Computers don’t always work the way they’re supposed to. Nothing is more frustrating than when a program locks up and stops responding, or worse, completely crashes—especially if you lose progress on an important presentation that you’re working on.
Fortunately, PowerPoint will try to automatically save backup copies of your presentations. If PowerPoint 2019 encounters a problem and stops responding, you can restart PowerPoint or your computer and try to recover your lost presentations.
You can further protect your work by using the AutoRecover feature to periodically save a temporary copy of the presentation you're working on. To recover work after a software failure, you must have turned on the AutoRecover feature before the problem occurred. You can set the AutoRecover save interval to occur more frequently than its default setting of every 10 minutes.
Click the File tab.
Make sure the Save AutoRecover information check box is checked.
Adjust the time interval.
You can’t specify the interval if the check box is not selected.
Even with PowerPoint’s recovery features, the best way to ensure that you don’t lose much progress is to save your work regularly.
