Hi Phan
I'm AnnaThomas and I'd be happy to help you with your question. In this Forum, we are Microsoft consumers just like yourself.
You will have to contact Microsoft support to check if a product key is still valid
https://support.microsoft.com/home/contact?linkquery=product%20key Click on contact support at the bottom Choose the product and services related to the issue and also the category Click on Confirm Then click on Chat with a support agent in your web browser
I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.
Best Regards,
AnnaThomas
