This feature works the same in all modern versions of Microsoft PowerPoint: 2010, 2013, and 2016. If you would like to track changes in a presentation, you should have the reviewer review a working copy of the presentation and then compare the two presentations. Unlike Word, PowerPoint does not provide a Track Changes reviewing option. How to Track Changes in Microsoft PowerPoint See Microsoft PowerPoint: Tips and Tricks for similar articles.
