The sad irony being that the Windows UI, starting from Win8, became a complete mess, far more different from say Win7 or even XP than any recent Linux desktop manager. Most of my users, some even over 70 with little computer experience, are doing fine on Linux, but I "converted" them before they had to experience that awful mess, so it has been relatively easy: from XP or Win7 to a customized XFCE (its defaults are ugly and unpractical) has been a breeze.
