Hide/Unhide Slides in PowerPoint 2010 for Windows

You have a secret slide with useful information that you do not want to delete. But you don’t want to show it to your audience inadvertently! What do you do? The solution is easy: you just hide the slide. Hidden slides don’t show up in Slide Show view, but they are still available to edit and to possibly unhide when you are ready to show that slide to the world.

Follow these steps to hide and unhide your slides in PowerPoint 2010:

1. Open your presentation that contains slides you want to hide. To make the hiding process easier, view the slides in Slide Sorter view, as shown in Figure 1, below.

2. Next, you need to select the slides that you want to hide. To select a single slide, just click on it. To select multiple, non-contiguous slides, select the first one, and then press the Ctrl key as you click on other slides. To select contiguous slides, select your first slide, and then press the Shift key and click on the last slide you want to select—you will end up selecting all slides in between.
3. Whatever selection options you choose, you will end up with a selection of one or more slides, as can be seen in Figure 2, below.

3. Now carefully right-click on any selected slide to bring up a contextual menu, as shown in Figure 3, below. Choose the Hide Slide option, highlighted in red within Figure 3.
