These are effectively locked to the a limited number of hardware changes per time period before they force you to talk to someone at microsoft to transfer the license to new hardware.
The alternative is to buy a Windows license from Microsoft direct, but the only direct option they offer to consumers anymore is an account-bound license, so you'll need to set up with a Microsoft account for initial activation on new hardware (of course, if recent Insiders builds are any indication, soon everyone will).
