Thank you very much for the question!
From a previous investigation, WIBU support team suggested that the detection of the Virtual Machine itself is correct, but due to a default MS configuration, Surface Books run with Hyper-V activated.
The developer referred to the following discussion: https://answers.microsoft.com/en-us/surface/forum/all/how-to-enable-vt-x-on-surface-book-3/b9057c59-...
Here it's also roughly described why WIBU detected surface books as VMs, as the virtualization layer is activated by default on such systems. Therefore currently for Surface Books, please deactivate Hyper-V and see if it helps with the issue. If it doesn't work, please contact your local support for further assistance.
Thank you very much for your understanding, and I am very sorry for the inconvenience! Please let me know if you have any further questions!
