Windows 10: High Ntoskrnl CPU and Battery Usage Probably linked to Intel Display Driver

The bug shows on driver versions 31.xx more than on the newer ones 32.xx , and on both versions it never shows if the Intel Graphics Command Center App is running and the screen is On and immediatly shows back if said app is closed by quitting fron the tray icon, noting that on 32.xx driver vesions it doesnt show even if the screen is off as long as the intel app is running, contrary to version 31.xxI have an Acer Nitro 5 Laptop with an Intel i5-12450 and an Nvidia RTX 4060

high cpu usage of ntoskrnl.exe HvilsHypervisor

Hi Sangmin. I'm Greg, 10 years awarded Windows MVP, here to help you.

1) Try these fixes for known issue of high CPU usage due to ntoskrnl.exe:

2) Go over Windows using this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account to replace yours which may be corrupted. Then if necessary continue with the other steps to go over your install most thoroughly.

3) Update your drivers and BIOS/UEFI firmware from the PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start button. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page. Everything else depends on this.

4) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, is the most stable method to advance to the latest version, and solves most problems.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

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.
