This hands-on training course imparts the knowledge and practice necessary to begin writing WDM device drivers for Windows XP, Windows 2000. All these features are included in this course, and importantly these are covered step by step to make your experience of learning device driver programming less daunting. This model is complex and contains many components like Plug and Play (PnP), Power management, Windows Management Instrumentation (WMI), etc. Today almost all device drivers for Windows platform follow the Windows Driver Model (WDM). In addition it is necessary to learn the device driver development environment and kernel mode debugging.
