Windows 7, 8, 10? I'll take 9, please.
Windows 10 is being patched? That OS is spyware all by itself. They're just worried somebody else may get the information they want to be theirs alone. I'll stay with 7. I'd consider Linux, except somewhere along the way, Linux stopped working on my Linux-rated tower. It seems to run, but the display twitches and jumps around.
Upgrades are not always improvements.
