I am trying to upgrade my Win7 system to Windows 10 (because I am, apparently, masochistic). It's not working, locking up at about 30 to 35%, requiring me to reset, which then backs out the upgrade.
The whole process takes about three to four hours. A large part of this is having to download 3.5GB of upgrade every time, because Microsoft's tool doesn't cache the install files.
The tool has an option to create a bootable USB stick, which I can use to do an install. This should be way faster.
However, Microsoft seem really firm that if I want to get my free upgrade, I need to pick to 'Upgrade this PC' option from the upgrade tool. This seems peculiar. Can anyone confirm (i.e. who actually knows from first hand knowledge) whether upgrading from a USB stick actually works?
