Prevent the formatting of a Word document from being accidentally modified

Many Word documents have a fixed format, so that we can protect the formatting of Word documents to avoid changes in order to avoid the misuse of the document.

Open the Word document you want to protect, click the Tools menu, select Protect Document, and then open the Action window on the right.

Select the Restrict formatting to options style item, and click the Settings button to select all the formatting you want to protect in the open formatting Restrictions window, such as preventing changes to headers, footers, and so on, returning to protect documents, and clicking Yes, start the Force Protection button. Set a password in the pop-up window to make the settings effective.
