Retail can be moved from one PC to another. The one Retail product code can only ever be used on one PC at any one time. Even Education? Do you have a link to where it says it can be installed on two PC's with the same key? I'm running Education on my PC's. I'm using my MSDN keys which are listed as Retail. Well I was, up until I upgraded to the Anniversary Edition. Now they show as activated with a Digital Entitlement?
Removing a device from your Devices list does not deactivate it. I do it all the time. I don't like the lame names Windows auto assigns a PC on a clean install so I change it. Sometimes the old name stays on my devices list anyway and I delete it.
