Problem: Compare Button Is Grayed Out

1. Check if the current document is protected:
   • Go to Review > Restrict Editing
   • Click Stop Protection (you may need a password)
2. Make sure both documents are .docx format
3. Close all other documents except one, then try Review > Compare

Problem: Compare Produces Errors or Crashes

This happens with very large or complex documents:

1. Save both documents as .docx if they’re in other formats
2. Remove any document protection from both files
3. Try comparing smaller sections: copy parts to new documents and compare those
4. Disable add-ins that might interfere (start Word in Safe Mode)

Problem: Compare Results Are Inaccurate

1. Go to Review > Compare > Compare Documents
2. Click the More button to expand options
3. Check or uncheck comparison options:
   • Comments, Case changes, Whitespace, Tables, Headers/Footers, etc.
4. Choose comparison granularity: Word level vs Character level

How to Use Compare Correctly

1. Go to Review > Compare > Compare Documents
2. Browse to the Original document and the Revised document
3. Choose where to show changes (New document recommended)
4. Click OK
5. Review all changes in the resulting comparison document
6. Accept or reject each change individually
