Earlier this week I was formatting a lengthy training manual in Word and wanted to number the table of contents and introduction with i, ii, iii, but needed 1, 2, 3 numbering for the rest of the document.  I thought this might be something of interest to others needing the same flexibility so have noted the process below.

1. Click at the beginning of the page where you want to start, stop, or change the header, footer, or page numbering.
2. On the Page Layout tab, in the Page Setup group, click Breaks.
3. Under Section Breaks, click Next Page.
4. On the page that follows the section break, double-click in the header area or the footer area (near the top of the page or near the bottom of the page).
   This opens the Design tab under Header & Footer Tools.
5. On the Design tab, in the Navigation group, click Link to Previous to turn it off. IMPORTANT: If your page number is in the header/footer, be sure that you turn off linking for headers/footers. Headers and footers are linked or unlinked separately.
6. Follow the instructions for adding a page number or for adding a header and footer with a page number.
7. To choose a numbering format or the starting number, click Page Number in the Header & Footer group, click Format Page Numbers, click the format that you want and the Start at number that you want to use, and then click OK.
8. To return to the body of your document, click Close Header and Footer on the Design tab (under Header & Footer Tools).
