What is the requirement to deploy virtual machines on a Windows 10 desktop?

To deploy virtual machines on a Windows 10 desktop, the installation of a Type-2 hypervisor is essential. A Type-2 hypervisor, such as VMware Workstation or Oracle VirtualBox, operates on top of the host operating system, in this case, Windows 10, and allows the user to create and manage virtual machines. This type of hypervisor leverages the resources of the host system to run guest operating systems in isolated environments.

While other options may involve hardware or software adjustments, they are not specifically required for the deployment of virtual machines. For instance, adding a CD-ROM might be relevant for certain types of installations or configurations, but it does not address the core requirement of virtualization itself. Similarly, installing Windows patches helps maintain system security and performance but is not a direct requirement for setting up a hypervisor. Lastly, adding an additional network interface could enhance networking capabilities for virtual machines but is not a prerequisite for their deployment.

By installing a Type-2 hypervisor, users can effectively manage multiple operating systems simultaneously, which is the fundamental purpose of virtualizing on a Windows 10 environment.
