title: Installing NPF Driver Manually
body: <p>I want install NPF driver without Packet.dll and wpcap.dll.
  I extract Winpcap-4.1.exe using 7zip and copy npf.sys to C:/Windows/ System32/drivers.
  I also have made such registry</p>
  
  <blockquote>
    <p>Windows Registry Editor Version 5.00</p>
    
    <p>[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ services \ NPF]
    "Type" = dword: 00000001 "Start" = dword: 00000002 "ErrorControl" =
    dword: 00000001 "ImagePath" = hex (2):
    73,00,79,00,73,00,74,00,65,00,6d, 00,33,00,32,00,5c, 00,64,00, \<br>
    72,00,69,00,76,00,65,00,72,00,73,00,5c, 00,6e, 00,70,00,66,00,2e,
    00,73,00,79, \    00,73,00,00,00 "DisplayName" = "NetGroup Packet
    Filter Driver" "TimestampMode" = dword: 00000000</p>
    
    <p>[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ services \ NPF \
    Enum] "0" = "Root \ \ LEGACY_NPF 0000" "Count" = dword: 00000001
