For better compatibility, the VMWare and VirtualBox virtualizers also offer extensions that have to be installed on the guest system so that, for example, USB 3.0 or switching to the guest system is possible using the mouse focus alone. Hypervisor programs such as Hyper-V, VMware Workstation, and Oracle VirtualBox are some popular ones that allow a virtual machine (VM) to run in isolation on a host system as if it were on a physical machine. However, this all doesn’t need anymore, we already have a technology called virtualization achieved using different hypervisor platforms for Windows, Mac OS, and Linux. Well, this whole procedure is not only time-consuming and error-prone, moreover, if you don’t know how to do it properly it can even cause a breakdown of the system’s current OS. For example, we have Windows 10 PC and want to try Ubuntu Linux, in such a scenario either you can set a boot manager that offers a selection of which operating system should be started when the system is booted. Generally, on our PC or Laptop, we have only one operating system either Windows or Linux, however, what happens if we want to try out some other OS. Which Virtual Machine should you use on Windows 10? What is a virtual machine?
