Häufige Fragen

How quickly do I receive the license key?

Immediately by email after receipt of payment, usually within a few minutes. If no email arrives, please check your spam/junk folder.

Can I upgrade from Windows 10 Pro to Windows 11 Pro?

Yes, with a Windows 11 Pro license. An in-place upgrade works if your device meets the Windows 11 hardware requirements (TPM 2.0, compatible CPU). Local data and programs are generally retained.

What if activation doesn't work?

You contact our support (live chat, phone +41 800 20 00 07). In most cases the problem is solved within 5 minutes, often via Microsoft phone activation. If the problem cannot be resolved permanently: replacement key or money back.
