Word lets you track any changes that are made to a document. However, if an individual accepts the changes they have made, you cannot easily see those changes were. To ensure that you are able to review changes before they are accepted, you can prevent others from being able to accept changes without knowing the appropriate password.

To prevent changes from being accepted in Word 2007:

1. Display the Review tab of the ribbon.
2. Click the Protect Document tool within the Protect group. Word displays the Protect Document pane at the right side of your document.
3. In the Editing Restrictions section of the pane, choose the Allow Only This Type of Editing In the Document checkbox. Word enables the drop-down list under the checkbox.
4. Using the drop-down list, choose Tracked Changes.
5. Click Yes, Start Enforcing Protection. Word displays the Start Enforcing Protection dialog box.
6. Enter a password (twice) in the dialog box.
7. Click on OK.
8. Save the file.
