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.

  1. thanks ^_^

  2. resolved the problem yaar!
    it,s great………

  3. Great tutorial.

    Another method of accomplishing the same thing would be to launch Computer Properties and then click on Device Manager on the left pane. There are many ways to launch it but the best I like is to press “Win + Pause/Break” combination.

    In the Device Manager, click on one of the existing Network Adapters and then click on “Action” on the menu bar and select “Add legacy hardware” Voila!

    You get the same wizard again. Rest of the procedure is the same.

    I mean, you can do the same task by multiple methods because in actuality all of those method invoke some executable or dll in the background (all of which cannot be remembered of course) :-)
