How to modify the external program directory under PE system

There are a number of Windows7 system users will install many PE systems, as a tool tray to use. The use of U disk to install PE system is very simple, we can say the use of tools Easyboot, UltraISO, Winhex and so on. However, since Xppe and 2003PE are simultaneously on a CD-ROM, so using the same external program is unlikely, how can we modify the external directory after installing multiple PE systems?

1, if you need to extract the external program to replace the external program 360, you must first copy it to the D:boot;

2, then everyone winpe360.is_ renamed as Winpe360.cab (or. RAR);

3, second, we use the WinRAR application to open a Winpe.iso file;

4, followed by the UltraISO open, and extract wxpesystem32pecmd.ini;

5, the use of Notepad to open the way, everyone inside all the external programs directly replace the external program for 360;

6, click Save after we replace it to the Winpe.iso file;

7, then everyone then compress this winpe.iso into a winpe360.is_ copy and replace it with a d:boot;

8, we have the external program 360 directory of the contents of the Winpe.ini file to modify, and finally we have all the external program directly replace the external program 360 on it.
