Windows 10: Cannot activate Windows 10 RETAIL copy after hardware change

Hello,


I have recently changed most of my hardware (motherboard and CPU included), and I can't activate my Windows 10 Retail license now. I have already tried all the steps indicated in the support section, when I run the Windows Update Troubleshooter I get a message informing that the problems were found and fixed. In spite of this, I still get error code 0xC004C003 in the Activation section of the settings menu.


Thanks in advance

:)

 

Windows 10 Hardware change

No. That only applies to an OEM key. IF you had a retail key that you upgraded, you are more than welcome to transfer this key to another device, just as you would have been able to before the upgrade. The default for retail keys is three activations before you need to call in and get help with activation. Previously, it was required that you install your retail OS first and then upgrade, but the most recent build of Win10 removes that requirement and allows direct installation of Windows10 using your retail Win7/8/8.1 key.

 

Windows 10 Activation after hardware change

• "You upgraded to Windows 10 using the free upgrade offer, but Windows 10 isn't activated after a reinstall. Your copy of Windows 10 should automatically be activated so long as you didn't make any significant hardware changes to your device (such as replacing
  the hard drive or motherboard)."

I just recently upgraded my motherboard, graphics card, and processor. Now my Windows 10 isnt activated anymore, and when i go through the steps to troubleshoot, it says the windows activation just says.



Unable to activate Windows

We can’t reactivate Windows on this device. Try again later.

anyone have an answer to this please...

 

Windows 8 Pro Retail => Windows 10 Pro (Free upgrade) Fails Activation after hardware change

Hi,

I bought 2 retail licenses (one for my desktop and one for my laptop) for Windows 8 several years ago and upgraded to Windows 10 (via the free upgrade). Recently I had to change some hardware (motherboard) and I get the following error code when trying to
activate Windows: 0xC004C003.

I have tried the following, all of which have failed.

1. Troubeshoot -> I recently changed hardware on this device (I can only see my Laptop License and not my desktop)
2. Provided the Installation ID (via phone helpdesk) on two occasions.

First help desk technician suggested I buy a new Windows License and the second suggested I reinstall and use Windows 8. Both suggestions from help desk are ridiculous.

How do I proceed without having to:

1. Pay for a license I should technically already have
2. Downgrade back to Windows 8 (loose time / data)
