How to Lock Text in Word 2007

Lock Everything with Read-Only
1. Start Microsoft Word 2007 and open the document you wish to lock.

3. Select the 'Review' tab and click on the 'Protect Document' button. Click on 'Restrict format and editing.'
4. In the section marked 'Editing Restrictions,' check the box labeled, 'Allow only this type of editing in the document.'
5. In the drop-down menu, select 'No Changes (Read Only)' and click 'OK' to save the changes. Other users who open a document with this option turned on will receive a read-only notification, and cannot make any changes to the file unless they save a separate copy.
Lock Portions of Text

7. Click and drag to highlight the section of text you wish to lock.
