Occasionally you may not be able to remove a network adapter using the remove button in Control Panel\Network. If this happens you can remove the registry keys for that adapter.


Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
  1. Start Registry Editor (REGEDT32.EXE).
  2. From the

    subtree remove the following subkeys:

    • \SOFTWARE\Microsoft\adapter
    • \SOFTWARE\Microsoft\WindowsNT\CurrentVersion\NetworkCards\# (If only one adapter is loaded, # will be 1)
    • \SYSTEM\CurrentControlSet\Services\adapter
  3. Quit Registry Editor and reboot.
