We do get update notifications in many linux distros as well. I guess the difference is how aggressive the windows updates are. Its like having a gun to the head if at all there give a choice in the first place. The fact that windows is still kicking around with these shitty ux practices says how low the desktop or laptop market must mean to companies these days.
The major difference is Linux can update in the background, with out much effect on working performance. Linux also doesn't force you to update, or block shutdown/boot events to perform an update. Its simply a much better experience.
