Are Killer Network Service and Killer Analytics Service
throttling your upload speed from 100 Mbps down to just 1 Mbps?
KillerKiller automatically terminates these processes and keeps them gone forever.
Upload speed throttled
Full speed unlocked!
Killer Network adapters come with "optimization" software that actually throttles your speed
This background process claims to "optimize" your network but actually limits your upload bandwidth to around 1 Mbps, even if you have 100+ Mbps available.
Collects telemetry and further restricts bandwidth. Combined with the Network Service, your upload speed gets absolutely destroyed.
Even if you manually kill these processes in Task Manager, they restart automatically. You'd have to kill them every single time you boot your computer.
You're paying for 100 Mbps upload but only getting 1 Mbps. That's 99% of your bandwidth wasted because of bloatware!
"I was pulling my hair out trying to figure out why my uploads were so slow. Turns out Killer Network Service was the culprit. KillerKiller solved it in seconds!"

Open Task Manager (Ctrl+Shift+Esc), go to the Details tab, and look for "Killer Network Service" or "Killer Analytics Service". If you have a Killer-branded network adapter (common in gaming PCs/laptops), you likely have these processes.
No! These processes are just bloatware that LIMITS your speed. Your network adapter works perfectly fine (actually better!) without them running.

After purchase, you'll receive a download link and your license key. Run the activation script, then run the installation script as Administrator. Takes less than 2 minutes. Full instructions included.
Yes! Run the deactivation script on your old computer, then activate the same license key on your new computer. Licenses are transferable and can be used on one machine at a time.
