Hi,
ntoskrnl.exe is not the real culprit, something else is forcing the issue. If it stopped when you did a clean boot they something disabled was likely the root cause. So perform a Clean Boot again and if it stops enable only 1/2 the processes to see if it still
remains clear. If so disable those and re-enable the other 1/2. When it shows up again diable 1/2 or that 1/2. Use that process of elimination until you find the cause. Keep in mind that such an issue could be the interaction of two or more of them.
If using an SSD or hybrid hard drive be sure it has the latest firmware.
Try the Clean Boot method to see if a startup program is involved - if so it is a
process of elimination :
Right Click the start button - Command Prompt (Admin) - at the prompt type in
MSCONFIG
and hit enter

==================================================
More if needed - do all of these :
If you had a 3rd party antivirus on the OS you upgraded OR if you have one
now uninstall it and then run its maker's removal tool. Use Windows Defender
which in Windows 8/8.1/10 is a full antivirus. Despite all the hype out there
Windows Defender and the Windows Firewall are true superstars.

Tips to improve PC performance in Windows 10
<-- read this link
https://support.microsoft.com/en-us/help/4002019/windows-10-improve-pc-performance
The below is additional help with some of the methods in the "Tips to improve...." link.
Windows Key + X - Command Prompt (Admin)
SFC /scannow
Note if that shows uncorrected errors - do the below regardless.
When that completes run these :
DISM /online /cleanup-image /scanhealth
DISM /online /cleanup-image /restorehealth
Note if that shows any uncorrected errors - do the below regardless.
Then restart the computer.
Be sure you are running the latest available BIOS and drivers.
Check with System Maker (Motherboard Maker for custom systems) for updates
to the
BIOS,
low level chipset drivers, and the
major on-board and separate
device drivers. Run DriverView - set VIEW to Hide Microsoft drivers - update
those without Dump in their name.
DriverView - Free - utility displays the list of all device drivers currently loaded
on your system. For each driver in the list, additional useful information is
displayed: load address of the driver, description, version, product name,
company that created the driver, and more.
http://www.nirsoft.net/utils/driverview.html
For Drivers check System Maker as fallbacks and Device Maker's which are the
most current. Control Panel - Device Manager - Display Adapter - write down
the make and complete model of your video adapter - double click - Driver's
tab - write down the version info. Now click UPdate Driver (this may not do
anything as MS is far behind certifying drivers) - then Right Click - Uninstall -
REBOOT this will refresh the driver stack.
Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard
if 3rd party with their own software and drivers and any other major device drivers
you have.
Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and
then Device Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their
latest versions. (Look for BIOS, Chipset, and software updates at System Maker's
site while there.)
Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN -
REBOOT after each installation.
Always check in Device Manager - Drivers tab to be sure the version you are
installing actually shows up. This is because some drivers rollback before the
latest is installed (sound drivers particularly do this) so install a driver - reboot
- check to be sure it is installed and repeat as needed.
Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER -
heck manually by model.
Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Hope this helps.
