32位操作系统下：最简单的安装64位windows7系统
第一步：先把32位win7的iso系统文件和64位win7的iso系统文件分别加载到虚拟光驱（假设为G盘和H盘）。
第二步：以管理员身份运行cmd， 手工输入如下命令：G:setup/installfrom:H:sources\install.wim。 
(/installfrom”参数指向64位的install.wim，这里的“G:\setup”代表32位Windows 7，而“H:\sources\install.wim)则表示来自64位Windows 7的安装镜像（具体盘符根据个人电脑不同可能有差别，大家自行修改吧）。
执行上述命令之后，立即就可以在32位系统上正常运行64位Windows 7的安装程序，是不是很简单？
第三步：按照常见的安装32位windows7方法接着操作就行了。
