Windows 10: Changing Windows product key

When ever I try to change my windows product key, it comes up and says "The product key you entered didn't work. check the product key and try again, or enter a different one. (0xc004f050)" I don't know what else to do, I've tried trouble shooting but its nothing happens. I've made sure that I am inputting the right key several times.

Hi Andre,

Thank you for contacting Microsoft community.

I suggest you to Uninstall the license using the following steps.

• Press Windows key + X
• Click Command Prompt (Admin)
• At the command prompt, type: slmgr.vbs -upk
• Press Enter, this will uninstall the product key from the computer.

Further on, install Windows 8.1 activate the copy with the product key on the new machine. Then again upgrade the same to Windows 10 using Window Update or Media Creation Tool.
