windows server 2003 service pack 2 无法安装...产品密钥可能无效

cf2000

　　今天安装vs时提示安装service pack，结果先后下载了sp1\sp2都无法安装
　　提示如下：
　　windows server 2003 service pack 2 无法安装。
　　用来安装Microsoft Windows的产品密钥可能无效。有关接受到此错误消息的原因和如何解决此问题的更多消息，请访问www.howtotell.com.
　　
　　出现此错误原因主要是因为你使用的windows server 2003 是SP1 且是盗版光盘，无法升级到SP2 （还是要支持正版的）。
　　于是在网上找了一些reg的文件，多数为残缺不全的害得我把原来的系统搞的不稳定。
　　现把完整的代码贴出来，希望朋友们不再有和我相同的经历。
　　解决方法及代码：
　　将下面框内内容复制保存为以*.reg为后缀的文件，双击写进注册表里，就OK了！
