Question

I have a 0xC004F213 activation fault without changing or doing anything with hardware or software

Brant Huddleston 0

I built my computer in February of 2025 and bought Windows 11 from Microsoft and installed it on my PC. I haven't had any issues with it until this week.

My Activation State says, "not Active" and gives error code 0xC004F2123. I go through the troubleshooting, and it gets me nowhere.

In my about settings under system tab my windows info reflects Windows 11 Home install and the correct date. Can someone help me get to fix this even if I get a new product key and a refund for having to buy a new one?

Thank you.

Your Windows is a bit outdated.

I would suggest that you do a repair install first.

To perform a repair installation of Windows 11 using the Windows Media Creation Tool:

The following steps should be done on a working Windows computer:

Download the Windows Media Creation Tool from Microsoft's official website. https://www.microsoft.com/software-download/windows11 click on the "download now" button under "Create Windows 11 Installation Media"

Run the tool and select "Create installation media for another PC."

Choose "USB flash drive" as the media to use for the installation and select "Next."

Connect a USB flash drive with at least 8 GB of free space to your computer.

Select the USB flash drive you want to use, and then select "Next."

The tool will then download the required files and create the installation media.

=====================================================

Now these steps will be done on your problematic computer:

Go to the USB drive via File Explorer and locate and run the Setup.exe file. Ideally, you should disconnect all USB and Bluetooth devices other than mouse and keyboard. Disable any 3rd party antivirus program. Disconnect the internet.

Once you run the Setup.exe file, choose the Install option, and the choose the option that keeps your files and apps.

Once that's done, if the activation is not working still, Go to Settings > Accounts > Your info

Click on Sign in with local user instead. follow the steps and finish the rest.

(If you don't see the "sign in with a local account instead option, click on "Stop signing into Microsoft apps automatically" first, then relaunch this page. )

Restart the computer (Do Not skip)

Go to Settings > Accounts > Your info

Click on Sign in with Microsoft account instead. follow the steps and finish the rest

Restart the computer (Do Not skip)

Then run the troubleshooter. go to Settings > System > Activation, run the troubleshooter, choose the hardware change option. When it asks you where it is installed on right now, you should choose the old device name. Then click on Activate button. And on the next screen when it asks you where to transfer it to, choose your new device name. See if that does the trick.

If it still doesn't work, you can use the instructions I gave earlier to get a hold of support. They can also manually activate considering you bought from Microsoft.

Hello

Sorry, did you end up getting a new product key during the troubleshooting process?

If so, you definitely want to chat with support to get that returned and refunded, because there's no need to purchase a new one when you already bought one from Msft.

To get a hold of support, open the "Get Help" app on your computer (just search for it in the Start menu). or go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Windows" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.

As for activation, Can you please type cmd in the search on the taskbar and hit enter to launch command prompt, then run the following command:

slmgr /dlv

Then share a screenshot please. Thanks!
