The Microsoft Loopback adapter is a testing tool for a virtual network environment where network access is not available. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information. You can also install the Loopback adapter during the unattended installation process.

To installa  Microsoft Loopback adapter in WIndows 7

1. Click Start – Search for cmd, right-click cmd and select “Run as Administrator”
2. From the command prompt, run “hdwwiz.exe“. This should launch the “Add Hardware Wizard“. Click Next.

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

4. Now from the list select Network Adapters and click Next.

5. Under Manufacturers, select Microsoft and select “Microsoft Loopback Adapter” under Network Adapter and click Next. This should start the installation. Click Finish when the installation completes.
