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)
