1. Npf Driver Download
2. Wireshark Npf Driver Windows 10

Another issue is driver signing: in Windows 10 x64 that really will be changing, so it will be important for WinPcap to be updated before the RTM release - more about this here. Update 3-27-15: Do you want to use Wireshark on Windows 10? Tweet about this problem! Do a post about this issue. Bring it up at Sharkfest in June.

I just installed WireShark, which also installed WinPcap.

During the installation it said 'do you want xxx to start automatically', which I answered yes.

Now I would like to stop the service when I am not running wireshark, but cannot find a service in the list with name wireshark or winPcap.

Is there a service that I can stop? Or do I need uninstall WireShark?

The WinPCap services is known as 'NPF' (NetGroup Packet Filter), you can start/stop it on command line with

To find it in a GUI, you'll have to open 'Properties' for 'My Computer', then select the 'Hardware' tab, open 'Device Manager'.Here, select View -> Show hidden devices, open up Non-Plug and Play Drivers, right-click on NetGroup Packet Filter Driver and select Properties from the menu, thus you will get a 'NetGroup Packet Filter Driver Properties' window.

Other commands that may be of interest are:

Change NPF to run manually

sc config npf start= demand

Npf Driver Download

Change NPF to run automatically at boot

sc config npf start= auto

Though I've always found the command line method to be simpler, there is a GUI way to do this too.

In device manager, select 'Show Hidden Devices' on the view menu, then under 'Non-Plug and Play Drivers', the 'NetGroup Packet Filter Driver' is listed. Double-click or right-click and select 'Properties'

On the 'Driver' tab of the properties page, the current status and 'Start' or 'Stop' buttons are displayed.

• okay, I gave an attemp according to the above link, but no luck its still saying 'The NPF driver isn't running'
  while dng I got this doubt after extraction Packet.dll has 4 difft versions (Packet_1.dll, 2, 3, 4) in that I opened properties and checked the details
  (Packet.dll- NT5) (Packet_1.dll- Vista) (Packet_2.dll- Vista) (Packet_3.dll- NT5) (Packet_4.dll- NT4) so here first i copied the (Packet.dll- NT5) but didnt work so tried with (Packet_1.dll- Vista) and the other Vista one both but no luck
  so do u have any idea which one exactly I ned to copy ???
  • I've fixed this via copy File and some Powershell stuff.
    I've bypass that issue.
    I've capture the wincap installation.
    For a 32bits app running on a x64 OS, I've make a condition on the nfp.sys file, in order to copy the x64 amd sys file.
    Then with a Custom Action, I created a service using SC DOS command.
    ' sc create npf binPath= system32driversnpf.sys type= kernel start= auto error= normal tag= no DisplayName= ' NetGroup Packet Filter Driver '
    I used Powershell my CA. VBS script should be also working.
