Increase or Decrease the Maximum Number of Undos in PowerPoint

PowerPoint allows you to undo multiple actions while editing your presentations. By default, PowerPoint lets you undo up to 20 previous actions. However, you can customize this setting to increase or decrease the maximum number of undos.

Why Adjust the Maximum Undos?

Having more undos enables you to revert back further while editing your slides. This gives you more flexibility to experiment without worrying about making permanent changes.

On the other hand, allowing fewer undos improves PowerPoint’s performance. If you don’t use the undo feature much, limiting the number of undos can make editing smoother.

How to Change the Maximum Number of Undos

Follow these simple steps to adjust the maximum number of undos in PowerPoint:

  1. Open any PowerPoint presentation.
  2. Click the File tab.
  3. Select Options from the left sidebar. PowerPoint Options
  4. Under Advanced, scroll down and find the Undo levels setting. Undo Levels Setting
  5. Adjust the number using the up/down arrows or by typing a value directly in the box.
    • The minimum is 5 undos.
    • The maximum is 300 undos.
  6. Click OK to save the new setting.

The updated maximum undos will apply to all your PowerPoint presentations going forward.


  • Set a higher maximum if you want more flexibility to experiment with designs and effects. 100-200 undos gives plenty of room.
  • Limit the undos to 20-50 if you need better performance and don’t use the feature much.
  • The new setting takes effect immediately without having to close and reopen PowerPoint.
  • Each undo takes up a small amount of memory, so don’t set an extremely high number unless needed.

Keyboard Shortcuts

Instead of digging through options, use these handy keyboard shortcuts to undo and redo actions:

  • Ctrl + Z: Undo
  • Ctrl + Y: Redo

So if you accidentally delete something, hit Ctrl + Z right away to undo it!

Adjusting the maximum undos in PowerPoint is simple yet useful. Increase it if you want more editing flexibility or decrease it to improve performance. Just modify the “Undo levels” setting under the PowerPoint Options.
