If, like me, you enjoy testing and installing virtual machines, then you may need to use generic license keys. These keys will be useful for system installation, but they won't allow you to activate your version of Windows; for that, you'll need to purchase an official license. In the latest versions of Windows, you can now install Windows without a license key. To use the keys listed here (GVLK keys), you must have a KMS host already running in your deployment. You can also find Windows licenses at very good prices on Amazon or from our partner Whokey. Windows 11 Pro OEM – €20.17 (with 25% promo code: tech2tech)
