To remove page numbers from certain pages in Microsoft Word, the process generally involves breaking the document into sections and unlinking the headers or footers between these sections so that page numbers can be independently controlled. Here is a summarized step-by-step guide:

1. Insert Section Breaks:
   • Place your cursor at the beginning of the page where you want the page numbering to change or stop.
   • Go to the "Layout" tab, click "Breaks," and select "Next Page" under Section Breaks.
2. Unlink Headers/Footers:
   • Double-click the header or footer area on the page where the new section starts.
   • In the "Header & Footer" tab, click "Link to Previous" to unlink it from the previous section. This allows changes to be made independently.
3. Remove Page Numbers from Certain Pages:
   • Navigate to the header or footer of the section from which you want to remove the page numbers.
   • Select the page number and delete it. Because the sections are unlinked, the page numbers in other sections will remain.
4. Repeat as Needed:
   • Repeat the process if you want different page numbering setups in other parts of the document.

Additionally, for removing page numbers only from the first page, use the "Different First Page" option in the header/footer "Design" tab. This approach helps control page numbers in different parts of your Word document flexibly without affecting other pages.
