Not sure if this will help the situation with others, but just to share the observation.
    How did you terminate ICS?? For me it's impossible from Task manager, when I press End task button it offers only to shut down the computer. And in Services it says ICS service is "starting", but Stop button is grayed out.

    How exactly did you disable and enable the firewall?
    I tried turning off the firewall in Windows Defender Firewall from desktop Control Panel, and turning it back on, but nothing changed.
    In Services I can't even disable Windows Defender Firewall service, all buttons are grayed out.

    Same boat here.

    I realised that i have to uninstall Hyper-V to be able to disable ICS completely.

    I don't even have Hyper-V installed and I can't disable ICS.

    In my case, press End Task on ICS gives me a typical confirmation of closing a windows service. I ticked the box and press Shut Down to terminate the process (an example below). I'm not sure whether it's the same in your case.

    I didn't check the status in Services. Also I don't have Hyper-V installed.

    You are right, service is manual startup after reboot as before hyper-v removal but doesn't auto start.

    Confirm you don't have checked internet sharing into any network connection.

    I tried to end ICS task from task manager (check the Abandon box and press shut down), and the CPU goes back to normal for a few minutes, and then comes back with an empty line. Ridiculous! And even more, the System process shows 4-5% CPU usage.

    @Macrom - No, Internet connection sharing isn't checked in Network properties. I tried even to disable LAN adapter, so then the ICS option doesn't even show if there is just Wifi adapter. Restarted the computer, but no change at all.

    This Fall update is such a buggy update! I deleted the old files so I can't roll back to Creator's Update because I haven't had any issues with the past updates. I guess you can never be careful enough...

    In the Windows defender security center, you turn off the firewall for each type of network.

    After turning on again (or pressing restore, I don't know which really fixed it or if its relevant at all), a pop up showed that wanted me to allow or block Google chrome (!) - dunno if chrome is related, or the function of the firewall that controls app access to the network/internet had somehow entered in a false state, causing everything to hang.

    Thing is, after clicking allow, everything settled down and various problems that I experienced, vanished (even BSODs during shutdown which caused windows to repoen all of the apps I left running before the shutdown - and I expected them to close after shutting down and not launch again on the next startup).

    @splus:

    The second entry in your figure (the one with a blank name) was the one I terminated when CPU was occupied again after killing the ICS first time. After killing that blank entry a couple times, the issue seems gone. I have no theory on this but just thinking of a blank name might not be right.

    Not sure if this approach will solve yours, but feel free to give it a try. Such an annoying issue, particularly without the option of reverting back (old files were deleted)

    I experienced this high CPU problem as well after the FCU and (temporarily) resolved it by uninstalling Hyper-V. This is not a great solution as I need it for Docker. The problem also isn't universal; on my home system I'm not seeing a performance hit even with Hyper-V installed.

    The Internet Connection Service has a dependency on the Base Filter Engine (you can view these dependencies in the Services application), which, at least on the problem system, is also showing high CPU use. My sense is that ICS is consuming CPU because the BFE is having problems getting going when Hyper-V (other components might cause the same problem, based on comments here) is installed. The BFE is one of the components involved in providing firewall services. It's not strictly the Windows Firewall that is at fault, as I'm using Kaspersky's Firewall on this work system.

    I've logged an issue with Windows Feedback here. Feel free to upvote it if you're experiencing the problem. Hopefully this can be resolved quickly.

    Really uninstall Hyper-V isn't a solution it's a workaround for high cpu usage. I think Hyper-V and most Vpn clients uses ICS to share Network connections with guest and for internal switch and this is because ICS auto starts if they are present
