I know they will block any product key if it is used too many times within a certain timeframe. What is happening is:Īnd then the other question is if the product key isn't associated with the digital license/hwid, how is it that "uninstalling" a product key lets you reuse it on a different machine(for retail keys)?Whether or not Microsoft blocks a product key is up to them. Seems weird how it was able to activate a VM.Īnd then the other question is if the product key isn't associated with the digital license/hwid, how is it that "uninstalling" a product key lets you reuse it on a different machine(for retail keys)? Now the question is, does Microsoft change the product key to be invalid? Remember I have an OEM product key which shouldn't be able to activate other installations. It's valid, Microsoft adds an entry for hardware id ABC with permanent digital license Microsoft checks with it's servers that it's validģ. Your host machine already has its own digital licence and it is that which activates it.So let me get this straight. The fact that the key has been used is recorded elsewhere, but that only means you shouldn't be able to use that key to activate another machine. The actual key used to get that digital licence is not recorded or linked to the digital licence. Once a key has been used to obtain a digital licence the activation severs only keep the hardware ID of the machine.
