Windows 10: Hardware change resulted in problems with Windows activation

I cannot activate Windows on part of my PC. It started in the following way:

I use an old PC where Windows 7 was installed, then I upgraded to Windows 8, then I upgraded part of the PC to Windows 10 and reinstalled the system. After that I activated Windows using settings panel, but received error "0xC004F213".

I tried troubleshooter and clicked on "hardware changed" option, where I chose the old pc and tapped on "Activate". Now I receive only "Cant activate system Windows: We cant reactivate system Windows on this device. Try again later".

I don’t have Windows 7 key anymore, it was long time ago. Is there a way to retrieve the system?

Activation problems after hardware changes and reinstallations.

Hi Meli,

Thank you for posting the query on Microsoft Community.

I do appreciate your efforts and time.

Was Windows 10 activated before re-installing it?

Along with the suggestions provided by Greg, you can also refer the steps below.



The only hardware changes that can negatively impact activation status once you upgrade to free version are the changes to the:

• CPU
• TPM
• Motherboard replacement

The following changes are examples of hardware changes that will NOT impact the activation status:

• HDD/SSD
• Video card
• Adding extra memory

If you replace the CPU, TPM, or Motherboard you may have to re-activate but this will not require a purchase of Windows 10.

windows activation—hardware changed siginficantly

From time to time on my thoroughbred PC, I get a Windows activation message that says my hardware changed siginificantly and I have to re-activate Windows. My hardware hasn't changed any more than a network card (went from a wireless g card to onboard lan to a wired network card), and the install is legit. Why is it doing this, and how can I stop it?

 

Unable to activate Windows after hardware change

Hi,

Thank you for writing to Microsoft Community Forums.

Usually the error code 0xC004F213 comes when there is a hardware change done on the computer (like Motherboard or Hard drive). The Windows license is associated with the device hardware. If there is any significant hardware changes, such as replacing
motherboard or hard drive, Windows won’t be able to recognize the license.

I suggest you to try the troubleshooting steps from the article
Reactivating Windows 10 after a hardware change and see if Windows gets activated.

If you are using an OEM computer that came with Windows 7, and the motherboard has not been changed, then you can follow the steps to retrieve the product key that came with your OEM computer. To retrieve the product key follow the steps mentioned
below:

1. Type Command prompt in the search bar, that is on the taskbar.
   
2. Right click on Command prompt icon and select Run as administrator.
   
3. Type the command and press on Enter: wmic path SoftwareLicensingService get OA3xOriginalProductKey
   
4. You will find the product key.
   

Hope it helps.

Please reply with the status of the issue, we will be glad to help you further.
