The reason is that I live in France but I’m English.
So windows is installed in French and some other programs, then some other stuff, like Avast for example is installed in English!
I understand both languages perfectly, but sometimes when looking for help with a program or something, it’s in a different language and takes a bit of time working out what I should do! 
lol, even if something is easy, you can trust me to make it a little more complicated!!! hahahha
