Frequently asked questions

How fast will I get my product key?

Instantly. Once your payment is confirmed, your key shows on the order page and is emailed to you, usually within a minute. If a key is ever delayed, we'll send it within 2 hours.

Are these genuine Microsoft licenses?

Yes. Every key is a genuine retail license bought from authorized distribution and activates with Microsoft's own servers. If a key won't activate, we replace it or refund you.

Is this a one-time payment?

Yes. Every Windows and Office 2024 key is a one-time purchase that you keep for good, with nothing to renew.

Where do I download Windows or Office?

Directly from Microsoft. Windows comes from microsoft.com/software-download (Media Creation Tool or ISO), and Office from microsoft.com/setup after you redeem the key. We link both on your order page.

Can I move the license to a new PC?

Retail Windows licenses can be moved to a new PC once you deactivate the old one. Office 2024 is tied to your Microsoft account and can be reinstalled on a new device.

What if my key doesn't work?

Contact [email protected] with your order number and a screenshot of the error. We'll replace the key or give you a full refund, and our activation guarantee lasts 30 days.

Is Windows 10 still worth buying?

Only for a PC that can't run Windows 11. Microsoft ended free Windows 10 support on 14 October 2025, so security updates need paid Extended Security Updates. A Windows 10 key also activates the matching Windows 11 edition on supported hardware.

Which payment methods do you accept?

All major credit and debit cards, Apple Pay and Google Pay through our secure checkout. We never see or store your card details.
