Are you Zorin lite user?

Me, using 16lite Cinnamon.

I started using Cinnamon because the original Zorin xfce got bricked somehow. I dont know how to get it back and running like it should, tried to find a solution myself without reinstalling. I never had to install Cinnamon, it was just there. I could choose it because it was already in the list of DE's.
I know there must be a cli command to get the original zorin xfce back, but I could not find it, anyone? Please?
