Let’s assume that you have made a few unnecessary or incorrect changes in a Word document. There are two ways to rectify the mistake. First, you can change all the wrongdoings manually. Second, you can press Ctrl+Z to undo all the changes. However, if the number of mistakes is more than 20, you won’t be able to get things done. In such situations, you need to increase the number of Undo limits in Word. The problem is that Word doesn’t come with any in-built option for modifying the undo limit. That is why you need to use the Windows Registry to make the change. Although the default number is 20, you can set almost 100 in some cases. However, the higher the number, the more RAM is required for storing the Undo histories. It is highly recommended to backup Registry files and create a System Restore point before heading to the steps.
