Change of licence key- Windows 10

Hi,

The second option that you've posted is actually the best way of moving a hard disk drive to another device. We'd recommend updating the product key once the hard disk drive of machine 1 is already attached to machine 2. To do this, you can perform the following:

• Search and launch Settings using Cortana.
• Click on Update & Security.
• Click on the Activation option.
• Click on Change product key.
• Enter machine 2's product key.
• Follow the on-screen prompts.

We'd recommend performing the steps posted on this
link should the steps posted above don't suffice. The steps are intended for reactivating Windows 10 after a hardware change.

In the event that the recommended steps didn't work for you, we'd recommend contacting our support team. To do this, click on this
