PowerPoint 2007: Add More Levels of Undo

You can go back farther than the default 20 undos in Microsoft Office PowerPoint to undo up to 150 actions.
  1. With PowerPoint open, click the Office button, and then click PowerPoint Options.
  2. On the Advanced tab, change the Maximum number of undos from the default 20 to any number from 3 to 150.


  1. I had around 35 slides on powerpoint 2007, my book hit the delete button and deleted it all. I tried changing the number of undos to 40, but it won't let me retrieve more than 20 of my slides as I changed after all by slides had been deleted, is there anyway that I can retrieve them?


  2. Shirin, unfortunately, even though you may be able to increase the number of undo levels, you will still be limited to your computer's memory. My guess is that the 20 you recovered was all that your computer memory could handle. You only option would be to close and not save changes. Good luck!
