Windows comes with thousands of utility services. Behind the scenes, it processes different utilities to accomplish various tasks at a time. Killer Network Service is one of those utility services that runs in the background.

Although the utility tool isn’t available on all regular Windows, you will find it on systems with Intel processors. It has been designed to monitor network connections and enhance the gaming experience.

Unfortunately, it has been a cause of high CPU and RAM usage for many users, which is a matter of concern. Therefore, we have some proven troubleshooting methods to fix Killer Network Service’s high CPU usage.

What is Killer Network Service?

Killer Network Service (KNS) is a utility service that works in the background of the Windows system. Its primary objective is to provide an excellent online experience.

KNS is integrated with a series of Intel Killer Wi-Fi cards, commonly seen on high-end PCs and gaming laptops. It helps to analyze network connections and reduce latency. Also, it comes in very handy to eliminate network lag.

Is KNS Bad for Our PC?

Absolutely not, Killer Network Service isn’t bad for our PC. It’s a fine service by Intel WiFi cards that helps improve our network connection in various ways: it reduces network latency, provides maximum bandwidth & minimizes lags.

When it eats the CPU, people start panicking about something bad happening inside the system, in reality, it’s totally the opposite. During periods of high CPU usage, KNS analyzes network traffic and optimizes the network accordingly.

Is Killer Network Service a Virus?

Killer Network Service is not a virus. As I already stated, it’s a network utility that you can find working silently on Task Manager to provide a good network service.
