A self-running presentation advances automatically without requiring mouse clicks. It is ideal for trade shows, kiosks, lobbies, or when you want to send a presentation that plays on its own.
Method 1: Set Automatic Slide Timings
Step 1: Go to the Transitions tab.

Step 2: In the Timing group:
- Uncheck On Mouse Click.

- Check After and enter the number of seconds each slide should display (for example, 00:05.00 for 5 seconds).

Step 3: Click Apply To All if you want the same timing on every slide.(You can also set different timings for individual slides.)

Method 2: Rehearse Timings
Step 1: Go to the Slide Show tab → click Rehearse Timings.

Step 2: The presentation starts in full-screen mode with a recording toolbar.

Step 3: Advance through each slide at the pace you want (click or press the arrow keys).

Step 4: When you finish, PowerPoint asks if you want to save the timings. Click Yes.

The recorded timings are now saved with the presentation.
Method 3: Configure the Slide Show Settings
Step 1: Go to the Slide Show tab click on Set Up Slide Show.

Step 2: Under Show type, choose one of the following:
