Delivery & turnaround

Delivery is typically completed within minutes after the order is processed. In most cases, the key or activation details are sent quickly, and you can proceed with activation right away.

Frequently asked questions

Is this license for one computer only?

Yes. This product is intended for activation on one PC. You should use it on the device specified in your order and keep the activation tied to that installation unless otherwise stated in the service details.

Will this work on both Windows 10 and Windows 11?

The key is for the Professional edition and can be used on Windows 10 Pro or Windows 11 Pro, as long as the installation and hardware are compatible with Microsoft’s activation rules. If you are unsure which version you have, we can help you check before activation.

Do I need to reinstall Windows first?

Not always. If your PC already has a compatible Windows Pro installation, you may be able to activate it without reinstalling. If you are moving from a different edition, such as Home, you may need to upgrade or install the correct edition before the key can be accepted.

How fast will I receive the key?

Delivery is usually very fast, often within minutes. If the order requires extra review or if there is a verification issue, it may take longer. We will keep you informed if any delay comes up.

What should I do if activation fails?

If activation does not complete, check that you entered the key exactly as provided and that your device is running the Professional edition. If the issue continues, send us a screenshot of the error so we can review the case and guide you through the next step.
