Microsoft Hyperv Network Switch Default Miniport Driver Windows 81 16

Microsoft Hyper-V Network Switch Default Miniport Driver Windows 8.1 16

The Microsoft Hyper-V Network Switch Default Miniport Driver is a system driver that is installed by default on Windows 8.1 and later versions of Windows that support Hyper-V. It is used to create and manage virtual switches for Hyper-V virtual machines. A virtual switch allows virtual machines to communicate with other computers on the same or different networks.


The Microsoft Hyper-V Network Switch Default Miniport Driver has a version number of 16, which indicates that it supports the latest features and enhancements of Hyper-V in Windows 8.1. Some of these features include:

  • Extensible switch: The Hyper-V extensible switch allows third-party extensions to plug into the switch and provide additional functionality, such as security, monitoring, filtering, and forwarding. The extensible switch also supports standard port policies, such as VLAN identification and access control lists.

  • Network virtualization: The Hyper-V network virtualization allows multiple virtual networks to be created and isolated on the same physical network, using a technique called network address translation (NAT). This enables multiple tenants to share the same network infrastructure without compromising security or performance.

  • Quality of service (QoS): The Hyper-V QoS allows administrators to define bandwidth limits and priorities for different types of network traffic, such as live migration, storage, or management. This ensures that critical traffic is not affected by congestion or interference.

  • Dynamic virtual machine queue (DVMQ): The Hyper-V DVMQ allows the network adapter to distribute incoming packets to multiple processors, based on the destination virtual machine. This improves the scalability and performance of network-intensive workloads.

  • Single root I/O virtualization (SR-IOV): The Hyper-V SR-IOV allows a physical network adapter to be directly assigned to a virtual machine, bypassing the virtual switch and the host operating system. This reduces the overhead and latency of network communication and increases the throughput and efficiency.

The Microsoft Hyper-V Network Switch Default Miniport Driver can be updated through Windows Update or manually downloaded from the Microsoft website. It is recommended to keep the driver up to date to ensure compatibility and stability with Hyper-V and its features.

To create and configure a virtual switch using Hyper-V Manager or PowerShell, follow the steps in this article. To learn more about the types and properties of extensible switch ports, refer to this article.
