The Windows Post-Install setup wizard (WPI for short) is a hypertext application designed to install user-defined programs.
Although Windows XP offers many pre-configured ways to set up the installation process, its main drawback is that it is impossible to select which applications the user can install.
Users and administrators used to have to download installation files manually or create scripts that were too complex and could only be used once.
WPI allows you to solve the problem of installing programs. And now users just need to select any program that is configured in the WPI, and then it will be quickly installed.
