ntsd.exe进程详细介绍
ntsd.exe is a process belonging to the Microsoft symbolic debugger that enables you to debug user-mode applications. This program is a non-essential process, but should not be terminated unless suspected to be causing problems.
Windows2000开始而随系统自带的用户态调试工具。通常情况下可用它结束掉除System、SMSS.EXE、CSRSS.EXE以外的所有进程。
