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

Windows 10 Product Key

Hi Oscar,

Since the laptop has no battery compartment wherein the product key is usually located, we recommend that you follow these steps to find your Windows product key:

• Press Windows + X and select Command Prompt (Admin).
• Enter this command: wmic path SoftwareLicensingService get OA3xOriginalProductKey
  and hit Enter.

Also, if you're looking to reinstall Windows 10 after a hardware replacement, we recommend that you follow the steps provided in this

article.

Let us know if performing these steps resolved the issue.
