有一段时间了，但是没有怎么去注意，昨天在调试一手机程序时，出现了不能启动模拟器的问题，所以着手解决了下。
症状：“virtual PC/Windows CE Emulator会造成windows不稳定,windows使这些驱动程序无法加载” 、 EVC “One or more files from the Emulator for Windows CE installation is missing. Please reinstall Emulator for Windows CE and try again.”
解决方法：MS的官方说了一大堆，其实就一句话：修改boot.ini文件。在浏览器或者是命令行运行“file:///C:/boot.ini”，修改里面的启动参数，如果有/page的，去掉，有/noexecute的改成/execute就ok了，重启。。
起因：当hardware-based DEP (基于硬件的数据执行保护)启用时，Windows XP SP2（SP3应该也是） 的驱动保护机制不允许加载Virtual PC/Windows CE Emulator driver (VPCAppSv.sys)。
如果愿意去看官方的，这里围观（E文的）：http://support.microsoft.com/default.aspx?scid=kb;en-us;891667
PS:史上最长的国庆假期来了（又老一岁！！！），还是决定回老家看看，因为有可能过年有可能不在家过了。。。
