I ordered Windows 11 Pro as an Update for my Windows 11 home as an update. I paid for it, but I connot find the product key now...

If you have purchased a Windows 11 Pro upgrade for your Windows 11 Home edition and cannot find your product key, there are a few steps you can take:

1. Check Your Email: If you purchased the upgrade online, the product key is often sent to your email. Look for an email from Microsoft or the retailer where you purchased the upgrade.
2. Microsoft Store Account: If you bought the upgrade through the Microsoft Store, you can log into your Microsoft account and check your purchase history. The product key may be listed there.
3. Retail Packaging: If you bought a physical copy, the product key is usually found inside the packaging or on a card included with the product.
4. Contact Support: If you still cannot find your product key, consider contacting Microsoft Support for assistance. They may be able to help you retrieve it based on your purchase information.

Make sure to keep your product key in a safe place for future reference.

Hi Helmut Dannemann - Die Dialogschule,

The confusion regarding missing keys and download links is very common with this specific upgrade path because Microsoft handles "Pro Pack" upgrades differently than standalone retail software. When you purchase a Windows 11 Home to Pro upgrade directly through the Microsoft Store interface on the specific machine you intend to upgrade, you generally do not receive a 25-character product key, nor do you receive a traditional installer file. Instead, the transaction creates a Digital License (Digital Entitlement) that attaches directly to your device's hardware ID and your Microsoft Account.

To trigger the upgrade you paid for, you do not need to download an ISO or look for an email code. You need to verify the entitlement within the OS itself. Navigate to Settings > System > Activation. If the purchase processed correctly, the status might ask you to restart to apply features, or direct you to the Microsoft Store. If nothing is happening there, open the Microsoft Store app, make sure you are signed in with the exact account used for the purchase, and go to the "Library" section or search for "Windows 10/11 Pro". Because the backend recognizes the transaction, the button that usually shows a price should now display "Install," "Update," or "Launch."

Clicking that button will download the necessary feature enablement packages—which is not a full operating system re-installation but rather a small configuration update that unlocks the Pro features already present in your system files. The computer will restart, and the Edition listed under Settings > System > About should change to Professional. If the Store still lists a price, verify your transaction status at account.microsoft.com/billing/orders to ensure the payment didn't fail. If the order is "Completed" but the Store doesn't recognize it, sign out of the Store app, run wsreset.exe via the Run dialog (Win+R) to clear the Store cache, sign back in, and try the activation path again.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
