Hello, in the last week, whenever I turn on my desktop computer (Dell XPS 8700, running Windows 10 v.1709 OS build 16299.64)  a popup stating "A digitally signed driver is required npf.sys (NT5/6 AMD64) Kernal Driver Riverbed Techonolgy,inc"  (shown in attachment) pops up as a warning about every 5 minutes and it is driving me crazy!  I have updated all my drivers and it STILL shows up. I tried finding the program that the driver is using to no avail.  If this driver is not necessary for any programs I have, I would like to delete it altogether but I am not sure if it is essential for Windows 10 or not. 

 

Is there any way I can find out how to remove or update the drivers in question?

 

Thank you for any help you might be able to give me.

it's not a microsoft program so you can remove it.

 

To remove npf.sys Kernel driver from your computer, please follow the manual instructions below or use an automatic uninstaller product.

  1. Click the Windows Start Button. In Windows 8, look for Control Panel.
  2. Click Control Panel.
  3. Click Uninstall a program.
  4. Look for NetGroup Packet Filter Driver or WinPcap Packet Driver in the list of available programs.
  5. Click Uninstall.

sorry i cut those instruction from a webpage.

 

you need to look under the network and sharing.

then double click on the network adapters and select properties and you should see the listing in the box that says "connection uses the following options". and remove it from there.

I opened the network adapter and selected properties (even on the individual drivers) and did not see "connection uses the following options". 

 

Screen shot attached.

that's the device manager, wrong place!

 

open control panel, then network and sharing.

on the right side of screen about 1/3 way down, double click on your network adapter, then select properties in the bottom left.

 

then look in the window and you should see what your looking for.

Sorry, kinda new to this.  I opened up the net work and sharing but I didn't see the network adapter on the right. I attached a screen shot and I drew in red my choices.

 

Thanks for being patient with me!

how about:

in your search bar type "services.msc" and open it, find "WinCap Packet Filter" and then double click it and disable it to see if it goes a way.

 

then i'd do a reboot.

I finally found the driver (see attached screen shot). Should I delete npfs.sys?   Or is that a necessary program for Win 10?

it says it's like used with packet sniffers, not really needed unless you installed something specifically that uses it.  if you did it will just stop working and maybe throw up a warning about it.   if it was me I would move the file to another folder and reboot and see if you problem goes away.

 

then pay attention to see if anything programs give you an error when you try to start them.
