WinPE Prestart and Startup

I just discovered that you can customize WinPE using the prestart and startup folders.

Here are some things to keep in mind when using the folders:

1. All batch files you add to the prestart folder are run just before the network loads.
2. All batch files you add to the startup folder are run just after the network loads.
3. The batch files are run in alphabetical order.
4. If your batch file launches another batch file, be sure to use the call command, or it will not return to the WinPE startup batch.
5. If your batch file launches a program that will stay running be sure to use the start command, or it will hang and the WinPE boot will not continue.
