    Product Key


    Keys are not required for the upgrade process. Windows 10 has a built-in generic key which it uses to install - it acquires the underlying Win7/Win8 activation during the upgrade process and assigns your device ID as a valid Windows 10 activated device. Subsequent installs will thus activate using your device ID. You will not require a key - should you be prompted, select "skip". Activation is automatic thereafter.

    My Product Key


    I have hit another roadblock in my marathon two-day attempt to restore the laptop that Windows 10 destroyed. I do not have the product key for the device, so cannot even revert to Windows 8.1. The product key is not shown in the Amazon purchase listing for the device, and I long ago lost the paperwork. Is there any way I can look it up (keeping in mind of course that the device itself is utterly unusable in its current state)?

    Key Product Devices

    Using the current device's product key on my another device.


    On old PC:
    Uninstall retail product key:


    1. Disable secure boot(if turned on in BIOS)
    2. Boot into Windows
    3. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
    4. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.
    5. Restart
    6. Wait a little while and then use the retail key on the new machine.
    7. Set up secure boot(recommended)
    Your old machine should go back to home, or you might need to do a clean install, I'm not sure there.
