Windows 10: svchost.exe Service Host: Network Service using all my net connection!

I have posted this before for windows 10 to no avail and now with my windows 11 PC it is just the same. This thing runs for hours at a time making anything like YouTube unusable for for the duration, it adds latency to any online game and generally means you have to just sit and wait for it to finish. No process should take over your machine like this without any way to constrain it. I have tried all the suggestions in previous comments, limiting download speed, metered connection etc, nothing stops it. You end task it just pops up again.It is without doubt the worst part of windows and ruins

svchost Service Host: Local Service (No Network) - CPU (10-15%) usage

Hi,
Here is my analysis of the trace file;svchost.exe (2992) process is using 12 % of the CPU. The process call stack shows functions calls from BFE.DLL module !





BFE stand for Base Filtering Engine Service. it's a service that controls the operation of the Windows Filtering Platform (WFP). WFP is a network traffic processing platform that allows software to “hook” into Windows networking stack and perform such functions as firewall, traffic shaping, filtering, etc.

The svchost is doing this job for another process who called it. for that I'll use the CPU precise graph to see which process redied the most our svchost process. this process is probably at the origine of this CPU activity !





You can see that the vsserv.exe process (Bitdefender) makes the svchost process ready to run 2789 times.

To be sure it's Bitdefender the culprit, do the following;
1. disable the Bitdefender firewall and see if the cpu activity decrease;
2. If not; disable all bitdefender application and see if it helps;

If you confirme it's Bitdefender, then you can update to a newer version. Otherwise, unistall it and re-install it again ...

Windows 10 "Service Host: Local Service (No Network)" drains CPU constantly

I've had this problem for at least several months.
I noticed a lot of threads without a happy ending:

1. High CPU Usage from "Service Host: Local Service [...]
   
2. Service Host: Local Service (No Network) (3) and Service Host: Internet Connection Sharing (ICS) causing High CPU
   
3. svchost.exe Service Host: Local Service (No Network) - Permanent CPU usage
   
4. service host: Local Service (No Network) (5) taking up all my CPU resources (i5-4690k)
   

And I did try all the suggestions made in these threads including:

1. Updating the windows to the latest version
   
2. Troubleshoot network, update, etc
   
3. killing all other software, changing MSISUPPORTED of my SSD disk in regedit etc.
   

One thing I noticed is that the problem disappears in safemode.
