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 (3 July 2012). Source: https://licensevault.net/about ### Why is LicenseVault cheaper than the Microsoft Store? Because LicenseVault sources surplus retail and unused volume keys through authorised EU resale channels and operates without the overhead of Microsoft's first-party retail price book. The keys are identical genuine Microsoft retail product keys — not OEM stickers, not MAK-shared, not grey-market. Source: https://licensevault.net/about ### How fast is delivery? Typical delivery is under 10 minutes, 24 hours a day, 7 days a week. The 90-day average is approximately 8 minutes. Keys are released automatically by email after Stripe captures payment. Source: https://licensevault.net/ ### What is the refund policy? 14-day free return on every purchase, in line with EU Directive 2011/83/EU (Consumer Rights Directive). Selected category landings offer a 30-day money-back guarantee. If a key ever fails to activate against Microsoft's servers, LicenseVault replaces it free of charge for the lifetime of the product. Source: https://licensevault.net/refund-policy ### Are the keys region-locked? 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. Source: https://licensevault.net/llms-full.txt ### Which payment methods are accepted? Visa, Mastercard, American Express, Discover, Apple Pay, Google Pay, PayPal, and instant SEPA / bank transfer — all via Stripe. Stripe is PCI-DSS Level 1 certified with TLS 1.3 end-to-end. ### Which currencies are supported? Storefront prices are quoted in EUR (€). Cards in any other currency are converted by the cardholder's issuing bank or by Stripe at the prevailing rate. ### What is the difference between OEM and retail keys? OEM keys are permanently tied to the first motherboard they activate on and cannot be transferred. Retail keys can be moved to a replacement device and qualify for free Microsoft activation support. Both are genuine Microsoft keys and both activate against the same Microsoft servers. LicenseVault sells retail keys by default.

Office 2024 is a one-time perpetual purchase, installs offline, has no cloud quota, and never receives feature updates. Microsoft 365 is an annual subscription with always-latest apps, 1 TB OneDrive per user, multi-device install, and an optional Copilot add-on. Choose Office 2024 for cost predictability and offline use; choose Microsoft 365 for cloud collaboration and the newest features. Source: https://licensevault.net/compare/office-2024-vs-microsoft-365 ### Windows Server Standard vs Datacenter — which do I need? Standard licenses up to 2 OSEs (operating system environments) per host and is intended for low-density physical or lightly virtualised servers. Datacenter licenses unlimited OSEs per host and adds Software-Defined Networking, Storage Spaces Direct, Shielded VMs, hotpatching and GPU partitioning (2025). Choose Datacenter once you run 11+ VMs per host or need any of those advanced features. Source: https://licensevault.net/compare/server-standard-vs-datacenter ### SQL Server CAL vs Per-Core — which model is cheaper? Server+CAL is usually cheaper when the user/device count is small (roughly ≤ 50 known named users) and the workload is internal. Per-Core is required for any internet-facing workload and is cheaper at higher user counts because it caps cost by hardware, not headcount. Per-Core has a 4-core-per-processor minimum, sold in 2-core packs. Source: https://licensevault.net/guides/sql-server-cal-vs-core ### How do I fix activation error 0xC004C003? 0xC004C003 means "wrong edition for the installed product" — the installed Windows edition does not match the key. Install the matching edition (e.g. Windows 11 Pro for a Pro key) or request a replacement key from LicenseVault support.
