Windows 10: How to get Windows 10 product key back.

Recently my old HP laptop's HDD died and I was looking for a replacement. I found one exactly the same which was in use in my desktop but 500GB instead of 250GB. Just to make sure it fit I pugged mine into the laptop to make sure it fit and connected correctly. When I put my SSD back in the desktop it got rid of my windows product key but kept everything else. When I try to reactivate windows it says I can't because my hardware changed. When I tried trouble shooting it said the same thing. It still has windows 10 pro on it just not the key. I've tried updating, restarting, cmd, PowerShell. Not

:)

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

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.
