DriverSpyNT

DriverSpyNT is a one of a kind utility to intercept and monitor NT device driver I/O request packets (IRP). It can hook any virtually any device on the system and show you what processes are interacting with it, and dump the contents of the I/O request packets for analysis. It supports all Windows NT kernels, tested through Windows XP (it should work fine in Vista too).

DriverSpyNT is shareware and, if you wish to continue use, must be purchased after the trial period has ended. Please support this product if you wish to see development on it continue. We allocate our time based on product sales.
