Don't really care how long an update takes to download as that's done in the background.What pisses me off is that I click "Update & Shut Down" so that me PC updates and then shuts shuts down, not so that when I next turn on it takes 30 minutes to install the updates I've already told to bloody thing to install.
Has to be a way for the PC to reboot if needed, then shut down after all updates actually installed so when I power up next time it's ready to go straight away.
