file  

Ntoskrnl is the core of Windows and provides key system services such as hardware virtualization, process and memory management. . Ntoskrnl contains the Cache Manager, the Executive, the Kernel, the Security Reference Monitor, the Memory Manager, and the Scheduler, along with other components.

  • NTOSKRNL.EXE, single-processor without PAE
  • NTKRNLMP.EXE, multi-processor without PAE
  • NTKRNLPA.EXE, single-processor with PAE (XP and later)
  • NTKRPAMP.EXE, multi-processor with PAE (XP and later)

The WinSxS directory holds Windows Side-by-Side DLLs. WinSxS allows multiple versions of the same DLL (code libraries) to exist on the same system. This ensures that every application will get the DLL version they were tested and designed for. The result is improved application and system stability.
