Buying "used" Windows keys on Kinguin: Yes, it works (with a caveat)

[Redaktion]

Buying Windows keys directly from Microsoft is expensive but more importantly, it's just not an option for older operating systems such as Windows 8.1 or Windows 7. This is where platforms like G2A and Kinguin come in as they allow one to buy legit, working keys for a fraction of the original price.
