    Whoops. I have mixed up my Windows licenses.

    I have an OEM Windows 7 license, upgraded to Windows 10 for free. I have two full Windows 10 Retail licenses, one a physical copy and the second a digital download.

    I have one MacBook, one iMac and one PC. For various reasons I'm always removing and re-installing my Boot Camp partitions. I have three license key numbers written down but now I can't remember which I installed on what computer (Boot Camp is not currently installed so I can't retrieve the key directly from Windows even if that is possible).

    Does anybody know a good way to work out which key belongs to what device? This time I'll make a record of it.

    Or if you just want to find Windows key information, you can always "Run command prompt in Administrator", and enter following command to retrieve this, although it only contains five characters of your full key.
    slmgr.vbs /dli
    slmgr.vbs /dlv
