後來找到有人用 Windows SDK 中的 Windows Performance Toolkit 來分析 deferred procedure calls and interrupt activity (DPCs and ISRs).


Windows SDK WDK 中有很多好東西及工具
如 WPT ( Windows Performance Toolkit)
App Verifier
Debugging Tools for Windows (dbghelp.dll dbgengine.dll )
PREfast


還有
Network Monitor 3.4
Process Explorer
