Buy one Server OS license for upto 16 cores and you can run upto 2 VMs on the same ESXi host. Most just talk about VMs with a Server OS and that is pretty easy.

I've done some research and of course Desktop OS VM licensing is complicated and is all but hidden. I just use them to isolate customers applications and the different development software and or versions each project needs. I have been using my full retail Windows 10 Pro for VMs on my Windows 10 Dell laptop. It seems reasonable to me that I should be able to run as many Windows 10 VMs as I want as long as I'm the only one using them and others do not access and can not remote into them. I have a Dell laptop that came with a Windows 10 license.
