There are endless things you can do with WinPE, but first you must learn to hold it in stillness.
What you will need:
1. Download
WAIK from Microsoft and install it on your computer
2. USB Drive (should be at least 512MB)
3. Computer with Windows 7
First, let's create the WinPE files.
1. Go to Start > All Programs > Microsoft Windows AIK - then right click on "Deployment Tools Command Prompt" and select "Run as administrator".
2. At the command line type the following: "copype x86 c:\winpex86" without the quotes of course. This will copy the WinPE files to the location c:\winpex86. If you need to create a 64bit WinPE boot image, then type the following: "copype amd64 c:\winpex64".
3. Now copy the following file: C:\winpex86\winpe.wim to the following folder C:\winpex86\ISO\sources. After you copy the file in that folder, rename "winpe.wim" to "boot.wim".
