GNS3 VM On Hyper-V

With Windows 10 Pro, you have the option of using a Windows native hypervisor called Hyper-V. It’s included with the OS so you don’t have to pay the high price of something like VMWare Workstation while still getting great performance. I set it up with the default option of using Dynamic Memory so that it won’t use much ram until you start adding a lot of routers and switches and it will scale up the VM’s available RAM as needed.
