Remarks

The .trap command displays the important registers for the specified trap frame.

This command also instructs the kernel debugger to use the specified context record as the register context. After this command is executed, the debugger will have access to the most important registers and the stack trace for this thread. This register context persists until you allow the target to execute or use another register context command (.thread, .cxr, or .trap). See Register Context for full details.

This extension is commonly used when debugging bug check 0xA and 0x7F. For details and an example, see Bug Check 0xA (IRQL_NOT_LESS_OR_EQUAL).
