Another question...
Can I download everything required for an upgrade from Win7 to Win10 and do it all offline? I have a very slow internet connection (1.1 MBps) and it would be more convenient to download it while I'm doing something else rather than waiting for the upgrade tool to spend ages downloading stuff while my PC is unusable. The info for offline installation only refers to clean installs, not upgrades from 7.
Yes, that's how I upgraded one of my machines. Only needs internet to activate.
