Add Tabs to Microsoft Office
This is another great MS Office utility mentioned in Lifehacker. One of the few necessary features missing from Microsoft Office is the ability to view documents, spreadsheets, etc., in tab view like you do in a web browser. It is called OfficeTab. It is helpful when you have more than one Office document open at a time (which for me is almost always). Download it here. I installed it on my desktop PC with Office 2007. It works as promised.
