How to set the default font in Word

ISSUE
I want to create new documents that have the font(s) already configured
so I don't have to always change font, size, colour, OpenType features every time.

SOLUTION
Format the style of the default font in Word 2010 as a Template document,
then base new documents on that.

Here's how to do it:

Create a new Template document by choosing File > New > My Templates
Click Create New.

In the Font group panel, click the Font flyout icon.
Select options you want to apply to the default font, such as font style and font size OpenType features.

If you selected specific text, the properties of the selected text are set in the dialog box.
Click Set As Default button.

If blank text document is needed, just delete any text in the document. The attributes will remain.

Select the option for All documents based on the Template 1 ?, then click OK.

To create a new document based on the Template, click File > New from existing
and navigate/choose the Template required.

When saving the newly created document from the Template,
don't just 'Save' because that will save the Template with the changes you just made!

Instead, choose File > 'Save As' and from the Save as type dropdown choose Word document.
Give the document a File name.

You have now created a new document based on the Template, but with your changes in it.
You can now continue to make changes to this document and just 'Save' it.
Because this is a different file, the original Template is not affected.
