Ptree.exe: Process TreeNEW

Process Tree allows you to query the process inheritance tree and kill processes on local or remote computers.

By default, local Administrators, Power Users, and Users can query the tree, but only local Administrators and Power Users can kill processes.

The tool consists of a kernel-mode driver (Ptreedrv.sys), a Microsoft® Windows® 2000 service (Ptreesvc.exe and Ptreesvcps.dll), a COM+ server (Ptreesvr.dll), a console client (Ptree.exe), and a GUI client (Ptreeg.exe). Ptreeg.exe allows you to manage the process inheritance tree on multiple computers simultaneously.

Note

You can change the security settings of Process Tree by using Component Services in Administrative Tools at any time, because Process Tree uses COM+ role-based security.
