VMware Player can be used to have a computer inside another one. You’ll be able to run a new computer inside a window in your Operating System.
VMware Player will let you run virtual appliances created by VMware Workstation, GSX Server or ESX Server. You can download Virtual Appliances for free in the Internet.
It is always useful having a Virtual Appliance if you wish to install some software which you think might be harmful for your PC, test PC components or run tests which could be harmful for our Operating System.
You can set which resources you want it VMware Player to consume, making sure the PC will work fine.
