XP live usb edition

I downloaded the windows xp live (usb edition) but I know how to do it
is written rename usb key in HPUSBFW.exe, format the key fat, copy all the files in the key, in fact I have not understood I would like a clearer explanation.

Although convenient this version is beyond the scope of copyright and is based on an illegal version of Windows XP therefore we can help you with this topic because of the legislation. However you can do the same thing by using BartPE and a version of Windows that you have the license.

This is what you need :
-USB stick with 256 MB capacity. 512 MB Recommended.
-A system that supports booting from Usb stick.
Installation :
1. Rename USB stick through file HPUSBFW.exe and format with FAT file system.
2. Copy all the files from a folder on USB stick.
Start :
1. Reboot the computer.
2. In BIOS or through Quick-boot menu choose boot from the USB.
