To remove unused ribbon tabs

[wjkim]

I uninstalled the Fuzor program. 
But, it still remains on the ribbon tab in AutoCAD 2020.
I can't find the item in the CUI's Ribbon.
How can I remove it?

Did you restart your computer afterwards? It is often required. Do it now.

Then try CUIUNLOAD command: look up usage in HELP.

The program was deleted a week ago and the computer was rebooted several times.
When I unload Featured Apps from CUIUNLOAD, Fuzor also disappears.

Thank you.
