Good to know before you buy Windows 11 Pro for Workstations
Windows 11 a des exigences matérielles – notamment TPM 2.0, Secure Boot et un processeur compatible.

La clé ne peut être activée que sur un seul PC et reste associée à cette machine ; une réinstallation ou un réinitialisation du même PC sont donc incluses dans le prix.
