WinPcap - what is this program and is it needed?

WinPcap 4.1.2 - what is this utility?

Most of all, WinPcap is needed by programmers, so ordinary users can immediately get rid of it. In this case , after uninstalling it is worth cleaning the device from possible viruses if the utility was not installed from the official website.

The program is a consolidated library that allows applications installed on a computer to receive and transmit network packets, which, evading protocols, go to the network card. The system is popular among programmers as an essential utility for capturing packets and filtering a myriad of network tools, commercial or open source, such as protocol analyzers and network monitors. They have the function of storing data about intrusions into the user's system, monitor traffic generators and have many other responsibilities.

WinPcap 4.1.2 is available only for owners of the Windows operating system. WinPcap for Windows 10 is slightly different from the original and is called Win10Pcap. Among the differences in the operation of the program, we can highlight compatibility with NDIS driver models 6.x, which work correctly with the Windows 10 operating system. You can download Win10Pcap on the official website. In the same way, you can find and download the WinPcap 4.1.2 utility for Windows 7 from the official website for free and in Russian.

Beware of downloading programs from unverified sources! Along with the utility, installation files may bring viruses that infect the device.

How to properly uninstall WinPcap?

Another undesirable property of the program is that it categorically does not want to be removed from the computer. No, if you run the built-in uninstaller through the menu “Control Panel” - “Uninstall a program”

, the program will be deleted, however, it will leave behind a lot of files, folders and registry entries, which may subsequently interfere with the correct operation of the operating system.

In this case, we recommend performing a comprehensive removal of WinPcap, which can be provided by the Revo Uninstaller program.

Your actions will be simple: you will need to run Revo Uninstaller, after which a list of installed programs will be displayed on the screen, among which you will need to find WinPcap, right-click on it and select “Uninstall”

First, the program will create a restore point in case the computer does not work correctly after uninstallation. Once the procedure is completed, the system will automatically launch the WinPcap uninstaller and you will need to perform a normal program uninstall.

Once the uninstallation is complete, Revo Uninstaller will prompt you to scan your system to identify and remove residual WinPcap files. We recommend performing an advanced scan - although it will take longer, the program will be able to find the maximum number of remaining traces.

After you finish working with Revo Uninstaller, you will need to restart your computer so that the system can finally accept the changes made. From this point on, the removal of the WinPcap program can be considered complete.

WinPcap 4.1.2 features

A large number of network programs use sockets (a port number along with an IP address) to gain access to a user's network. This provides access to low-level data processed by Windows. However, not all network applications are happy with this kind of access; they need raw, original data to work correctly. When regular sockets are not enough, it becomes necessary to download WinPcap. Its main advantages are:

capturing raw packets;
filtering received packets;
sending initial data to the network;
collecting information about network traffic.

The program acquires these functions thanks to a special driver and .dll libraries.

Removing WinPcap

Once installed, the program is usually located at

This folder contains three files, one of which, Uninstall.exe, is responsible for uninstalling the utility. This means that by launching it, you will begin the erasing process.

In general, it is better to use specialized software to remove all kinds of software; for example, I use Revo Uninstaller. I wrote about this here.

Often, the utility installs its extensions in browsers, which it also doesn’t hurt to get rid of. Let's say, if you use Google Chrome, then you need to go to “Settings - Additional tools - Extensions”, find unnecessary ones among them and delete them. A similar principle should be followed in other browsers.

That's all on this topic. I hope I answered you as clearly as possible about what kind of winpcap program this is. If not, write in the comments.

I promise to prepare new useful articles for you, so I hope to see you on the pages of my site soon.

Often the WinPcap program ends up on a computer as an addition to user-downloaded software such as WireShark, so many computer owners think about the benefits of the installed utility. In addition, among ordinary Windows users, the application is famous for its function of tracking the actions performed by the owner and from time to time redirecting it to pages with advertising, which can easily infuriate. WinPcap - what kind of program is it, is it really harmful to the computer and is it worth installing?

Cons of WinPcap 4.1.2

Reception and further transmission of packets is carried out by the program without taking into account host protocols, so WinPcap 4.1.2 does not have the ability to manipulate traffic produced by other applications on the computer, filter it or block it. Thus, WinPcap 4.1.2 will not have proper support for Windows applications such as:

QoS scheduler;
firewall (protects the device from the threat of hackers and viruses);
shaping (traffic limitation for a network node).
