Hi, TL.Norman
Welcome to the Microsoft Community. Thank you for sharing your issue. I understand that the redo function in Excel is not working for you, and I sympathize with your situation.
You can try the following steps:
Repair an Office application - Microsoft Support
If that doesn't work you can still try:
- Exit all Office programs
- Make sure there are no files in the following folders:
- Locate to C:\Users\User Name\AppData\Roaming\Microsoft\Excel\XLSTART and press Enter to see if the file exists, if it does, delete it, if it doesn't, close it;
- Locate to C:\Program Files\Microsoft Office\root\Office16\XLSTART or C:\Program Files(x86)\Microsoft Office\root\Office16\XLSTART to see if the file exists, if it does If there is a file, again please delete it, if not, close it;
- Press and hold the Windows key + R at the same time, type regedit and press Enter;
- locate the following keys in turn and rename the excel folder (right click on it and select rename, e.g. rename Excel to Excelold); HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Excel HKEY_CURRENT_USER\Software\Microsoft\Office\Excel
- After performing the above operations, view the problem.
