Service Not Running


Error: Service Not Running

You may experience a situation where their Killer Control Center says "Service Not Running" instead of operating normally. 

service not running



This can often be resolved by simply restarting the machine by clicking Start > Power > Restart, especially if the Killer Control Center has recently been updated. 

In Windows, services start before anything else, including other programs. If the service does not start automatically when the machine starts, then there is likely another service that is preventing it from starting, or the service is not set to start automatically

You can check to make sure that the service is set to run automatically by following these steps:

  1. Click Start, type services.msc and press Enter.
  2. Scroll until you find the Killer Network Service and double-click it.
  3. Make sure the "Startup Type" is set to Automatic. You can also manually start it from here by clicking Start button, which will clear the error until you next restart your machine.

If it was already set to automatic, make sure you are using the latest Killer Control Center, found here - For most users, this should fix the issue. If you have any issues installing the latest Killer Control Center, please refer to our installation troubleshooting KB here -

Some users may still encounter the issue after updating to the latest version of the Killer Control Center. We are aware of the issue, and we are currently working on an update to address it. In the meantime, you have a few options:

  • Ignore the Killer Control Center, for the time being. The error will disable all functions of the Killer Control Center, including all bandwidth optimization, but this may or may not be an inconvenience to you, depending on your usage. The network adapter(s) will otherwise continue to operate normally.
  • Start the service manually. This will only need to be done when the computer is rebooted, not when it is slept. 
  • Contact us here - - for a batch file that you can place in your startup folder that will start the service after Windows has completed booting. Depending on your security settings, this may require confirmation, so the process may not be entirely automated. 

We apologize for this temporary inconvenience. 



Problems With The Killer Network Manager


The Killer Network Manager is our outgoing performance suite. It is no longer being updated, and does not contain the latest Ethernet or Wi-Fi drivers. We encourage all users of the Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500 to upgrade to the Killer Control Center, found here - This includes users whose machines came with the Killer Network Manager preinstalled. There is no need to continue using the Killer Network Manager.

For a smooth installation, download the latest Killer Control Center installation package, then uninstall all Killer products from your Apps and Features menu, which is accessible by right-clicking Start, then restart your computer, and double-click the new installation package to install the new Killer Control Center.

The old Killer Network Manager suite is still available for download here - - but will no longer be updated, and may not be fully compatible with future Windows updates, antivirus suites, or other applications that manipulate network data.
