Stapsgewijze handleiding voor het activeren van Windows 11 met een retail-productsleutel — nieuwe installatie, upgrade van Windows 10, en probleemoplossing.
- Windows 11
- Activering
- Handleiding
Voordat u begint
U hebt het volgende nodig: de productsleutel van 25 tekens (xxxxx-xxxxx-xxxxx-xxxxx-xxxxx), een internetverbinding en 5 minuten tijd.
Als u een upgrade uitvoert van een originele Windows 10-licentie, hebt u mogelijk geen nieuwe sleutel nodig — Windows 11 neemt de Windows 10-activering automatisch over.
Stap 1 — Activeringsinstellingen openen
Druk op Win + I om Instellingen te openen. Ga naar Systeem → Activering. U ziet de huidige status — doorgaans 'Windows is niet geactiveerd' totdat u een sleutel invoert.
Stap 2 — Productsleutel wijzigen
Klik op 'Productsleutel wijzigen', voer de sleutel van 25 tekens in de door Microsoft aangegeven indeling in, klik op Volgende en vervolgens op Activeren.
Windows neemt contact op met de activeringsservers van Microsoft en bevestigt dit binnen enkele seconden. De activeringspagina schakelt over naar 'Windows is geactiveerd met een digitale licentie'.
Stap 3 — Koppelen aan uw Microsoft-account
Meld u na activering aan bij een Microsoft-account (Instellingen → Accounts → Uw gegevens). Hiermee koppelt u de digitale licentie aan uw account, zodat u opnieuw kunt activeren op dezelfde pc na een schone installatie of na hardwarewijzigingen.
Probleemoplossing
Fout 0xC004C003 (Ongeldige sleutel): controleer de sleutel opnieuw — hij bestaat uit 25 tekens zonder extra spaties. Open de e-mail precies zoals wij deze hebben verstuurd.
Fout 0x80072EE7 / 0x8007232B: de activeringsservers zijn niet bereikbaar. Controleer uw DNS-instellingen of VPN; activering vereist een directe verbinding met Microsoft.
Fout 0xC004F050 (Sleutel geblokkeerd): zeldzaam bij retail-sleutels. Stuur ons uw ordernummer per e-mail en wij vervangen de sleutel binnen een uur.
