Just open Word and then press F1.
Here's what it says:

Convert several documents at once:

Place the documents you want to convert in a single folder.

On the File menu, click New, and then click the Other Documents tab.

Double-click Batch Conversion Wizard.
Note If you do not see the Batch Conversion Wizard in the New dialog box, you may need to install it.

Follow the directions on the screen.

Hope this helps.
