Some Win10 updates can indeed take an absolute age, particularly if there are a lot and you click 'install now'!
I've found it's best just to let Win10 update itself as it sees fit. If a computer restart is needed, they'll usually schedule that for 0-dark-hundred.
I seem to have more software freezes than before the last set of updates - but again you have to wait for Win10 to do its own auto-defrag...
