How to Modify the Undo Limit in Microsoft Office Word, Excel, or PowerPoint?

Working on Microsoft Office allows you to undo, redo, or repeat several options in MS Office Word, PowerPoint, or Excel. It means you can undo changes, even after saving, and then keep them, as long as you are within the undo limits. By default, MS Office reserves the last 100 undo-able actions, which allows you to undo the previous 100 actions in Word, PowerPoint, or Excel.

However, if you want to increase or decrease the number of these undo-able actions, you can always do that by adding an entry in the Windows Registry. But, in case you are using a slow PC, increasing the number of rebounds over 100 is not recommended since doing so makes MS Office acquire more of your Random Access Memory (RAM) to save the undo history. It may affect your computer’s overall performance and applications like MS Word, Excel, or PowerPoint.

In the same way, if you undo history to zero, no memory is allocated to the process, and thus, your computer runs smoothly. Now, if you still want to change the undo limit in Microsoft Office applications, this risewindows article will help you.
