Sometimes ntoskrnl.exe and other errors system errors EXE may be related to issues in the Windows registry. Several programs can use the ntoskrnl.exe file, but when those programs are uninstalled or modified, sometimes "orphaned" (incorrect) EXE registry entries are left behind.
Basically, this means that while the actual path of the file may have changed, its incorrect former location is still recorded in the Windows Registry. When Windows tries to look up these incorrect file references (file locations on your PC), ntoskrnl.exe errors can occur. Additionally, a malware infection may have corrupted registry entries associated with the Microsoft Monthly Security Update. Thus, these corrupt EXE registry entries need to be fixed to fix the problem at the root.
Manually editing the Windows registry to remove invalid ntoskrnl.exe keys is not recommended unless you are PC service professional. Mistakes made when editing the registry can render your PC inoperable and cause irreparable damage to your operating system.

The best part is that eliminating registry errors can dramatically improve system speed and performance.

Using Registry Editor incorrectly can cause serious problems and require Windows reinstallation. We do not guarantee that problems resulting from incorrect use of Registry Editor can be corrected. You use Registry Editor at your own risk.
Before manually restoring Windows registry, you need to create a backup by exporting a portion of the registry associated with ntoskrnl.exe (for example, Microsoft Monthly Security Update):
