And in the most recent version, it appeared to install more of an update behind the scenes, so there was less waiting if a reboot was required. As to why it’s more visible than Apple updates, I blame the lack of good, settled power management strategies for overnight wake-from-sleep use cases that Apple can specifically include parts and driver tuning for but that Microsoft seems to have a hard time with... oh and they refused to break legacy apps by introducing new APIs that restore app state after a reboot, which Apple introduced back in 10.7 Lion if I recall correctly.
