Frequently asked questions about legality and reliability
Is it legal to buy a cheaper Office or Windows license?
Yes. In the European Union, reselling perpetual software licenses is allowed. The Court of Justice of the EU confirmed this in the UsedSoft v. Oracle ruling (2012): the holder of a perpetual license may resell it, including for downloaded software. We distribute perpetual Retail licenses, activable online with Microsoft.
Do I risk anything as a buyer?
No, for a good-faith purchase. You buy a Retail license from an identified seller (a company registered in France, with a verifiable SIRET), with an invoice in your name. The transaction is transparent, traceable and covered by our guarantees.
Why are your licenses cheaper than the Microsoft Store?
We distribute in ESD digital format: no box, no packaging, no physical logistics, and volume purchasing. It is the same Retail key, activable online with Microsoft, delivered by email within minutes.
Can my key be deactivated later?
That risk exists with dubious keys (misused OEM keys, fragmented volume licenses, already-used keys). Our licenses are valid Retail keys, activable online, covered by a 30-day guarantee: if there is an activation problem, we replace or refund.
How can you tell a reliable website?
Seven concrete signs: (1) an identified company with a SIRET, (2) an invoice in your name, (3) Retail keys activable online with Microsoft, (4) reachable support, (5) verified customer reviews, (6) a refund guarantee, (7) secure payment with buyer protection (PayPal, card). AllKeyMasters meets these seven points.
Are keys under 5 euros scams?
An abnormally low price often hides a misused, already-used or volume key that can be deactivated with no recourse. Saving a few euros is not worth the risk of losing access to your software. We prioritize reliability: Retail license, guarantee and support.
What is the difference between a Retail and an OEM license?
An OEM license is tied to a single computer and is not transferable. A Retail license is transferable to a new PC and legally resellable in the EU. We distribute Retail licenses only.
Will I receive an invoice?
Yes, an invoice in your name, issued by a company registered in France. It is your proof of legal purchase and a key element of a good-faith purchase.
How does activation work?
You receive your key by email a few minutes after payment. You download the software from Microsoft, then activate it with your key online. Our support helps you if needed.
What if my key does not work?
You are covered by our 30-day guarantee: key replacement or refund. PayPal payments also benefit from buyer protection. Contact support, we handle every case.
