Windows 10: My product key is not working

My product key had somehow changed to some organization, so tried entering my original product key but it says it doesn't work with error code 0xc004f50. I know the product key I am entering is my real product key but it is still showing this error

:)

Hi,

Thank you for posting your query in Microsoft Community. Appreciate your interest in using Windows 10.

I suggest you to try to activate Windows by phone by following the steps below:

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select your Region/Country.
• Select the Phone Activation option, and hold on for a real person.

Hope the information is helpful. Feel free to

Where is my Product Key if I want to re-install?


Like davidhk said. But if you really want to see your windows key, I would suggest Belarc advisor. It will give you some useful information about your system, product keys of your software is among them (not only Microsoft, you will have listed most of your keys).
