Frequently asked questions about legality and reliability
Is it legal to buy a cheaper Office or Windows license?
Yes. In the European Union, the resale of some software licenses may be allowed under conditions. The Court of Justice of the European Union set this principle in the UsedSoft v. Oracle ruling (2012). We distribute Retail and ESD licenses that can be activated 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 a PDF invoice. The transaction is transparent, traceable and covered by our commitments.
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 activation help: if there is an activation problem, we replace or refund.
How can you tell a reliable website?
Seven concrete signals: (1) an identified company with SIRET, (2) a PDF invoice, (3) Retail keys that activate online with Microsoft, (4) reachable support, (5) verified customer reviews, (6) 30-day activation help, (7) secure card payment. AllKeyMasters brings these points together.
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, activation help 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, a PDF invoice issued by a company registered in France is provided with new orders.
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 activation help: key replacement or refund. Contact support and we will review your case.
