`net start npf` works for me, thanks!

Still wondering, what is npf anyway?
It’s nowhere in services.msc, nor `wmic service list`.

The way that worked for me was:
Right Click on Short Cut, Properties, Compatability Tab, where it says Privilege Level, tick “run this program as an administrator”.

Works OK. Win 7, installed Wireshark, worked fine the first time the program is runned. Turn off the PC, turn on, start Wireshark and since then message “NPF driver not found” is shown.

Tried : “net start npf” from command prompt, but doesnt work, says “Access denied”.

Right click on shortcut, properties, enable “run as admin”, ok. Then click on shortcut and goes OK.

By running as an administrator i am able to find the interfaces but the packet sniffing does not show up, kindly share your thoughts.
