How to Unprotect a Word Doc
Microsoft Word 2010 contains a document-protection feature that you can enable to limit the changes that other people can make to the file. The protection is enabled with a password, so in order to unprotect a document, you will need to know the password with which the document protection was initially set. You can ascertain whether a document is protected or not by looking at the Restrict Editing icon, which is a piece of paper with a dog-eared corner, under the Protect group; if a lock appears next to the page image, then the file is locked for editing.
Click the "Review" tab at the top of the screen.
Click "Restrict Editing" in the Protect group.
Click the "Stop Protection" button that appears within the Restrict Formatting and Editing window.
Enter the password in the blank field in the Unprotect Document dialog box that opens. Click "OK."
