Hi there! I can definitely help you with changing the default formatting for footnotes and endnotes in Word 2007. Here are the steps:

1. Open a new or existing Word document.
2. Click on the "References" tab in the Ribbon at the top of the screen.
3. In the "Footnotes" section, click on the small arrow in the bottom right corner to open the "Footnote and Endnote" dialog box.
4. In the "Footnote and Endnote" dialog box, click on the "Footnote" or "Endnote" tab, depending on which one you want to change.
5. Make the desired changes to the formatting options, such as font size and indentation.
6. Click on the "Set As Default" button at the bottom of the dialog box.
7. In the "Normal.dotm" template dialog box that appears, click on the "OK" button to confirm the changes.

That's it! Now, all new footnotes or endnotes you create in any Word document will have the formatting options you just set as default. Note that this will not affect any existing footnotes or endnotes in your document, but you can easily reformat them individually as needed.
