High CPU or Disk Usage by Ntoskrnl.exe on Windows 10 [Fixed]

System items are items that run at startup. These include programs such as ntoskrnl, which manages hardware accesses. Some system items hog resources, though, because there are too many processes competing for memory and processor cycles at once. To see what process is hogging all the memory, open Task Manager and select Performance. Under the Memory section, you’ll see a list of processes sorted by how much RAM each one uses. If there are several processes consuming lots of memory, it’s likely that some of those processes are slowing down the computer.

To fix this problem, try disabling unnecessary system items. Open Device Manager and locate the device named “Microsoft Hypervisor Service.” Right-click on it and choose Disable. You might want to restart your PC afterward.
