How to unlock a word document

1. Open your document in Word, then use "Save as..." to save it in ".xml" format. 
2. Open the .xml file in wordpad, notepad, emacs, or other text editor of your choice. 
3. Search for the string w:enforcement="1" (or w:enforcement="on"). 
4. Replace the "1" with a "0" (or replace "on" with "off") to disable enforcement. (This step unlocks the document.) 
5. Save the .xml document from your text editor. 
6. Open the .xml document in Word. 
7. Choose "Save as..." and save it as a .doc or .docx file. 
   Your original Word document can now be edited normally. Enjoy!
