免费的 Windows XP 兼容操作系统
· 阅读需 3 分钟
React是指 "反抗、抗拒" 的意思。这个 ReactOS 操作系统就是为了反抗 Windows 而诞生的。
ReactOS 项目的宗旨就是为所有人提供一款免费的、开源的并且在执行代码级别与 Windows XP 完全兼容的操作系统。这意味着，任何一款运行在 Windows XP 上的软件，不需要任何改动就可以直接运行于 ReactOS。下图就是在 ReactOS 上安装 Visual Studio 2005 时的屏幕截图。
ReactOS 不仅为穷人带来了福音，对于希望深入学习 Windows 操作系统的人更是一个惊喜。由于 Windows 的源代码是保密的，我们很难了解其内幕。而与 Windows XP 完全兼容的 ReactOS 的源代码却是公开的。通过他的代码，我们就可以清晰地了解 Windows 工作原理。
ReactOS 目前的最新版本是0.2.9。它的安装包、VMware镜像、源代码均可从 ReactOS 的主页下载，地址是：http://www.reactos.org
