Process Monitor 是一款系統進程監控軟體，總體來說，Process Monitor相當於Filemon+Regmon，其中的Filemon專門用來監視系統 中的任何文件操作過程，而Regmon用來監視註冊表的讀寫操作過程。有了Process Monitor，使用者就可以對系統中的任何文件和 註冊表操作同時進行監視和記錄，通過註冊表和文件讀寫的變化， 對於幫助診斷系統故障或是發現惡意軟件、病毒或木馬來說，非常 有用。

Additional features includes live changes (autoscroll), non-destructive filtering, comprehensive event properties such session IDs and user names, reliable process information, full thread stacks with integrated symbol support for each operation, file logging etc.
