Well, what if you really want a command prompt so that you can do some troubleshooting (e.g. checking if a network driver has been installed)? Simple, press the F8 key and one will be started for you. (This command prompt should behave like the one in ConfigMgr 2007: as long as you have a command prompt open, the machine won’t reboot. However, there is a problem with that in MDT 2010 Beta 2 so the machine will reboot even with the command prompt open. That should be fixed before the final release of MDT 2010.)
如果你需要一个命令行来排查问题。简单，按下F8，就会自动运行一次CMD，这个命令行和SCCM2007里的命令行类似，一旦运行，那么机器就不会重启，目前Beta2中如果MDT需要重启还是会重启的，这在正式版里会进行修正
In MDT 2008, the Windows PE startup process was something close to this:
在MDT2008中，PE的启动步骤是这样的：
- Windows PE started CMD.EXE to run STARTNET.CMD.PE启动CMD，运行Startnet.cmd
- STARTNET.CMD started WPEINIT.EXE.Startnet.cmd启动了WPEINIT.exe
- WPEINIT.EXE initialized networking and optional components, then ran “WSCRIPT.EXE X:\Deploy\Scripts\LiteTouch.wsf”.WPEINIT.EXE初始化网络和可选组件，然后运行WSCRIPT.EXE X:\Deploy\Scripts\LiteTouch.wsf
- LiteTouch.wsf started a minimized CMD.EXE, for troubleshooting, then runs the Welcome or Deployment Wizard.Litetouch.wsf运行了一个最小化的CMD.exe，用于解决排查问题，接着运行部署向导的欢迎界面
That
meant that there was always a command window visible on the screen, as
well as another minimized one that could be used for troubleshooting.
Some didn’t like that cluttered look, so they hooked in utilities to
hide these command windows.
With MDT 2010, that will no longer be necessary. The startup process has been modified:
在MDT2010里，启动步骤修改为：
- Windows PE starts BDDRUN.EXE.PE运行BDDRUN.exe
- BDDRUN.EXE starts WPEINIT.EXE.BDDRUN.EXE运行WPEINIT.EXE
- WPEINIT.EXE initialized networking and optional components, then ran “WSCRIPT.EXE X:\Deploy\Scripts\LiteTouch.wsf”.WPEINIT.EXE初始化网络和选择的部件，然后运行 WSCRIPT.EXE X:\Deploy\Scripts\LiteTouch.wsf
- LiteTouch.wsf runs the Welcome or Deployment Wizard.Litetouch.wsf运行部署向导的欢迎界面
That means no command windows at all:
