NSIS 是“Nullsoft 脚本安装系统”(Nullsoft s criptable Installation System) 的缩写，它是一个免费的 Win32 安装、卸载系统，采用了简洁高效的脚本方式。它本来是一个由 Nullsoft 创建并用于作为 Winamp 及其插件发布的系统，但现已被上百个应用程序所应用，作为它们进行程序发布的工具。

NSIS 创建的安装程序可以进行安装、卸载、设置系统设置、解压文件等等。几乎可以做所有事情。因为它基于脚本文件，所以你可以完全控制你的安装程序的每个部分。它的脚本语言支持变量、函数、字串处理，就像是一个普通的程序语言 - 但其仅设计用来创建安装程序。

简体中文增强版除了主程序的翻译之外还把主要的文档作了翻译并修正了官方版本里简体中文语言习惯用语不合适之处。
单纯的使用脚本来编写安装程序对于大多数人来说不仅困难而且容易出错，为此，简体中文增强版里集成了一个相当好用的脚本编辑器 - VNISEdit。只需要根据向导就能轻松的做出很酷的安装程序，甚至，你还可以在向导里给你的安装程序添加启动画面、让你的安装程序在安装过程中播放音乐，而这，只需要点几下鼠标即可。除此之外，VNISEdit 附带的注册表转换插件还可以把 .reg 文件一次性的转换为 NSIS 脚本，补丁制作向导可以一次性地为你生成体积超小的补丁升级程序。简体中文增强版还在官方版本的基础上集成了一些有用的插件，比如 FindProc 可以根据可执行文件名查找进程是否在运行，这在制作补丁程序或者是汉化包时非常有用。由于各个组件在使用时各自独立，所以强烈推荐安装全部组件
