Windows 10Pro requires re-activation

Installed Windows 10 Pro on Bootcamp - went well -
FYI - Macbook Pro 2018 MAC OS 10.13.6
I installed Parallels on top and went well -
but now I am getting "Windows needs activation" again and that it this key is "already used on another computer" -
Had to get on phone with MS technician to get Windows activated again -
He said that MS sees Windows running directly on Bootcamp and Windows being emulated on Parallels as two different hardware applications, even though it is just one installation and use -
Has anyone run into this and is there a fix?
