Windows 10: Activate Windows after a hardware change.

Recently installed a new CPU into my computer and now I have this Activate Windows watermark on my screen. The support page said to troubleshoot the key in settings, but all that did was keep giving me errors. I'd rather not resort to having to break my computer, and definitely don't want to buy a new key. Tried contacting support and have been waiting for about a week now. I have Windows 11 so if anyone knows what to do to fix it I would greatly appreciate it.

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.

Activating Windows 11 after a hardware change

Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.

Here is a step-by-step guide to help you reactivate your Windows 11:

1. Check Activation Status:
   
   • Open Settings.
     
   • Go to System > Activation.
     
   • Ensure that your Windows is listed as activated with a digital license linked to your Microsoft account.
     
2. Link Microsoft Account:
   
   • If your Microsoft account is not linked, you need to link it first.
     
   • In Settings, go to Accounts and ensure your Microsoft account is linked to your Windows.
     
3. Run Activation Troubleshooter:
   
   • Go to Settings > System > Activation.
     
   • Click on Troubleshoot.
     
   • The troubleshooter will detect that Windows can't be activated on your device.
     
4. Select Hardware Change Option:
   
   • In the troubleshooter, select I changed hardware on this device recently.
     
5. Sign In to Microsoft Account:
   
   • Enter your Microsoft account credentials.
     
   • From the list of devices linked to your Microsoft account, select the checkbox next to This is the device I’m using right now.
     
   • If you don’t see your device, ensure you are signed in with the correct Microsoft account.
     
6. Activate Windows:
   
   • Click Activate.
     

If you encounter issues where the edition does not match, it is likely because the digital license linked to your account is for Windows 10 Home, and you are now running Windows 11 Home. This mismatch can sometimes cause activation issues.

• Edition Mismatch: If the troubleshooter indicates an edition mismatch, ensure that you are using the same edition of Windows that was originally linked to your digital license. In your case, both should be Home editions, so this should not be an issue.
  
• Correct Microsoft Account: Double-check that you are using the same Microsoft account that was linked to your digital license.
  

Please do let me know if the method I suggested works for you or if you need further assistance.
