My PC :


Windows 10 Family

Intel Core i5-7300HQ

16 Go RAM

Fix ntoskrnl high cpu usage for Windows 10 Pro?

In mid - late December 2019 I noticed a lag in starting applications after booting (or powering up) my Windows 10 desktop. Outlook, Word, Excel, and others has a noticeable delay in starting. Once I noticed this behavior I started task manager and noticed
a process named 'System' running consistently at a CPU rate of 15 - 17%. No matter how long the system was running, even with no active applications started or idle, the CPU rate never changed for this 'System' process. I've watched task manager before and
have never had a process 'System' running at this rate. Normally when present this 'System' process runs at around 0.2 - 0.4% CPU.

I selected 'System' looked at properties and it is the 'ntoskrnl' process. Next, I went to Micorosoft technet and forums looking for information related to this issue. And, of course, I found a plethora of questions, discussions, etc., all involving ntoskrnl
and high cpu utilization, some dating back to 2016. I followed the ones posting in 2019 and tried all the suggestions for fixing this issue. Uninstall this, remove that, kill items in startup, perform a clean boot, check registry and change this, etc., etc.,
etc..

Non of these worked. I returned the system to the current configuration I've been running for 3 years. Here is what I noticed: If I rebooted (selected 'Restart'), the system rebooted and the 'System' process aka 'ntoskrnl' process was running at 0.2 - 0.4
CPU rate, after about 20 -30 seconds. If I 'shut down' the system to a power off state and then start the system up there is always the 'ntoskrnl' running at the high CPU rate - forever. Perform a reboot (even an immediate reboot) then 'ntoskrnl' is running
at the normal 0.2 - 0.4% CPU rate. And there is no lag in starting Outlook or Word or Excel, or etc. The system is back to running normal performance only after a reboot.

So why is ntoskrnl having the aberrant behavior? Please help by looking into this. This issue with ntoskrnl keeps resurfacing and Microsoft has not fixed this.

Here is my system information- Windows 10 Pro 64 bit, 16GB RAM, Intel i7-6700T CPU, 512GB SSD, all updates current as of Jan 3 2020

Two suspicious updates:

1) December 10, 2019-KB4533002 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903 and Windows Server 1903 RTM and Windows 10, version 1909 and Windows Server, version 1909

2) December 10, 2019—KB4530684 (OS Builds 18362.535 and 18363.535)

The ntoskrnl properties lists the following: Created Wednesday Dec 11, 2019, Location C:\Windows\System32 - this incredibly suspicious because this is the same time frame that I noticed the system behaving differently. AND it certainly suggests that one
of these updates has corrupted the WIndows 10 Pro performance in the ntoskrnl service.

 

System (ntoskrnl) high cpu usage

On startup the ntoskrnl process quickly begins using 30% of my cpu power without any other tasks running

this wont go away although performing a restart seems to cure it, whenever I turn the pc on from cold it starts again

I have done a fresh install of windows 10, gone through every device in device manager and updated the drivers, done every scan mentioned on this issue on other posts but the problem still persists

any advice on how to solve this problem completely?

Hi,

To help you with your concern, we suggest you to try running a Windows System File Checker with the following steps:

• Click Start.
• Type command in the search box.
• Press Control + Shift + Enter
  button on your keyboard.
• Enter your credentials on the permission dialog box, then click Yes.
• A black box will open with a blinking cursor.
• Enter sfc /scannow.
• Wait for the System File Checker to scan for msvcp_win.dll. System scan may take a while.
• Follow the on-screen commands.

We also suggest a clean boot in Windows. You can refer to this
link for steps.

Let us know how it goes.

Thank you.
