Re: Not a problem here.
One of my laptops has this behaviour - looks like it is an issue if you have a dedicated GPU as well as an iGPU. There is a solution - run the install but when it begins "installing" after downloading the update turn off the internet connection. Elegant it is not and I for one would have delayed the install had I known (foolishly updated the laptop after my desktop update with no problems (I don't use cortana or chrome on my desktop).
