I still use Windows 7 on my desktop pc as it just works.
I have Windows 10 on a few laptops but hardly use them.
Windows 10 is adware and spyware and cannot be easily configured the way I want things to look. I like the Start menu of 10 but little else. It is earlier versions of Windows that someone picked up and dropped then tried to rearrange back together again. Confusing interface and again you are spied on.
