Before presenting your PowerPoint, you might decide to ask someone else to look over it. The two of you might even collaborate on a presentation. If you were revising a hard copy of a report, you might add comments in the margins or compare your rough and final drafts side by side. You can also do these things in PowerPoint using the Comments and Compare features

When you are revising or collaborating on a presentation, you might want to make notes or suggestions without actually changing anything on the slide. Using comments allows you to take note of anything on a slide without altering the slide itself. Comments can be added and read by the original author or any other reviewers.
Added comments show up as small thumbnails rather than full-sized notes. To read a comment, click the thumbnail to open the Comments pane.
To delete multiple comments, click the Delete drop-down arrow and select Delete All Comments and Ink on This Slide or Delete All Comments and Ink in This Presentation.
If you are collaborating on a presentation or asking someone else to review your presentation, you might want to use the Compare feature. The Compare feature combines two versions of the same presentation. This allows you to see the differences between the two and decide which changes to include in the final version of your presentation.
Before you start, you'll need to have one version of the presentation open. When you're ready to compare, you'll select the second version.
Click the buttons in the interactive below to learn how to review comments and changes using the Compare feature.
Some changes, like Inserted or Deleted slides, will show up on the Slides pane. Click the revisions icon to see the change, then click the check box if you want to accept it.
In addition to reviewing changes individually, you can accept multiple changes at once. Click the Accept drop-down arrow, then choose either Accept All Changes to This Slide or Accept All Changes to the Presentation.
To compare your presentation with another version, click the Compare command. Next, locate and select the desired file.
Use the Next command to view the next change in the presentation. You can also click Previous to go back to the previous one.
When you're satisfied with the changes you've reviewed, click End Review. Only the changes you've accepted will be applied to the final presentation.
The Slides tab actually lets you preview the revised slide, so you can see the changes in action (as opposed to the Details tab, which only lists the changes).
The Details tab lists every change that has been made to the current slide, as well as any comments. Click a change to see its location on the slide.
Click the revisions icon anywhere it appears on a slide to see the changes that were made in that spot. To accept a revision, click the check box beside it. To reject a revision, leave the box unchecked.
