Licensing & Authenticity

Every key we sell is genuine and activates through Microsoft’s own servers. Here is exactly why our licenses are legitimate, how you can verify authenticity yourself, and the guarantee that protects every purchase.

1. What We Actually Sell

GenuineKeys365 is an independent software reseller. We supply genuine Microsoft product keys — for Windows, Office, Windows Server and related products — that activate directly with Microsoft and receive official updates like any other genuine license. We describe every product honestly, including its edition and license type, so you always know exactly what you are buying before you pay.

We are not Microsoft, and we do not claim to be an official Microsoft store or a Microsoft-endorsed partner. What we offer is genuine licenses at a fair price, sold lawfully — and the transparency to prove it.

2. Why Reselling Genuine Keys Is Legal

Our business is based in Stockholm, Sweden and operates under European Union law. Under the EU principle of “exhaustion of rights”, once a software license has been sold within the European Economic Area with the rightsholder’s consent, that license can be legally resold to another buyer.

This was confirmed by the Court of Justice of the European Union in the landmark ruling UsedSoft GmbH v. Oracle International Corp. (Case C-128/11, 2012), which established that the resale of “used” software licenses is lawful, even for downloaded software delivered without a physical disc. It is the same legal principle that lets you resell a book, a car, or any product you legitimately own.

In short: we deal only in genuine, legitimately-sourced licenses, and EU law expressly permits their resale. That is the entire basis of our business — no counterfeits, no cracks, no “pirated” software.

3. Verify Authenticity Yourself

You never have to take our word for it — a genuine key proves itself through Microsoft. After activating, you can confirm your license is authentic in seconds:

  • Windows: open Settings → System → Activation. A genuine, active license shows “Windows is activated with a digital license” or “with a product key.”
  • Command check: press Win + R, runslmgr /xpr to confirm the license status, or slmgr /dlifor license details.
  • Office: open any Office app → File → Account. A genuine license shows the product as activated under your account.
  • It activates with Microsoft directly — not through us, not through any third-party tool. If it activates on Microsoft’s servers, it is genuine.

4. Genuine — Or Your Money Back

Every order is protected by our 30-day money-back guarantee. If a key does not activate and our support team cannot resolve it or provide a working replacement, you get a full refund. Buy with confidence:

  • Activates or it’s free: a faulty key is replaced at no cost, or fully refunded.
  • 30-day window: a full month to activate and confirm everything works.
  • Free replacements first: most activation issues are fixed in minutes with the right steps or a new key.
  • Refunded to your original payment method: PayPal, card (via PayPal), or USDT.

See the full terms on our Refund Policy page.

5. Instant Delivery & 24/7 Support

Your key is delivered instantly after payment, along with clear step-by-step activation instructions. If you ever get stuck, our support team is available around the clock to walk you through activation or issue a replacement — by email at support@genuinekeys365.com or on WhatsApp.
