Windows 10: activation key will not work

bought new windows 10 and it will not accept the activation key provided.

If it is a UEFI Bios you shouldn't have to enter the key at all. If it is you will have to enter your key again and run activation. Even if you do swap boards the key will work.

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.
