I’m guessing he has a newer computer with a solid state drive for the operating system?
Those drives are pretty small, usually just enough to hold one operating system, documents, and temporary files. If you try to download the upgrade to that drive there won’t be enough room, because you haven’t uninstalled the old OS yet.
I would try downloading the upgrade to another drive (not the C: drive, that is usually the smaller solid state drive). You can install the new OS to the C: drive, just don’t save the installation files there.
Simply go into windows update, click on update history on left, then click on installed updates up top on right, down a little bit- look for KB3o3558 and right click uninstall- you’ll have to restart machine- When you see the update again in future list- (it will reinsert itself i nthe update list when you go back into updates- it’s very sneaky- keep an eye out for it by doing manual updates, and individual updates, don’t just do updates automatically-) right click it and select ‘hide’ again
Also uninstall the following because they are doing windows spying on you too
