Question 1

Is LicenseVault legitimate?

Accepted Answer

Yes. LicenseVault is an independent EU-based reseller of genuine Microsoft retail keys. Every key is first-use or fully transferred and activates against Microsoft's own activation servers. Resale is lawful under the EU exhaustion-of-distribution-rights doctrine established by the Court of Justice of the European Union in case C-128/11 (UsedSoft v Oracle, 2012).

Question 2

How fast is delivery?

Accepted Answer

Typical delivery is under 10 minutes, 24/7. The 90-day average is approximately 8 minutes. Keys are released automatically by email after Stripe captures payment.

Question 3

What is the refund policy?

Accepted Answer

14-day free return on every purchase under EU Directive 2011/83/EU. Selected category landings offer a 30-day money-back guarantee. If a key ever fails to activate, LicenseVault replaces it free of charge for the lifetime of the product.

Question 4

Are the keys region-locked?

Accepted Answer

No. Microsoft retail product keys are not region-locked. A key purchased from LicenseVault activates Windows, Office, Server, SQL or Visual Studio in any Microsoft-supported language and country.

Question 5

Why is LicenseVault cheaper than the Microsoft Store?

Accepted Answer

LicenseVault sources surplus retail and unused volume keys through authorised EU resale channels and operates without first-party retail overhead. The keys are identical genuine Microsoft retail product keys — not OEM stickers, not MAK-shared, not grey-market.

Question 6

Which payment methods are accepted?

Accepted Answer

Visa, Mastercard, American Express, Discover, Apple Pay, Google Pay, PayPal, and instant SEPA / bank transfer — all via Stripe (PCI-DSS Level 1, TLS 1.3).

Question 7

In which languages is LicenseVault available?

Accepted Answer

The storefront is available in English, Spanish, German and French. Customer support replies in English, French, German, Spanish, Italian, Portuguese, Dutch and Arabic. The daily magazine publishes in 22 languages.
