How to modify the number of Undo levels in Excel

Although Microsoft Excel allows users to undo action 6 times, you can increase or decrease this number with the help of this guide. It is possible to modify the number of Undo levels in Excel using the Registry Editor. Here is what you need to do in the Windows Registry to get things done.

Like some other programs, which allow users to edit files, you can undo changes according to your requirements. Let’s assume that you have made several wrong changes in your spreadsheet. The best way to get rid of them is by using the Undo option. However, the problem starts when you need to undo changes more than six times.

Even if you are using the latest version of Microsoft Excel, you won’t be able to undo changes more than six times. That is because Microsoft Excel allocates RAM for storing only six previous changes. If you increase this number, Microsoft Excel will start using more RAM than the default setting. In other words, if you do not have much RAM, you will have lagging while using Microsoft Excel.

However, at times, you might need to enable more undo levels than the default one. In such situations, you can follow the Registry Editor guide to get the change done. As you are going to make changes in the Registry Editor, it is highly recommended to create a System Restore point.
