Which Windows editions we carry

The most common question about Windows is Pro or Home. In short: if you need BitLocker encryption, virtualisation, corporate network integration or Remote Desktop Server, Pro is the only option. Otherwise Home is sufficient and is cheaper.

Selbst prüfen

Den Händler können Sie selbst prüfen, in zwei Minuten

Wer hinter einem Shop steht, ist öffentlich nachprüfbar: ein seriöser Händler hat eine echte Firma mit Registereintrag und gültiger USt-IdNr., beides einsehbar. Die Herkunft eines einzelnen Keys lässt sich von aussen zwar nicht belegen, wohl aber, ob hinter dem Shop eine fassbare Firma steht. Bei uns geht das sogar live, gleich hier.

Häufige Fragen

Which Windows edition do I need?

For private use, Windows 11 Home is sufficient. You need Windows 11 Pro if you require BitLocker, Hyper-V, Remote Desktop Server or a corporate network connection.

Can I switch from Windows 10 to Windows 11?

Yes, provided your device meets the Windows 11 hardware requirements (TPM 2.0, compatible CPU). With a Windows 11 licence from us, the in-place upgrade usually works without data loss.

What happens if Windows activation fails?

Our German-speaking technical support helps you free of charge. If the problem cannot be resolved permanently, you receive a replacement key or your money back.
