Excel 2016 2013 2010 2007 2003
By default, the number of Undo levels in Excel for Microsoft 365 is 100. You can increase or decrease this number if it's necessary.

To change the number of Undo levels, follow these steps:

   1.    Launch Registry Editor.

   2.    In the Registry Editor, navigate to the HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Excel\Options subkey:

   3.    Right-click in the right pane and choose New -> DWORD (32-bit) Value:

New in the Registry Editor Windows 10

Registry Editor creates the new value with a name such as New Value #1 and selects this name for editing.

   4.    Type the name UndoHistory over the default name and press Enter to apply the name.

   5.    Press Enter to display the Edit DWORD (32-bit) Value dialog box:

Edit DWORD (32-bit) Value Windows 10

   6.    In the Value Data text box, enter the number of Undo levels you want-anywhere from 0 to 100, hexadecimal base (256 actions - the biggest number, decimal base).

   7.    Click the OK button to close the Edit DWORD (32-bit) Value dialog box.

   8.    Choose File -> Exit to close Registry Editor.

   9.    Close Excel if it's running, and then restart it to make the changes take effect.
