How To Fix High RAM and CPU Usage of       Windows 10 System (ntoskrnl.exe) Process?
 Instead of changing any advanced system settings on your PC, make sure that your PC isn’t affected by some malware. Most of the users have upgraded their PCs from older Windows 7 and 8.1, thus any malware in previous OS gets migrated to Windows 10. You can install the anti-malware tools like MalwareBytes to deep scan your Windows 10 PC.
After the scan, reboot your PC. Now, move to the next solution to fix high RAM and CPU usage if this problem stills persists.
On Reddit and Microsoft forums, people have claimed that the root cause of this Windows 10 memory leak is some faulty driver. If you have RAID disk drive setup, update those drivers. Also, try updating the remaining hardware drivers as it’s a problem caused due to unmatching OS and drivers. It is a known fact that Microsoft has decided to take control of the update process. Still, we recommend you to update the network, graphics and sound drivers manually. This step has worked for the most of people.
Some discussion threads suggest that Runtime Broker is one such system process that eats large chunk of CPU power due to the poor memory optimization. This process doesn’t deliver any functionality as such, so you can disable it.
To disable the Runtime Broker, open the Settings app and go to System. Inside System window, locate Notifications & Actions and unselect “Show me tips about Windows.” Now restart the PC to bring it back to the normal and fix high RAM and CPU usage.
