Invoke Blue Screen of Death using Managed Code

Question

Just curious here: is it possible to invoke a Windows Blue Screen of Death using .net managed code under Windows XP/Vista? And if it is possible, what could the example code

Answer 1

It's possible for managed code to cause a bugcheck when it has access to faulty kernel drivers. However, it would be the kernel driver that directly causes the BSOD (for example, uffe's DirectShow BSODs, Terence Lewis's socket BSODs, or BSODs seen when using BitTorrent with certain network adapters).

Direct user-mode access to privileged low-level resources may cause a bugcheck (for example, scribbling on Device\PhysicalMemory, if it doesn't corrupt your hard disk first; Vista doesn't allow user-mode access to physical memory).

If you just want a dump file, Mendelt's suggestion of using WinDbg is a much better idea than exploiting a bug in a kernel driver. Unfortunately, the .dump command is not supported for local kernel debugging, so you would need a second PC connected over serial or 1394, or a VM connected over a virtual serial port. LiveKd may be a single-PC option, if you don't need the state of the memory dump to be completely self-consistent.
