Duplicate Profile

Hi running windows 10 on Kodi 16.1.
I have set up Kodi as I like it atm, my trouble is I don’t want it fiddled with etc by my children etc.
I have nothing on Kodi that I am worried about my family seeing, but I would like a separate profile for them, I want this profile to be exactly the same but just that they cant fiddle haha.
Obviously I will put a password on my profile so they cant get into it.

I did try to create separate profile for them but although I selected keep default I’m still getting a profile like a fresh install.
Any help would be great thank you
