Unable to activate Windows 11 Pro digital license after device change

Dejan Strbad 0

Hello,

I had a digital license for Windows 11 Pro on my previous device, linked to my Microsoft account (PII Removed ******@gmail.com). That device has been removed from my account.

I upgraded my new laptop from Windows 11 Home to Pro using the generic key .

Activation fails with error code , and the device does not appear under account.microsoft.com/devices.

I am signed in with the same Microsoft account on the new laptop, but the license did not transfer automatically.

Microsoft support does not offer chat or callback options, and activation via PowerShell also fails.

Could someone please help me transfer and activate the digital license on this new device?

Thank you in advance.

If you had the original licence upgraded via a free upgrade those licences are not allowed to be used for Windows 11 anymore. You were able to use it previously when changing devices but that loophole has been closed.

I know you have removed the previous device from your devices list which is why the activation troubleshooter wouldn't work for you but that won't change the outcome.

As I said previously this thread has been escalated already.

Hi @Dejan Strbad,

Welcome to Microsoft Q&A forum.

I understand you’re trying to activate Windows 11 Pro on your new laptop and you’re seeing error 0xC004C003. This error typically means Windows activation has rejected the current key/license attempt (for example, the key is not valid for this edition/device, is blocked, or the Pro entitlement isn’t being detected).

Because digital licenses are tied to a device’s hardware, moving to a new laptop may require reactivation. If your Pro license is a Retail license and it was linked to your Microsoft account, you can usually reactivate using the built-in Activation Troubleshooter after signing in with the same Microsoft account. Microsoft also recommends ensuring the digital license is linked to your Microsoft account before/when reactivating after a hardware change.

If the troubleshooter cannot locate the Pro entitlement (for example, the previous device doesn’t appear in the selection list or activation still fails), then contacting Microsoft Support (to reach a live support agent, visit https://support.microsoft.com/contactus, sign in, select Windows, then follow the prompts to start chat or request a callback (if available in your region) is the right next step, and they may request proof of purchase (such as Microsoft Order History / receipt) to verify eligibility.

What to provide Support to speed things up:

Error code: 0xC004C003 The Microsoft account used for the Pro purchase/license Whether the license was Retail (purchased separately) or OEM (preinstalled) Proof of purchase / order details (if applicable) Current Windows edition shown in Settings > System > Activation

Once the correct entitlement is recognized (or corrected by Support if needed), Windows should activate normally.

Thank you for your patience and your understanding. If you have any questions, please feel free to reach out.

Thanks, Ian.

Just to clarify: I previously changed my entire hardware (motherboard, CPU, storage) multiple times on my old device, performed clean installations, and Windows 11 Pro always activated automatically through my Microsoft account.

This means the license was transferable and not OEM.

The only difference this time is that I removed the old device from my Microsoft account before activating the new one.

Since the Activation Troubleshooter cannot find the old device anymore, the digital license is no longer linked to my account.

Could you please escalate this to a Support Engineer who can manually reassign the entitlement to my Microsoft account?

This is the only step that can resolve the issue.

Does the purchase of the Pro licence still show on your purchase history on the account you are using. (is it shown as a Windows 10/11 Pro licence?) With the licence record visible in your purchase history Microsoft Support are the only ones that can help.

If you remove the licence from the old device prior to the transfer this is going to remove the opportunity to use the activation troubleshooter.

I did escalate the thread but it has since been removed.

Thanks, Ian.

Just to clarify the situation, because this is not a standard Retail/OEM activation case:

• I did not purchase a Windows 11 Pro license.

• Microsoft granted me a free upgrade path years ago, and the Pro digital license was automatically assigned to my previous device.

• Despite that, I was able to change all hardware components multiple times on that device (motherboard, CPU, storage, clean installs), and Windows 11 Pro always activated automatically through my Microsoft account.

• This confirms the license was transferable and not OEM‑bound.

• The only difference this time is that I removed the old device from my Microsoft account before activating the new laptop.

• Because of that, the Activation Troubleshooter cannot find the old device anymore, and the digital license is no longer linked to my account.

• The Get Help app does not offer chat or callback options in my region, so I cannot reach a live support agent.

Given this, could you please escalate this to a Support Engineer who can manually reassign the entitlement to my Microsoft account?

This is the only step that can resolve the issue.

Thank you.

Hi @Dejan Strbad,

Thank you for the additional information. I understand that your Pro license was an entitlement from a previous free upgrade path and that you've successfully moved it across hardware changes before.

To clarify, this is a user-to-user community forum. As a Moderator, I do not have access to Microsoft’s internal activation servers or account databases. I cannot personally escalate this to a Support Engineer, as no one on this platform has the administrative authority to manually reassign entitlements.

Even though your license is transferable, the Activation Troubleshooter requires a "source" device to be linked to your account to initiate the transfer. Because the old hardware was removed before the new laptop was activated, the automated link was broken, leaving the license "orphaned" in the backend.

Since your regional "Get Help" app is restricted, you need to bypass the automated bots by using higher-priority keywords on the Microsoft Contact Us web portal:

Sign in and type "Billing" or "Account Security".

Select Contact Support > Windows > Technical Support.

This should unlock the "Chat with a support agent" option.

Only an official Microsoft agent with account-level permissions can resolve this.

Thank you for your cooperation and understanding.
