KernelBase.dll

Windows NT BASE API Client DLL
In order to «improve internal engineering efficiencies and improve foundations for future work», Microsoft has relocated some functionality that was previously found in kernel32.dll and advapi.dll to a «low level binary»: KernelBase.dll.
These two DLLs now forward calls down to KernelBase.dll rather than handling them directly. This forwarding can be static (the export table shows the redirction) or dynamic at runtime (the DLL has a stub to call the function in KernelBase.dll]).
More information is on MSDN: New Low-Level Binaries
