There is a number of different ubuntus. I have found that they can even be mixed. My wife uses windows 10. I used to do a lot of coding and used windows but linux is better for that as the software can be compiled for both OS's.

My main problem is that I don't mess with my wife's machine unless its blowed up. I built it so I can fix it and its the hardware. I have, pretty much, lost my knowledge about windows as I am now used to something different. When she has a problem I usually just goto a good forum and ask the question. For Windows I use cnet (used to own stock in that one). I usually get answers in 1 day off that one. My main problem with getting answers on the net is that some of the answers are years old. I no longer do that and have found getting current answers is MUCH better!
