Trouver une clé OEM (Windows préinstallé)
Ouvrez l'invite de commandes en tant qu'administrateur et exécutez : wmic path softwarelicensingservice get OA3xOriginalProductKey. Cela extrait la clé que Microsoft a gravée dans votre BIOS en usine. Fonctionne sur tous les PC préassemblés vendus avec Windows.
Trouver une clé Retail
Les clés Retail ne sont généralement pas stockées sur le PC après l'activation. La licence numérique se trouve sur les serveurs Microsoft. Votre vraie « sauvegarde » est le compte Microsoft que vous avez utilisé pour activer.
Si vous avez acheté sur LicenseVault, votre clé figure dans votre e-mail de commande et dans l'historique de votre compte — retéléchargez-la à tout moment.
Sauvegardez la clé dans un endroit sûr
- · Idéal : gestionnaire de mots de passe (1Password, Bitwarden, KeePass) sous une entrée clairement nommée.
- · Acceptable : une copie imprimée dans votre classeur.
- · À éviter : un post-it sur le portable, le fond d'écran du bureau, un fichier texte non chiffré.
