windows Live ID to start or join a session in SharedView.
Start SharedView, sign in using your Windows Live ID, and then start a new session.
