Mac Changing Default Starting App

In Windows on your Mac, click in the right side of the taskbar, click the Boot Camp icon, then choose Boot Camp Control Panel. If a User Account Control dialog appears, click Yes. Select the startup disk that has the default operating system you want to use. If you want to start up using the default operating system now, click Restart.

Certain actions that you perform on your Mac will cause default apps to open. For example, clicking a document may open Pages. But what if you want Microsoft Word to open instead? You can also set your default web browser and email reader.
