indows 10/11 Pro purchased from Microsoft Store, no product key delivered (Order #6015739364)

Microsoft Store purchase support must retrieve or reissue the missing product key for this online-store download order; a Microsoft Learn Q&A forum cannot access orders, disclose keys, or attach licenses to accounts.

Contact purchase support

1. Sign in to the Microsoft account used for the purchase.
2. Open Microsoft customer support.
3. Enter Missing Windows product key for completed Microsoft online-store order.
4. Select Contact support, then choose:
   • Windows
   • Billing / purchase or activation
   • Chat or call back, whichever is offered.
5. Provide the agent with:
   • The order number from Order history
   • The confirmation email or invoice
   • The PayPal transaction record
   • A screenshot showing the order as Completed
   • A screenshot showing that neither the email nor Order history contains the key
6. Ask the agent to verify fulfillment of the Windows 10/11 Pro Download order and reissue its 25-character product key. If the first agent treats it as an ordinary activation problem, request escalation to Microsoft Store purchase/order support.

Microsoft directs Windows activation and account/billing issues to its support flow, which can provide chat or other available contact methods.^1^

Why a key is expected for this purchase channel

Microsoft distinguishes these two purchase methods:

• A Windows Pro upgrade bought inside the Microsoft Store app receives a digital license linked to the purchasing Microsoft account, rather than a product key.
• A digital copy bought from the Microsoft online store/website has a product key in the confirmation email, and Microsoft retains its record in Order history.^2^

Your description is of an online-store Windows 10/11 Pro (Download) order, not an in-app Home-to-Pro upgrade. Because the completed order has neither the documented key nor a usable digital entitlement, this is a purchase-fulfillment issue for Store support. Do not buy Windows again while that order is being investigated.

The generic Pro installation key sometimes suggested for Home-to-Pro upgrades is not appropriate here: the VM already runs Windows 11 Pro, and a generic key would not supply the missing paid license.

After support supplies the key

Inside the VM:

1. Open Settings → System → Activation.
2. Select Change product key.
3. Enter the 25-character key provided by Microsoft.
4. Ensure the VM is online and select Activate.

That is Microsoft’s documented path for activating Windows with a product key.^3^

If support instead confirms that the order is a digital license and repairs its association:

1. Sign in to Windows as an administrator with the purchasing Microsoft account.
2. Open Settings → System → Activation.
3. Select Troubleshoot.
4. If offered, select Activate Windows, then Activate.

The troubleshooter is available only while Windows is not activated and requires an administrator account and internet access.^4^

Windows 11 Arm64 can be used to create virtual machines on Apple Silicon Macs, so using an Arm64 VM is not by itself evidence that the purchase is inapplicable.^5^

For privacy, remove the order number, email address, payment details, and unredacted screenshots from any public Q&A post; provide them only through the private Microsoft Support session.
