微軟家的執行程序和診斷工具Debug Diagnostic Tool(DebugDiag)，可用來排除:當機(hangs)、效能變差(slow performance)、記憶體洩漏/碎片(memory leaks/fragmentation)、和任一使用者模式的執行序崩潰現象(crashes in any user-mode process).

官網原文如下

The Debug Diagnostic Tool (DebugDiag) is designed to assist in troubleshooting issues such as hangs, slow performance, memory leaks or memory fragmentation, and crashes in any user-mode process.

**使用上大同小異，對我來說，能解決問題的都是好工具XDDD
