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.
When you are satisfied with the changes you have accepted, click End Review. Only the changes you have accepted will appear in your presentation.
In the Reviewing pane, the Details tab lists every change that has been made to that slide, as well as all the comments. Click a change to see its location on the slide.
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.
Compare also allows you to view comments from the person who reviewed your presentation. To read a comment, click the comment thumbnail.
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, simply leave the check box unchecked.
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.
Click Next to view the next change in the presentation. You can also click Previous to view the previous one.
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 This Slide or Accept All Changes to the Presentation.
To compare your presentation with another file, click Compare, then browse for and open the desired file.
