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.
