How do I turn off the Prioritization Engine permanently? It keeps turning itself back on! Thanks!

Never mind - just saw your most recent reply!

Hmm... I thought I had fixed this with the Major Geeks uninstaller but today I noticed the Killer software was back!

With the Major Geeks uninstaller, I use the first two buttons to Scan and Remove the Killer software. Then when I click on the Disable button, I get a message that says "---Disabling Killer Software (Service and KCC)---" and that's all that ever happens. Does that mean it's not finishing that process?

Thanks!

Had similar experience with the software activated again after using the majorgeeks tool. So this was useless.

What I found to work so far was keeping the software installed, and turning the Perioritization Engine off, and also disabling Auto Bandwidth. This will prompt for setting a bandwidth. Set the up and down speeds to something like 1500 MB.

This I found on the Dell website at this link: https: //www.dell.com/support/kbdoc/en-us/000135709/slow-internet-speed-using-killer-ethernet-adapters

I do have XPS 8930 and this did the trick for me . I hope this works for other models or brands.

So far this solution has worked. I have turned the PC on and off for several weeks and the UP and DN speeds are normal at the ISP nominal rates, and those settings at the Killer software have stayed the same.

Cheers.....

Thanks, Mac! Prior to getting your reply, I disabled the three Large Send Offload properties for Killer in Device Manager. That seems to be doing the job for me, but if I have the issue again, I'll definitely give your approach a try!
