Turn off track changes
When you’re done tracking changes, turn change tracking off—but that doesn’t remove all the marked changes that are already in your document. It’s a two-step process: Turn off Track Changes, and then accept or reject the changes. After those two steps, you have a clean document that’s ready for the world.
You turn Track Changes off the same way you turn it on:
Click Review > Track Changes.
Now it’s time to clean up any markup left in your document.
Remove tracked changes
The only way to remove tracked changes in a document is to accept or reject them.
Click Review > Next > Accept or Reject.
Word accepts the change or removes it and then moves to the next change. To accept all the changes at the same time, click the arrow by Accept and click Accept All Changes.
To remove comments from your document, delete them. Click the comment and then click Review > Delete Comment.
Or click Review, click the arrow by Delete Comment, and click Delete All Comments in Document.
