His screen-shot wasn't the BIOS, just the Config page for Killer Intelligence Center. Pretty sure Killer Intelligence Center come from the Microsoft-App-Store (not those other places you mentioned).  You can just disable all those "features". IIRC when you disable Auto-Bandwidth they still want you to set the max-es, so go ahead and set it to something kinda high. From my notes: Turned off Auto-Bandwidth by setting to Manual with 320 down/up 10 . Seems extreme, but that's what I wrote in my notes. That is pretty much the full bandwidth of my connection (as revealed by www.SpeedTest.Net ) If you have multiple users (or home-theater movie streaming, etc.) this might be more reasonable: down=100/5=up . That is still really fast.
Both Dell and Windows Updates keep trying to install Killer Intelligence Center on my computer. The last time Dell installed Killer Intelligence Center on my computer, it slowed my internet down so much some pages wouldn't even load. My internet package is the smallest available: 25 to 35 MB per second download speeds. I don't have a super fast 100 MB per second download connection and I'm not a gamer. Today, Windows Updates installed Killer Intelligence Center, again, without asking me! My internet was slow again. I've removed it it, but my internet is still too slow. My connection was fine until the update. What's causing the problem now? How do I fix it?
