CPU Usage of the Process "System" always between 20 and 25% total CPU usage

[Dagru]

Dear Community, I have a Problem, I can't solve for months.
As described in the title, my Elitebook has always between 20 and 25% CPU usage, from the System Process, which contains the "svhost" subprocesses.
I never had this problem before, my tower PC has nearly 0% System CPU Usage, the Elitebook I had before had this problem neither. 
Now some technical facts: 
- CPU: i5-8250U
- Windows has no new updates, nor any application updates, both is ensured right now.
- Windows is completely fresh, I set it up yesterday, and left it time until today, to set everything up and install and do his windows stuff.

So I don't have any idea left, what I can do, not even setting windows up fresh helps. Maybe there is a problem with elitebooks and Windows? I read, that some other people had the same problem with Elitebooks, but as far as I found out, nobody found a real sollution.

Thank you very much, maybe someone has a fresh idea, or stumbles opon this, having the problem solved themselfs.

Unless you installed lots of apps that load automatically at Windows boot, why would you think a clean install of Windows would make your system run any faster or use less processor resources?  

When you do that, you automatically force Windows Update to then contact MS, search for updates, download and install them, and that ties up the pc for HOURS.  That's not going to reduce the processor demands.

It's not a miracle cure, but I use Black Viper's suggestions on my PCs and that reduces processor load considerably by disabling services I simply don't need.  Here is the link to that:  Black Viper’s Windows 10 Service Configurations » Black Viper www.blackviper.com

First of all, thank you for the reply, it was a little bit off topic, but thank you for trying to help 🙂
Making a fresh install helps for example, if you have flaws in the system, caused by flawed updates, that windows can't resolve themself, and sometime get dragged along until the next update fixes them, or for ever. These flaws cause the system internally to have, lets call it microcrashes. For example, your printerspooler crashes, the OS tries to pull the resources back from this faulty process and to kill it. System Internal, or driver processes are a little more delicate in that matter, because it is a lot harder for the system to detect and kill a flawed system process. This flawed system Process can cause a lot of subprocesses, trying to fix the problem, fix the update, or get the device working, sometimes resulting in a never ending circle of new processes, and killed processes. That is why if your System crashes, it often results in a blue screen and the PC to boot up again, to load all processes fresh, hopefully without a faulty one.
If that does not help, all you can do is reinstall. 

I found the problem. I just had the idea, that it could be the build in AMD graphics card. Since Day one this Graphics card caused nothing but trouble, not working properly, not accepting getting activated as main graphics card and so on. 
Tried new Drivers, tried to install AMD specific programs, no way, activating this card. Finally I gave up on it and simply let it live beside the Intel 620.

Now I deactivated it completely in the system and just in that moment the CPU Usage of System dropped from 20% to 0.3%.
Very likely Windows tried to communicate with the graphics card, causing it's processes to crash, trying to solve the crashes, resulting in a never ending circle of crashes and instantly System pulls enormous CPU resources.

SO if you stumble over this post and you have the same problem, try disabling devices, in your device manager, could be a faulty device/driver. Use your brain doing so tho, not every device is optional for your OS, you could cause yourself some problems. If you want to try this without knowledge, definitely before trying around, make an backup on another Harddrive!
And google it, before you disable it!

@HP, do you know, that there are potential Problems with the AMD 530, or do I have a flawed device?

Yeah, I know what a clean install does in terms of removing problematic stuff -- it's just that ALSO, unless its done from a very recent build of Windows, it also saddles your PC with HOURS of Windows Updates during which your PC is basically unusable.  And then when your done, you have all this Windows Update crud filling up your drive.

Good to see you got it sorted -- at least to some degree.

I would still recommend looking into the Black Viper tuning suggestions.

As to your final comment, we are not HP, we are just a bunch of volunteers, so posting stuff here intended for HP management is not accomplishing anything.

Yeah, that is why you get the freshest ISO directly from the Microsoft website. 
Than you have nearly no problems with updates, give it an hour maybe, to finish the whole installation in the background and to check if everything is up to date and every device has a driver and normally you are instantly good to go, apart from deleting some junk, that gets automatically installed with it.

Why would you want to use an old version, with no security updates, and install all of them manually, after you installed it? That is so unnecessary, you can get the newest version of Windows 10, directly from their website, super easy, they even deliver an installation tool with it, if you want it.

But yeah, we drift further and further from the original topic.

So here in this official HP forum are no HP officials, no Forum Managers, nothing? Well, that is... unusual and a bit terrifying. I really did not expect that from a forum, directly on the official HP Website. Really strange...

Well, then next time I have a problem, I directly write the official support of HP. 

Thank you for your time.

While you can in fact, often get the latest version of Win10 ISO directly from the MS download site, that is NOT always the case.

They have been very irregular about WHEN they post new ISOs to their website.  Sometimes, they are only a few days behind; other times, they have been weeks or months behind.  It depends on when they feel like updating the Media Creation Tool.

If you check the MCT now, it will likely say Win10 bld 19041.450 -- and bld 488 just came out today.  So, it is already behind.

As to writing the Official Support of HP, there is no such address as HP Technical Support provides no email address or texting address.  This forum is where you go to get support.
