To (re)-install Windows 10 with retail or OEM media (including the Windows 10 media creator), you can (temporarily) use the "generic" installation keys, officially provided by Microsoft.
These keys allow you to perform the installation, after which Windows will run in a 30-day trial mode, before a proper key and activation is required. The keys are language and platform-independent.
