How Do I Update or Install the Killer Control Center


You can find the latest Killer Control Center, as well as the latest drivers for your Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500, here -

The installer will automatically detect and install on any 64-bit version of Windows 7, 8.1, and Windows 10.

If you are using an older version of our suite, such as the Killer Network Manager, or you have not updated your network adapter drivers since your last Windows feature update (for example: Anniversary Update, Creator’s Update), then we suggest downloading the Killer Control Center, but uninstalling any application with the "Killer" name from your Apps and Features menu (accessible by right-clicking Start) and restarting your machine before installing the Killer Control Center.


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, then the next step will be to find out why it did not start. The primary culprit is usually an antivirus or firewall program. If you are running an antivirus or firewall program, try temporarily uninstalling it, and reboot to see if that solves the issue. Unfortunately, simply disabling an antivirus or firewall program will not stop its service from loading - they must be temporarily uninstalled in order to troubleshoot.

If uninstalling the antivirus or firewall program solves the issue, try reinstalling it with a fresh copy downloaded from your antivirus program's vendor, then restarting your machine. You might find that simply reinstalling the program does the trick. Alternatively, it may block the service from starting again.

If you find that using the latest version of an antivirus program causes our service to not start when your machine boots up, please contact our support here - Please let us know which antivirus or firewall suite you are using, and which troubleshooting steps you have taken so far.

However, if the service does not start even with no antivirus or firewall programs installed, try uninstalling and reinstalling our suite by following these steps:

  1. Download the latest Killer Control Center from here - - and save it somewhere handy.
  2. Right-click Start
  3. Click Apps and Features
  4. Find and uninstall everything with "Killer" in it, including "Killer Drivers" and "Killer Performance Suite" and any variations. 
  5. Restart your machine by clicking Start > Power > Restart
  6. Once your machine is back up, double-click the installer for the Killer Control Center that you downloaded.
  7. When the installer has completed, restart your machine.
  8. When your machine is back up, load the Killer Control Center, and check to see if it is operating normally.

If the Killer Control Center still reports "Service Not Running," please contact support here - Please let us know that you have followed all troubleshooting options in this knowledgebase article, and any other troubleshooting steps that you have taken, if any. 


What Is the Difference Between the Killer Control Center and the Killer Network Manager?


The Killer Network Manager is our older, outgoing network prioritization suite. The Killer Control Center is much more optimized for current builds of Windows 10, and even some security changes to older versions of Windows, and will be the only performance suite that will be updated going forward. As Microsoft continues to make changes to their operating system, the Killer Network Manager will become less usable. We recommend all users switch to the Killer Control Center as soon as possible, regardless of which software their machine originally shipped. The best course of action is to download the latest Killer Control Center, found here - - then, in your Apps and Features menu, uninstall any Killer Drivers or Killer Performance Suite entries that you see, restart your machine, and then run the installer for the Killer Control Center. If you encounter any issues, you can contact support at


Do I Need the Killer Control Center?


The Killer Control Center is the program that examines your applications, and sets priority so that your most speed-critical applications get first access to your bandwidth. Without it, every application that uses your Internet connection gets equal treatment, which can cause noticeably slower speeds.

For example, say you are playing a data-intensive game, also streaming a YouTube video, and downloading a large file. Without the Killer Control Center, your game might have issues as it has to share its bandwidth equally. With the Killer Control Center, the game will be given all the bandwidth it wants, while the video is slowed (which just means it'll likely buffer a bit more to start, and then work perfectly), and your download is the lowest priority.

Will the adapter work without the Control Center, running only the .INF version of the drivers? Certainly, but you are missing out on its most important features!

In summary, if you want to make the most of your Internet connection, you will want to use the Killer Control Center.
