Using the PowerPoint presentation review feature can help you prepare and get feedback from others on your slides before you present.
If you are collaborating on a presentation or asking someone to review it, you might want to use the Compare feature. This feature combines two versions of the same presentation, allowing you to see all of the differences between the two and decide which changes to include in the final version of your presentation.
Compare also allows you to view comments from the person who reviewed your presentation. To read a comment, click the comment thumbnail.
In the Reviewing pane, the Details tab lists every change that has been made to that slide, as well as all of the comments. Click a change to see its location on the slide.
In the Reviewing pane, the Slides tab lets you view the revised version of each slide. Click the slide to see a larger preview of what the revised slide will look like in your presentation, or click the check box to accept all revisions to the slide.
In addition to reviewing changes individually, you can accept multiple changes at once. Click the Accept drop-down arrow and select either Accept All Changes to the Current Slide or Accept All Changes to the Presentation.
Click Next to view the next change in the presentation. You can also click Previous to view the previous one.
To compare your presentation with another file, click Compare, then browse for and open the desired file.
When you are satisfied with the changes you have accepted, click End Review. Only the changes you have accepted will show up in your presentation.
Click the revisions icon anywhere it appears on a slide to see the changes that have been made in that spot. Check the check box next to each revision you want to accept. To reject a change, leave the check box unchecked.
Some changes, like inserted or deleted slides, will show up on the Slides tab on the left. Click the revisions icon to see the change, and click the check box if you want to accept it.
