This projects collects my notes while studying the Windows internals. It is divided as follows:

  • Sources:
    • SkeletonDriver : empty driver
    • DispatchPassThru : major function dispatch routine example
    • DispatchIoctl : IOCTL dispatch routine example
    • FSFilterDriver: : Legacy file system filter driver using Fast I/O.
  • Books:
    • Windows NT Device Driver Development by Peter G. Viscarola and W. Anthony Mason (resumed version)
    • Windows Internals 6th edition by Mark E. Russinovich, David A. Solomon and Alex Ionescu (resumed version)
