Changing Office 2000's Excel Undo History

By default, Excel has only approximately 16 undo's you can perform.

To increase that number:

1. Start Regedit
2. Go to HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 9.0 \ Excel \ Options
3. Add a dword called UndoHistory
4. Give it the value you want for the amount you want.
