- Comparatif
Les fonctionnalités qui font la différence
Home et Pro partagent le même noyau, la même interface, la même compatibilité applicative. La distinction porte uniquement sur les fonctionnalités professionnelles et avancées.
| Fonctionnalité | Home | Pro |
|---|---|---|
| Chiffrement de lecteur BitLocker | — | ✓ |
| Bureau à distance (hôte) | Client uniquement | ✓ hôte + client |
| Virtualisation Hyper-V | — | ✓ |
| Windows Sandbox | — | ✓ |
| Éditeur de stratégie de groupe | — | ✓ |
| Jonction domaine / Azure AD | — | ✓ |
| Accès attribué / Mode kiosque | — | ✓ |
| RAM maximale | 128 Go | 2 To |
| Création de compte local | Compte MS imposé | Optionnelle |
Quand Home suffit
Si votre journée se résume à la navigation, Office, les jeux, le streaming et une connexion avec un compte Microsoft, Home fait tout ce que Pro fait et vous économise ~€10.
Home en un coup d'œil
Pros
- Moins cher
- Performances identiques
- Toutes les applications grand public fonctionnent
Cons
- Pas de BitLocker
- Ne peut pas héberger le Bureau à distance
- Pas d'Hyper-V / fonctionnalités WSL2 entreprise
Quand Pro se rentabilise
Si vous travaillez à domicile et vous connectez à un PC de bureau, chiffrez une clé USB ou utilisez Docker Desktop (qui nécessite Hyper-V), Pro est indispensable — il n'existe aucune solution de contournement sur Home.
Questions fréquentes
- Puis-je rétrograder Pro vers Home ?
- Non, sans réinstallation propre. La mise à niveau est à sens unique.
- Windows 11 Pro for Workstations en vaut-il la peine ?
- Seulement si vous disposez de 4 sockets CPU ou plus, de 6 To+ de RAM ou utilisez des volumes ReFS. Pour tous les autres, la version Pro standard suffit.
- La clé Pro fonctionnera-t-elle si mon PC était livré avec Home préinstallé ?
- Oui. Microsoft remplace la licence numérique OEM Home par votre licence Retail Pro lors de l'activation.
