Question

Windows 11 not activating after new install of windows on a new hard drive

Isaiah Augustin 20

Hi,
I just got a new SSD and installed a fresh version of windows on it. I am having the hardest time trying to activate it. My old hard drive is still connected, and I am able to boot from that if I wanted to and windows is activated and works fine there. It is activated through my digital license through this account.

When I boot from my new SSD, windows can not activate. The profile is signed in through the same account, and my motherboard did not change. When I assigned this account to the profile, the watermark went away, but it still says it is not activated. On the activation page in settings, I have error 0x0803FA067 and the troubleshooter there does not help. I checked the OS version and it is windows 11 home which should be the same as my license.

Is anyone familiar with any solutions? I work in IT troubleshoot and can't figure out whats wrong.

Hi Isaiah Augustin,

I understand that you performed a clean installation of Windows 11 Home on a new SSD, while the original drive is still activated on the same motherboard and Microsoft account.

Since you are receiving error 0x803FA067, I would like to narrow down one detail first:

On the new SSD installation, is the Activation page showing "Windows 11 Home" and are you signed in with exactly the same Microsoft account that appears on the activated installation on the old drive?

In the meantime, please try these checks:

Open "Settings" > "System" > "Activation" and select "Troubleshoot".
If prompted, choose "I changed hardware on this device recently", sign in with your Microsoft account, and select the device that was previously activated.
Confirm that the edition on both installations is Windows 11 Home. A mismatch between Home and Pro can prevent activation.
On both the old and new installations, run slmgr /dlv from an elevated Command Prompt and let us know whether the license channel shows Retail or OEM. This can help determine how the license is being recognized.

Hi Sin-D,

On the new SSD installation, the activation page does show Windows 11 Home, and its the same for the old installation. I am signed in with the exact same account as the old drive. I did some digging and ran some tests with Chat GPT to identify the issue further:

I bought this PC prebuilt around 2015, so I'm assuming it came with windows already installed. I was using windows fine, then replaced my motherboard and cpu in 2022, and Windows continued activating normally on my existing HDD (old drive). I recently installed the new SSD with a clean install of Windows 11 Home on the same motherboard.

The old installation remains activated with a digital license linked to my Microsoft account, but the new installation does not activate. slmgr /dlv on the old installation reports OEM_DM and Licensed. On the new installation it reports RETAIL with the generic Home key ending in 8HVX7 and 0xC004F213. The Activation Troubleshooter finds no eligible devices, although my Microsoft account shows two entries for this same PC.

ChatGPT believes it is an activation record mismatch, and suggests I ask Microsoft to "verify the digital entitlement associated with your Microsoft account and current hardware hash".

Hi Isaiah Augustin,

Thank you for providing the additional details.

The key detail is that the old installation reports OEM_DM and is activated, while the new installation is using the generic Windows 11 Home key (ending in 8HVX7) and reports 0xC004F213, which typically indicates that Windows cannot find a valid license for the current installation.

Since the motherboard was replaced in 2022, there is a possibility that the current digital entitlement is associated with the activation state of the existing installation rather than being automatically recognized by the fresh installation. The fact that the Activation Troubleshooter does not find an eligible device, despite both installations appearing under your Microsoft account, also suggests an activation record mismatch may be involved.

At this point, I do not believe there is another user-side troubleshooting step likely to resolve this. The activation system appears to be recognizing the old installation but not associating the new installation with the same entitlement.

I recommend contacting Microsoft Activation Support directly:

Visit  Contact Us - Microsoft Support

Select the product or service you're having issue with.

Click  Get Home Support

Type a brief description of your issue in the search box.

Click Get Help  and select  Contact Support  below.

Go to the Products and services tab, and choose the appropriate product.

On the Category tab, choose the appropriate category or an alternative option.

Go to  Confirm.

Look for and select "Chat with a support agent in your web browser" (during business hours) if available. Explain your situation clearly.

They can review the activation records associated with your Microsoft account and determine whether the entitlement can be reassigned to the new installation.

If the licence is from 2015 and was OEM on the original installation and you changed motherboard I would have expected activation to be a problem in 2022.

Changing from HDD to SSD shouldn't affect activation on a valid licence.

In 2015 it would have been Windows 10 (I presume) and has since been upgraded to Windows 11. In 2015 it is quite possible that Windows 10 was part of the free upgrade from Windows 7/8. A licence that was originally Windows 7/8 can no longer be used to activate Windows 11. Microsoft changed a loophole in 2023 to block upgrade licences activating Windows 11.

This is why the troubleshooter cannot find a valid licence to transfer to the SSD installation. It sounds like you will need to buy a new Windows 11 licence.
