Hello, Finance Evident
Welcome to Microsoft Community.
If you’re unsure or encounter issues about product key, Microsoft Support (How to Contact Us - Microsoft Support) is the best place to resolve them. They can help you verify if the product key has been used and guide you through any necessary steps.
It’s important to keep your product key confidential and only use official Microsoft channels to verify its status.
