How do I track changes in Powerpoint?
From http://www.microsofttraining.net/post-30554-powerpoint-compare-tracked-chang.html
You can make track changes in PPT 2010 but not in 2007.
Suppose you have 2 presentations PPT A and PPT B where changes have been made in PPT B.
- Open PPT A and select Review tab, Compare.
- Select and open PPT B.
- The changes appear as Markup and a Reviewing pane appears on the right of the screen displaying PPT B as a slide or you can see the detailed changes.
You can also hover over the pencils to see what's changed. The Next and Previous buttons are like in Word where you can navigate to each change and accept or decline the change or accept/decline all changes.
In PPT 2007 you can only track inserted comments rather than compare any changes between 2 presentations.
This http://geigercomputers.com/track-changes-in-word-and-powerpoint/ also has similar answer but in more details.
That depends somewhat on which version of PPT you have, but no version has anything like the tools Word does.
Basically, it boils down to users adding comments to a PPT file.
