Service Host : Network Service running at 25% CPU- fan running constantly

[Bladerunner925]

Last 2 days I have noticed the fan running constantly (and quite loudly)...  looking at Task Manager processes it shows that a listing for Service Host : Network Service is running at 25% CPU- which I am guessing is causing the fan to run.  How do I fix this??

@Bladerunner925 Welcome to HP Community!

Here are a few things that should help resolve the issue:

Solution 1: Disable the Superfetch service

1. Press Windows Logo key + R to open a Run
2. Type services.msc into the Run dialog and press Enter.
3. Scroll down the list of services on your computer and locate the service named Superfetch.
4. Double-click on Superfetch to edit its settings.
5. Click on Stop to stop the service.
6. Set the Startup type for Superfetch to Disabled.
7. Click on Apply and then on OK.

Solution 2: Fix the memory leak in the non-paged pool of memory

If Solution 1 doesn’t work, don’t fret as you can still move onto this solution. To try and resolve this issue using this solution, you need to:

Press Windows Logo key + R to open a Run

Type regedit into the Run dialog and press Enter.

In the left pane of the Registry Editor, navigate to the following directory:

HKEY_LOCAL_MACHINE > SYSTEM > ControlSet001

Click on Services in the left pane and then scroll down under services and chose Ndu.

In the right pane, locate and double-click on the registry value titled Start to modify it.

Change its Value data to 4. Doing so will disable it and plug the memory leak in the non-paged pool.

Click on OK.

Close the Registry Editor.

Restart your computer. When your computer boots up, you should see that System Host: Local System (Network Restricted) is no longer using a massive amount of your CPU and/or Disk.

I attempted both of these steps, and the problem has not gone away. (#1 - there was no superfetch; #2 - no effect). Any further guidance you can provide would be appreciated.

This sounds like a hardware related issue with the system fan,

I am going to say this doesn't seem like a hardware issue to me. I had the same issue in the same time frame. The issue is in software. The symptoms of the issue are that the fan is spinning loudly, and the CPU is running hot. The root issue looks more like "Service Host: Network Service" is doing something that is using 25% (at least its 25% for me) of my CPU all the time. A week or 2 ago, I didn't have this issue.

Now I was tired of this, I had searched everywhere online, and couldn't find an solution that satisfied the issue. So I figured, I will just end the task. Windows warned me that this may make Windows unstable, but I figured that if worst comes to worst, Windows will crash and I will just have to turn on my computer again. So that is what I did, and I haven't had issues since (I also haven't restarted my machine since I think). This shouldn't have to be a solution, and I warn everyone to do this at your own risk. I do not take responsibility for your machine. I only take responsibility for my own machine.

I will eagerly await a more official answer to this.
