解决在安装EVC4.0+sp4时提示“virtual PC/Windows CE Emulator会造成windows不稳定,windows使这些驱动程序无法加载”的问题

小弟这段时间准备搞嵌入式开发,结果在配置安装和运行环境的时候就出了不少问题。上面这个问题的解决方法是我从微软网站上直接拷贝下来的，呵呵，特留在这里小记一下。

方法如下： （这个英文我这个菜鸟级别的都看得懂，不要说看不懂！）
You install Microsoft Windows CE 4.x Emulator on a computer that is running Microsoft Windows XP Service Pack 2 (SP2). The computer has Data Execution Prevention (DEP) hardware. You receive the following error message when you restart your computer:
Devices or applications disabled

'Virtual PC/Windows CE Emulator' will cause Windows to become unstable. Windows has prevented these drivers from loading.
You may also receive the following error message when you try to start Windows CE 4.x Emulator:
Emulator for Windows CE

One or more files from the Emulator for Windows CE installation is missing. Please reinstall Emulator for Windows CE and try again.

To resolve this problem and to run Window CE 4.x Emulator, disable hardware-based DEP on your computer that is running Windows XP SP2. To do this, follow these steps:

1.	Click Start, click Run, type sysdm.cpl, and then click OK.
2.	In the System Properties dialog box, click the Advanced tab.
3.	Under Start and Recovery, click Settings.
4.	In the Startup and Recovery dialog box, click Edit.
5.	Disable PAE mode by removing the /pae option if it exists.
6.	Remove the /noexecute option if it exists.
7.	Add the /execute option.
8.	On the File menu, click Save.
9.	To exit Notepad, click Exit on the File menu.
10.	To close System Properties, click OK two times.
11.	Restart your computer.

通过更改后，一切搞定。
