I recently installed Microsoft Loopback Adapter in Windows 8 for networking between by Hyper-V host and client Virtual Machines. Below is the step-by-step guide to setup Loopback Adapter in Windows 8.
My environment consists of:
- Hardware – ASUS Laptop, 8GB RAM, 1TB HDD
- Software – Windows 8 Pro 64-bit (Hyper-V role enabled)
- Networking – Wired LAN and Wireless LAN (I want to network between Host and Client without connecting the wired/wireless networks)
Before I begin with the steps, let me inform you that Microsoft Loopback Adapter is now renamed as Microsoft KM-TEST Loopback Adapter in Windows 8 / Windows Server 2012. I am not sure why did Microsoft changed the name of this adapter now. This KB article gives the official details about the name change.
Step by Step Instructions:
- Launch the Add Hardware Wizard from control panel. Being a keyboard user, I prefer Win+R (for run command window) and type hdwwiz command.

- This will bring up the Add Hardware wizard.

- Click Next, to Continue.

- Select “Install the hardware that I manually select from a list (Advanced)” as shown above and click Next.

- In the above screen, select “Network adapters” option (as shown above) and click Next.

- In the “Select Network Adapter” screen, select Microsoft as the Manufacturer and then choose “Microsoft KM-TEST Loopback Adapter” and click Next.

- The above confirmation screen will appear. Click the Next button to continue.

- The installation step proceeds by showing the file copy progress bar indicator (as shown above)

- The above is the last screen of Add Hardware wizard, which indicates that the Microsoft KM-TEST Loopback Adapter is installed successfully.
Once these steps are completed, you can go ahead and assign a local IP address to this adapter. I am using this Lo0pback Adapter to use Remote Desktop Client to a SharePoint Virtual Machine which is running in Hyper-V. I will be sharing more details about this in my future blog post.
