I do not want to be rude but when you write it makes me wonder why
you still have Windows and if you ever try to keep up with it,. Reboot
twice is unheard of except from you it seems.


Updates in Windows are downloaded in the background, the dialogue tells
you to minimise and get on with your work. It never nags me although it
does remind me once in a while if my computer is never shut down because
updates are loaded on bootup. Ubuntu requires the update manager to run
or the command line. Neither give way to other work. Their is not
appreciable difference IMHO.

As you say at the end if you used it you would keep up and know more it
seems.


You can shut off updates in both systems but I would not advise that idea.
