Bootable Windows CD/DVD

I'm sure some of you have heard of Knoppix, the software that allows you to run Linux without installing it in your hard disk but runs thru' your CD/DVD drive. Now, you can have the same function with BartPE:

Bart's PE Builder helps you build a "BartPE" (Bart Preinstalled Environment) bootable Windows CD-Rom or DVD from the original Windows XP or Windows Server 2003 installation/setup CD, very suitable for PC maintenance tasks. It will give you a complete Win32 environment with network support, a graphical user interface (800x600) and FAT/NTFS/CDFS filesystem support. Very handy for burn-in testing systems with no OS, rescuing files to a network share, virus scan and so on. This will replace any Dos bootdisk in no time!

This is very useful when your computer kena a virus or something.
