Does Windows use VM’s cores if inactive?

I’m using Win10 and I’ve set up an Ubuntu VM, with 4 cores allocated and 8GB of RAM. I noticed that as soon as the VM starts it “takes” the allocated RAM (it’s listed as used in Task manager). However, in Task Manager I still see all cores of my CPU and it seems like Windows uses all of them if the VM is idle.

Is any of this true? Where can I learn more about this?

  1. Are you saying that you see all four cores in Task Manager even if the VM is doing nothing? That is how it’s supposed to work. Windows is acting like a regular computer, just virtualized.

  2. Nice username lol. No assigned cores are not reserved by your VM, that would kind of destroy thr whole point of virtualization. vCPUs are a process like every other process that gets a cpu cycles allocation.
