 PythonForWindows allows you to create native function callable from Python (thanks `ctypes`) and also embed
 a simple x86/x64 assembler.

-Some code are just explorations and need improvements like:
+To easily script some signature check script, PythonForWindows implements some wrapper functions around ``wintrust.dll``

+# Get WMI data for current process
