I already claimed the key: if you purchased the wrong version of Windows/Office and you discovered it after claiming the key, during the installation process, etc., please contact our support team.

I haven’t claimed the key yet: if you have noticed that the purchased version of Windows/Office is wrong, and you haven’t claimed the key yet, in the Kinguin Inventory you have the option to review what you purchased and return the product within 24h from the purchase date in exchange for Kinguin Balance. After that, please contact our support.
