PsTools 是 Sysinternals 公司推出的一个功能强大的远程管理工具包，一共由12个命令组成，可以用来远程管理 Windows NT/2000/XP 系统。该软件在DOS窗口中操作，虽然没有漂亮的图形界面，但是功能却十分强大，使用起来也很简便。

The Windows NT and Windows 2000 Resource Kits come with a number of command line tools that help you administer your Windows NT/2K systems. Over time, I've grown a collection of similar tools, including some not included in the Resource Kits. What sets these tools apart is that they all allow you to manage remote systems as well as the local one. The first tool in the suite was PsList, a tool that lets you view detailed information about processes, and the suite is continually growing. The "Ps" prefix in PsList relates to the fact that the standard UNIX process listing command-line tool is named "ps", so I've adopted this prefix for all the tools in order to tie them together into a suite of tools named PsTools.
