I have had my wife running Linux for about 20 years now. At this point running Ubuntu-mate with LibreOffice and Chromium(de-googled) or firefox VLC and Audacity she has most everything she wants or needs on her computer.
If there is anything which NEEDS windows(for me old solidworks) I run a disposable net-blocked cloned instance of a master copy(a fresh from DVD win7 virtual install and then clean solidworks and virtualbox add-ons for win7 reference master never any net access) running in Virtualbox.
