How do we get our ESU Keys for Windows 10 Pro

Hi Terry Schneider,

The good news is that your ESU purchase is valid, but the keys are not always surfaced directly in the Admin Center interface. Instead, ESU keys are distributed through the Volume Licensing Service Center (VLSC) or, for certain nonprofit customers, through the Microsoft 365 Admin Center’s licensing portal once provisioning is complete.

Since you’re seeing the product listed but encountering the error message when clicking through, this usually means the provisioning process hasn’t fully completed on the backend. I recommend signing into the VLSC with the same credentials tied to your nonprofit license agreement. Once there, navigate to the “Downloads and Keys” section—you should see the ESU product listed, and the activation keys will be available there. If you don’t see them, please open a support request through the Admin Center under Billing > Licenses, and specify that you need ESU keys for Windows 10 Pro. Microsoft Support can then manually provision the keys to your account.

For nonprofit organizations like yours, the entitlement is the same as for commercial customers, but sometimes the portal integration takes longer to sync. Rest assured, once the keys are provisioned, you’ll be able to activate ESU on each of your 24 devices without issue.

I hope the response provided some helpful insight. If it clarified the issue for you, please consider marking it as Accept Answer so others with the same issue can find the solution.

Use the Volume Licensing area of the Microsoft 365 admin center and the ESU-specific product key view. The ESU keys are exposed as Multiple Activation Keys (MAKs) under the volume licensing contract that the ESU order was placed on.

Follow these steps to get the Windows 10 ESU keys:

1. In the Microsoft 365 admin center, go to Billing > Your products.
2. Select the Volume licensing tab.
3. In the Contracts section, select View contracts.
4. On the Contracts page, locate the License ID under which the Windows 10 ESU licenses were purchased.
5. For that License ID, select the three dots (More actions) and then select View product keys.
6. On the Product keys details page, look for the Windows 10 ESU entry; the ESU Multiple Activation Key (MAK) for that contract will be listed there.

Role requirement:

• The account used must have either the Product Key Reader or VL Administrator role in Microsoft Entra ID to see the MAKs. If those roles are missing, assign one of them and then repeat the steps above.

If the View product keys page continues to fail with an error or the ESU MAK does not appear even though the ESU licenses are visible, contact Microsoft Volume Licensing support so they can correct the contract linkage and/or provide the keys directly.

• Use the Contact volume licensing support channel referenced in the ESU and product-keys documentation.

Once the ESU MAK is obtained, it can be installed and activated on each Windows 10 Pro device using slmgr.vbs as described in the ESU enablement documentation.
