· 5 min de lecture· Mis à jour le 2026-03-18Clés Windows OEM vs Retail
Les clés Windows OEM sont moins chères mais liées à une carte mère. Les clés Retail sont transférables. Voici exactement ce qui change et laquelle vous devriez acheter.
- Windows 11
- Licences
- Retail
La différence fonctionnelle
Une clé OEM est liée de façon permanente à la première carte mère sur laquelle elle est activée. Si vous remplacez la carte mère, l'activation est perdue. Vous devrez acheter une nouvelle clé.
Une clé Retail est transférable. Déplacez-la vers un nouveau PC en la désactivant sur l'ancien (ou en laissant Microsoft détecter automatiquement le changement de matériel après une connexion avec un compte Microsoft).
| Propriété | OEM | Retail |
|---|---|---|
| Transférable vers un nouveau PC | Non | Oui |
| Support direct Microsoft | Non | Oui |
| Liée à la carte mère | Oui | Non |
| Récupération après changement matériel | Appel manuel à MS, souvent refusé | Automatique via compte Microsoft |
| Prix indicatif (Win 11 Pro) | €7–€15 | €18–€30 |
| Usage en volume en entreprise | Autorisé uniquement sur matériel constructeur | Autorisé partout |
Prix et support
Les clés OEM sont moins chères car Microsoft les vend à prix réduit aux constructeurs de systèmes, avec pour contrepartie que Microsoft ne les prend pas en charge directement — le support est à la charge de l'OEM (vous).
Les clés Retail bénéficient du support direct Microsoft et sont légèrement plus chères en conséquence.
OEM en un coup d'œil
Pros
- Prix d'achat le plus bas
- Ensemble de fonctionnalités identique à Retail
- Activation instantanée
Cons
- Liée à une seule carte mère à vie
- Aucun support Microsoft
- Souvent désactivée par Microsoft en cas de revente
Laquelle acheter ici ?
Toutes les clés Windows que nous vendons sont Retail. Activation à vie, transférable vers un nouveau PC, liaison complète au compte Microsoft disponible.
Nous ne stockons délibérément pas de clés OEM — les économies ne valent pas le verrouillage de l'activation pour la plupart de nos clients.
Questions fréquentes
- Puis-je transférer une clé OEM depuis un PC en panne ?
- Officiellement, non. Microsoft lie les clés OEM à l'identifiant matériel de la première carte mère. En pratique, vous pouvez parfois appeler le support MS et expliquer la situation — ils peuvent réactiver une fois, mais ce n'est pas garanti.
- Une clé Retail est-elle la même qu'une clé « Full Packaged Product » (FPP) ?
- Oui. FPP est le terme interne de Microsoft pour la référence Retail en boîte. Mêmes droits d'activation, simplement livrée de façon électronique.
