Hi, in my Windows appliaction I have a license based on hardware ID, so that one licence is viable only for one computer. This works pretty well, but if Windows is running in PD, after every update I have generate new license. That is not the case in other virtualization software. Unfortunatelly, I missed the opportunity of logging with last big update, so can you tell me what is changing? I use CPU Id (unique ID), its clock speed, BIOS id and base board ID. thanks in advance
