EULA
At what point does Windows 10 present you with a EULA and give you the choice to decline? Windows 10 forces itself on people with choices like 'install now' or 'install later'. They cannot stand behind an un-inforcable EULA and say you gave them permission. Can I use that defence if I rob someone? I asked them for their wallet and 'they' gave it to me. (I was holding a gun at the time). It is illegal to frig with someone's computer without their consent.
