Hyper-V is a type-1 (bare-metal) hypervisor developed by Microsoft. It is included in Windows Server 2008 R2 and later as well as Pro editions of desktop Windows since Windows 8. Hyper-V separates the host operating system and clients using partitions which run on top of a core hypervisor layer and includes many enterprise-oriented features including live migration and memory ballooning. Hyper-V virtual machines can be managed using the Hyper-V Manager MMC snap-in.

On desktop versions of Windows, the hypervisor is officially named Client Hyper-V. It replaces Windows Virtual PC in Windows 7, but does not provide Windows XP Mode.
