Activation troubleshooter requires you to have a digital license linked to a Microsoft Account. Also, bear in mind that activation depends on the type of Windows license for your device. If Windows came pre-installed with the computer, then the device has an OEM license. For an OEM license, the license dies as soon as the MOBO dies. So, essentially, it is non-transferable. If that is the case, you need to get a new license. However, if you purchased the license through the Microsoft Store, then that’s a Retail license, and it does carry transfer rights.
2] Enter the correct and genuine product key
In some cases, this issue occurs because the PC user have entered the incorrect product key and Windows fails to identify it. In this case, ensure you enter the correct and genuine product key. You can check the email that came with the digital download when you purchased from the Microsoft Store or any authorized reseller like Amazon.
