hi,

i am no longer able to access my original VMWare Fusion virtual machine that I configured a windows 11 product key because I lost the decryption password. so I created a duplicate of the original VM using VMWare's option to create a new one using an existing VM. however, the new Microsoft sees the new VM as a new device and won't let me reuse the my product key bc it is already in use.

how can I get Microsoft to allow me to reuse the my windows 11 product key?

thanks,

I finally found a way to do it through the activation process inside of windows: settings->activation.

    Hi Vincent J. Buonassisi,

    Thank you for the update. I’m glad to hear that you were able to resolve the issue and reactivate Windows through Settings > System > Activation.
