To be fair, Windows 10 is great when it comes pre-installed on a new laptop - it just doesn't work when it's put retrospectively onto a computer; apparently it's because the old operating system isn't deleted, rather stored somewhere so you have two systems fighting each other and slowly breaking the computer

Turned off automatic updates on my laptop and applying any manually. Windows 10 then does not get downloaded and stops the auto install. Windows 7 is supported by Microsoft until 2020. Backout within 30 days from 10 to 7 (or 8.1) is not a clean restore and leaves corruption in the registry, that prevents such tasks eg Backup not working.
