The most important thing you can do is to leave your PC alone whilst it applies the 700mb update. I would suggest overnight as hours later it is still up to something in housekeeping mode. Looks like a huge update in a small compressed packet but you have to allow plenty of time for the PC to work on it. SSD and a faster PC with lots of cores are quicker but even so I suggest overnight. One of my virtual machines decided it needed a further update and is installing on shut-down.
