Compare Presentations Manually in PowerPoint 2010 for Windows

Since PowerPoint 2007, Microsoft has removed the feature that let you compare two presentations. This feature was useful if you had send your presentation to a colleague and he or she made changes you were not aware of. You can however place both presentations side by side and compare individual slides. This is not too great a workaround, but it does allow you to compare the slides.

However, doing so will get you to another roadblock—viewing more than one PowerPoint presentation at the same time is little difficult because you need to keep switching between windows. Fortunately, PowerPoint does allow you to open more than one PowerPoint presentation side by side.

Follow these steps to manually compare two presentations in PowerPoint 2010 for Windows:

1. Ensure that only the two presentations you want to use for comparison are open. Close any other open presentations.
2. Access the View tab of the Ribbon. In the Window group, click the Arrange All button, as shown highlighted in red within Figure 1, below.
3.

3. Doing so will arrange both presentations in different windows side by side, as shown in Figure 2, below.

4. If you find some slides are missing in one of the presentations, you can copy slides between two presentations. To do so, you can change to Slide Sorter view, as shown in Figure 3, below.

5. Next, drag and drop any slides, as needed, from one presentation to the other to copy slides.
6. Save your presentation often.
