Frequently asked questions about Windows operating system licenses

Is it legal to buy used Windows licenses?

Yes. The trade in used software licenses is expressly permitted in the EU by the ECJ ruling of July 3, 2012 (Case C-128/11, UsedSoft). At Lizenzindustrie, you receive only legally compliant Windows licenses.

What is the difference between OEM and retail licenses?

OEM licenses are tied to a specific PC and are non-transferable. Retail licenses can be transferred to a new computer. For maximum flexibility, we recommend retail licenses.

Can I upgrade from Windows 10 to Windows 11?

Yes – if your hardware meets the system requirements (TPM 2.0, UEFI, 64-bit CPU). The upgrade from Windows 10 to Windows 11 is available free of charge to existing users via Windows Update.

How do I receive my license key?

After purchase, you will receive your activation key immediately via email. Activation takes place directly through the Microsoft activation servers—quickly, easily, and without any technical knowledge required.
