Windows 10 Creators update - Activation problem?

I recently updated to  Windows 10 Creators Edition on a Bootcamp partition which, before the update, worked fine, both natively and with Fusion 8.5.8 as a virtual machine.

After updating to Windows 10 Creators Edition my Bootcamp partition and my virtual machine said that Windows was not activated.

I contacted Microsoft Support and eventually they got my native Bootcamp partition activated but my Virtual machine still says Windows is not activated.

Is this a known problem and does anyone have a solution to this?

Regards,

Bernard
