I tried disabling the startup entry for Killer Intelligence Center to see if it affected my connection to the internet. Immediately after a restart, the KIC and several other Killer tasks were gone from Task Manager, I had regained about 10% of my memory availability, and I connected to my ethernet and got online ok. By the time I got to Speedtest.net, the KIC and its cohort of tasks were back in Task Manager, and memory usage went up from 20% to 30%! Does anyone know how these tasks are being started when they are disabled?

How are you disabling them? Just an FYI that Killer Intelligence Center will restart after every reboot if you don't go into Task Scheduler and either disable or remove it from Task Scheduler. Also if you uninstall the whole app you will need to remove it from task Scheduler or it will try to load an app no longer installed and give you an error message.

If you check the first page (as instructed ) - that was already mentioned there:

WHQL version: 40.25.1125.1924
Release Date: January 06, 2026

You can't expect anyone be to be glued to every major manufacture's driver link and report each driver shortly after being released. Intel in particular - adds rather insignificant changes to NW drivers like above (sparking very little interest). It's not like GPU Drivers.

I know that but since it was posted 3 days ago, I thought that the same version was re-released.
