Welcome to the OSR Developer Community!

Have you just discovered our community?
If so, welcome! You can read more about the community here including its history.

In short, this is the place to ask and answer questions about Windows system software development, the Windows Driver Kit (WDK), and Windows kernel-mode debugging (WinDbg). The forums here provide worldwide peer help with solving problems related to the design, development, and debugging of Windows drivers of all types (including WDF both KMDF, UMDF, even WDM device drivers and software-only drivers), Windows file system Minifilters, and Windows file systems. Are you having trouble figuring out how to do something in a driver you're developing? Do you have a crash in your driver that you're having trouble diagnosing? We have a forum for you!
