That is pretty much what Windows 10 does. Okay, maybe not quickly switch to the new version as we all know that it can take 10 - 20 minutes sometimes, but here is the thing. By default it reboots and install the updates when I sleep so I don't notice this. It always puzzles me when I hear that Windows suddenly starts to install updated while you are doing something, because that is not the default. The default is to install and reboot outside of your normal working hours. Best guess is that many people turn off their computer when they don't use it. In that case it is only possible to install the updates while you use that machine.

If the update is fully downloaded, you have the option to "install & shutdown"
