Coming from a Windows 10 Home, I changed my motherboard to be able to install Windows 11 Home and activate it successfully. Recently I updated my MSI bios and now I can't activate my Windows 11 Home, even by using the product key I had on my windows 11 Home,

Any advice ?

Thank you.

    Hi ,

    Do you buy the product key separately or does it come with the computer?

    Thanks

    It came with the previous motherboard computer and it was activated on the new motherboard

    successfully, until I updated the BIOS

    Hi ,

    I'm asking if you purchased the license separately because if your license came with the computer, it's very likely an OEM license. This type of license is tied to the computer's motherboard. If you replace it with a different one, unfortunately, you'll lose the license and have to buy a new one.

    If you purchased the license separately (Retail) and tried hardware activation, but it didn't work, you'll need to contact Microsoft support to verify the activation.

    Give feedback if the information was useful or not.

    Thanks

    Hi Yvan, I understand the "tied to the computer" principle. But the "I changed hardware on this device recently" worked on my "new" computer because its linked to my microsoft account. So the product KEY was successfully transfered to my new computer . For some reason it stopped working after the BIOS update

    Thanks
