Sometimes, when we do online research for projects, we tend to copy the contents of the site(i.e. wikipedia) and paste it to MS Word. That's what most students do today, copy+paste then print and submit to the teacher.
But if you'll notice, when copying, the hyperlinks will also be copied to the document making the words color blue and opens your browser once you click on them. Here's a simple way to remove all of the hyperlinks at once.
1. Select the whole document(CTRL+A)
2. Press CTRL+SHIFT+F9
All the hyperlinks will then be removed.
