Choose page numbers only when the headings are unchanged; choose the entire table when heading text or structure has changed
Use a report-purpose–heading-style–heading-text–heading-level–page-flow–automatic-or-manual-TOC–update-choice–field-result–cross-reference–link–layout–PDF-export–upload chain. Decide from the document change, not from habit, then inspect every entry that a reader will use to navigate.
Why this English matters now
Reading Word’s Update Table of Contents choice before submitting a long report is practical English for students, researchers and professionals searching how to update a table of contents in Word, fix missing headings or refresh page numbers.
Microsoft’s current guidance says Update page numbers only changes the pages on which existing headings appear and ignores heading-text changes. Update entire table reflects heading-text updates as well as page changes; Microsoft also notes that a manually typed table of contents cannot be updated automatically from headings.
The correct button depends on what changed. Strong writers use heading styles deliberately, preserve the document, choose the narrower or broader update with evidence, inspect levels, links and fields, then export and open the exact PDF or uploaded file before submission.

The practical reading method
Use a report-purpose–heading-style–heading-text–heading-level–page-flow–automatic-or-manual-TOC–update-choice–field-result–cross-reference–link–layout–PDF-export–upload chain. Decide from the document change, not from habit, then inspect every entry that a reader will use to navigate.
- Microsoft says Update page numbers only updates the pages of existing headings and ignores heading-text changes.
- Microsoft says Update entire table reflects heading-text updates and page changes.
- Microsoft says manually created tables of contents cannot be updated automatically by Word.
- A refreshed table of contents does not prove heading levels, wording, cross-references or PDF navigation are correct.
Official factual floor
- Microsoft Support: Update a table of contents
- Microsoft Support: Update fields
- Microsoft Support: Format or customize a table of contents

- Microsoft says Update page numbers only changes page references for existing sections and does not add new sections or heading-text changes.
- Microsoft says Update entire table includes heading-text updates and page changes.
- Microsoft says a manually created table of contents must be edited manually rather than updated from document headings.
Did You Know?
A heading can move to a different page without changing its words, while another heading can keep the same page but change its words. Word therefore offers two update scopes because pagination and document structure are not the same problem.
Full chapter index
- 1. Define the report and submission route
- 2. Preserve the source before field updates
- 3. Confirm the TOC is automatic
- 4. Inspect heading styles
- 5. Compare heading text with entries
- 6. Choose page numbers only narrowly
- 7. Choose the entire table for structural changes
- 8. Check added, deleted and reordered sections
- 9. Inspect levels and indentation
- 10. Update other fields separately
- 11. Check layout after pagination changes
- 12. Test hyperlinks and PDF navigation
- 13. Verify the exact submission
The mechanism
The final format determines what navigation and pagination must be checked.
Microsoft says Update page numbers only updates the pages of existing headings and ignores heading-text changes. In this chapter, the decisive phrase is define the report and submission route. It identifies the state or boundary to check before a click, upload, disclosure or connection turns an assumption into a real consequence.
A practical school or study situation
Example: A Word TOC is updated without knowing whether the assessor will read DOCX, PDF or print.
The update dialog controls how Word refreshes the table-of-contents field. It does not prove all headings use the correct styles, custom levels are right, manual text is preserved, other fields are current, page breaks are intentional or the exported PDF matches the source.
- 1. read the brief
- 2. name the final format
- 3. record page and heading rules
- 4. identify the accountable submitter
Preserve the source; confirm the table is automatic; show heading styles and navigation structure; compare headings with TOC entries; decide whether only pagination changed or heading text and structure changed; run the appropriate update; inspect levels, indentation, dot leaders, page numbers and hyperlinks; update other fields separately; export the required format; open the PDF and test navigation; compare the actual upload with the approved Word file. Then name the remaining uncertainty. A successful click is evidence about one operation at one time; it is not an unlimited promise about safety, authorship, privacy, delivery or future behaviour.

The mechanism
Field refreshes can alter many entries at once.
Microsoft says Update entire table reflects heading-text updates and page changes. In this chapter, the decisive phrase is preserve the source before field updates. It identifies the state or boundary to check before a click, upload, disclosure or connection turns an assumption into a real consequence.

Example: The only thesis copy is updated after headings were manually edited inside the TOC.

Microsoft says manually created tables of contents cannot be updated automatically by Word. In this chapter, the decisive phrase is confirm the toc is automatic.

Four useful discoveries
Define the report and submission route
The final format determines what navigation and pagination must be checked.
Boundary: One assignment may require several output formats.
Preserve the source before field updates
Field refreshes can alter many entries at once.
Boundary: Backups still need privacy and access control.
Confirm the TOC is automatic
Microsoft distinguishes heading-derived tables from manually typed lists.
Boundary: A custom automatic TOC can still contain manual-looking formatting.
Inspect heading styles
Automatic TOCs normally depend on headings and configured levels.
Boundary: Custom styles may be mapped deliberately into a TOC.
Practice with realistic decisions
Compare heading text with entries
A chapter is renamed in the report but the old name remains in the contents page.
- read headings in Navigation Pane
- compare each TOC entry
- mark renamed sections
- check punctuation and numbering
Choose page numbers only narrowly
It is chosen after a new subsection is added, so the subsection stays absent.
- confirm no heading was added
- confirm no heading was deleted
- confirm no heading text changed
- then update page numbers
Choose the entire table for structural changes
A revised title remains stale because only page numbers were refreshed.
- list changed headings
- choose Update entire table
- review every changed entry
- restore justified custom formatting if needed
Advice for students, families and educators
For students
- Use page numbers only only after proving that no heading text or structure changed.
- Follow links in the final PDF, not just in Word.
For families
- Read the TOC as a first-time reader and compare it with visible chapter headings.
- Let the student make editorial decisions and record the final version.
For educators
- State whether the submitted DOCX, PDF or both are assessed.
- Teach heading styles as document structure, not merely font formatting.
Frequently asked questions
What does Update page numbers only do?
It refreshes pages for existing headings and ignores heading-text changes.
What does Update entire table do?
It includes heading-text updates and page changes.
Which should I choose after adding a heading?
Update the entire table.
Which after only repagination?
Page numbers only may be suitable after confirming headings are unchanged.
Why is a heading missing?
Check its style, level and TOC configuration.
Can a manual TOC update automatically?
Microsoft says no.
Does updating the TOC update every field?
Do not assume so; update and inspect other fields separately.
Will PDF links work?
Verify the chosen export and viewer.
What should I verify?
TOC type, headings, update scope, levels, fields, links, PDF and exact upload.
Why English?
Because page number, heading text, level, field, link, export and upload describe different document states.

Closing thought
A table of contents is a reader’s map. Refresh the part that actually changed, then read the map from top to bottom and follow its links in the final file before asking anyone else to rely on it.
