I've been on Parallels 12 and downloaded version 13 to give it a try. I decided to install Windows 10 and was totally disappointed by how PD 13 preconfigures the virtual machine. During the install it silently creates an admin user with my current Mac user name and there is no way to change this. So I can't see standard Windows 10 installation dialog and somehow PD decides for myself. I couldn't find any switch for such a behaviour. VERY disappointing. What the hell is that????
