One of my laptops is on Windows XP but that probably hasn't got the guts inside it to run anything newer - plus I need it for compatibility issues with older software.
My main laptop is windows 7 and that is a very good OS.
My parents' laptop is windows 8.1 and even now I haven't got used to it (when I do use it). Here's hoping windows 10 will be an improvement on window 8.
Hey, just letting you know that gravedigging is not recommended (last comment on this thread was 1 year ago...)
