The XP TCP/IP application is used to reset your TCP/IP and Winsock registry settings to the default values. The application can be installed to Windows XP only if it has no effect on Windows 7. The developer doesn't provide any information related to the ISO booting.
To create a boot disk in Windows 7 for a Windows XP computer, use WinToFlash and a Windows XP Installation disk. Download and install the application, then use the built-in Wizard to help you create a Windows USB boot disk.
Note: The XP TCP/IP's setup file won't give you the possibility to create a boot disk.
