Re: I'm free!
"So... does that mean that windows is locked to my hardware profile?"
Basically they are saying its the same licence as W7 OEM - which was basically only allowing re-installation during the manufacturer's hardware warranty period. Presumably the OEM builders had an arrangement to do that. In my home experience you can't move, or reinstall, on a new motherboard. Even the W7 Retail seemed to have cloning protection that limited any hardware changes, including a new disk, to one every three months.
If they are treating their free upgrade as an OEM - then that could be debated as fair enough. If that's the only option for W10 then they are cutting out anyone who does their own hardware upgrades.
