I face the same specific issue. I started with the French (Canada) layout years ago but now Windows sets the default to Multilingual/CSA because it has been made the official one by the government a number of years ago.

So now everyone that got used the “old” one has to fiddle with keyboard settings every time they use a new Windows session/computer.

And it’s not exactly a breeze to switch, as Windows often keeps the multilingual one and switches back to it when you use a different application. Gotta make sure to delete the multilingual and leave only one layout. It’s a real annoyance.
