The problem is, there *is* an entry point CreateProcessAsUserW in the
Win32 DLL kernel32.dll.
At least on NT-based systems. What strikes me as weird is that
kernel32.dll usually is stored with its name in all lowercase letters on
NT-based systems. The fact that you see an all uppercase KERNEL32.DLL
looks like you have such a DLL in your path, possible from Windows
95/98/Me, possibly installed by some third party stuff, at some point
which is found earlier in the DLL search path than the lowercase
kernel32.dll in C:\Windows\System32.
