MS Word: "... should be opened as read-only unless changes to it need to be saved. Open as read-only?"

I got this message when opening a Word document, which I just cleansed with the Hidden Data Removal tool from Microsoft.  Not sure why it'd flag the file so, but it apparently did.  Here's how to correct it (sourced from this thread):

1. Open the file - make sure not in Read-only mode
   
2. On Tools menu, click Options. 
3. Click Security. 
4. De-select the "Read-only recommended" check box, and then click OK. 
5. Click Save.
