On the top of MS Word you'll find the menu bar. Click on 'View' and then 'Header and Footer.' What appears is a dotted box already with a cursor inside. A floating menu bar also appears.
Moreover, you can also use Word templates for letterheads, invoices and even for monthly business reports. This is because it is integrated with other Microsoft Office programs such as excel. This way, you can import graphs and other objects necessary for completing a well formatted report. There really is a long list of uses for Microsoft Word. You will certainly find it useful whether you are a student, a professor, a businessman, a home maker or whoever you are from whatever industry.
