> 10 minutes
I guess I have never seen Windows update take 10 minutes. Did you add the restart time into that? Because the restart after an update usually takes half of that alone.
10 minutes is around the login time for new user at my work computers. (That is, after it is fully booted and loaded, just the time for the user to log in.)
But yeah, the Mac updates aren't even remotely as bad as Windows.
