• Client Hyper-V is the virtualization technology built into Windows 10 and Windows 8.x. It is the same virtualization technology previously available only in Windows Server. Client Hyper-V enables you to run more than one 32-bit or 64-bit x86 operating system at the same time on the same host computer. But instead of working directly with the computer’s hardware, the operating systems run inside a virtual machine (VM). Hyper-V enables developers and IT professionals to easily maintain multiple test environments. It also provides a simple mechanism to quickly switch between these environments quickly.
