Download WPI Today



Windows Post-Install Wizard (WPI for short) is a hypertext application designed for giving users choice. While Windows XP offers many ways of customizing the setup process out of the box, its major drawback is the lack of being able to select which applications an end user may install. In the past, end users and administrators needed to either download the files manually, or create overly complex scripts that could only be used once. WPI allows you to create one image, which can then be custom configured, and optionally, automated, so that end users can install any applications.

WPI was designed by Derek McCabe (Whimsy). It was created for end users to have a simplified interface for installing applications, and as a project for Hypertext applications.

Coolsights2000 developed a new branch of the app, calling it version 3.

Derek and several others maintained the original branch for some time. Then bishooman and gresh announced version 2.7. It was the moment when I began using this cool piece of soft, but I needed some more options and features. So I decided to add new functionality and share it with others ...

hasi001 Did a lot of development for WPI in the last of 2004 and the first of 2005. One of the major advancements was that he introduced us to themes for WPI. He truly did a lot for WPI and without him WPI may have died.

Mark "mritter" Ritter Has been quite possibly the greatest developer WPI has ever seen. Beginning with 4.3.5 he came on board and brought some gigantic changes to WPI especially the Options and Config wizards. He has done a tremendous job on WPI and I personally hope he stays with us for a VERY long time. (I would also like to add a sincere apology to Mark because it took me so long to properly credit him for the work he has done and will hopefully continue to do.)

Note from Kelsenellenelvian:

After having completely gone through the code of WPI from version 3.2 on I noticed that there where some minor issues that needed attention. I found a way to improve theme support (Resolution Changer) and made font installation a lot easier to do. I began my official support with version 3.5 that I developed. I feel humbled to have found this piece of software and be allowed to continue its' development. I have no life and plan on being with WPI for a long while. I plan on trying to add translations for as many languages with WPI as there are for Windows XP. Right now I am developing a user friendly, idiot proof manual for WPI.


Originally, WPI was designed to run at 800X600. WPI 3.5 now theoretically supports all possible resolutions. WPI also requires the Windows Scripting host. Windows 2000, XP, 2003 and Vista can run .HTA Files right out of the box by default. WPI now supports custom made user friendly themes for full customization. WPI has been tested and used on all Windows operating systems from 98 onwards just make sure IE is updated.

It's recommended that you have:
  • Internet Explorer 6 (which comes with XP).
  • Knowledge of program installation switches.
  • Time to configure the thing.
  • Some patience.
  • Also if your project is very ambitious you might consider VMWare or Virtual PC (Which is now free) for testing.

WPI now has 2 developers, Kelsenellenelvian and mritter we are at a high point in the development of WPI. We have plans in the working for a fully capable theme editor integrated into WPI also a random theme chooser for WPI that will randomly choose from the themes in WPI. Also soon to be released is a new function of the RVM integrator that will automatically setup and configure WPI for use in combination Windows\WPI disks. Stayed tuned because just when you think WPI can go no further we figure out new tricks and functions for WPI. I have had WPI under my supervision and development for 18 months now and although it seems like a long time I am just getting started. We are also already started on Vista support and will make sure as Window progresses we will keep right along with it. WPI has been fully tested with Internet Explorer 7 and has been found to work just fine with it.

WPI is close to its third year of development and continues to grow and develop. We just released the new site provided to us kindly by WolfX2. A huge new development for WPI is in the works which will provide a much more professional look and feel to WPI and is appearance. YES the theme editor is still being developed but development is going along at a rather slow pace.

The theme editor has died :(! 6.4 was released today and I was contacted by Whimsy a couple of days ago! (Yes everyone he still lives!) He had all the best to say about WPI and a couple of good suggestions. Henceforth the reverting to a Windows based set of themes. His original dream for WPI was it as a "Stealth" application so that the end user might not even recognize the difference when WPI kicks in during or after setup. So I spent quite some time on trying to get the themes as closely as possible to the XP and Server setup screens. You are very welcome to use any of the custom third party themes found by clicking on the "Themes" link on the side of the page.

There has been a huge surge in production lately! Francesco and myselfidem have provided allot of bug fixes and enhancements. WPI has been in service for nearly 9 years now. Thank you for the 100's of thousand users and maybe even millions of them that has made WPI all that it is over the last years.
