The Microsoft Web Application Installer—officially and more widely known as the Microsoft Web Platform Installer (Web PI)—is a discontinued free tool that automated the installation of Microsoft’s web technologies and popular open-source web applications.
First released in 2008, it acted as a lightweight software manager. It allowed users to turn a local Windows computer or server into a fully functioning web environment with just a few clicks. However, Microsoft officially retired and shut down the Web Platform Installer on December 31, 2022, pulling its download packages and application feeds offline. 🛠️ What the Tool Did
Before its retirement, Web PI was highly valued by beginner developers and IT administrators because it simplified server management. It targeted three main areas:
Microsoft Core Stack: It detected system specs and installed tools like Internet Information Services (IIS), SQL Server Express, and the .NET Framework.
Dependency Automation: If you wanted to install a specific framework, the tool automatically found, downloaded, and configured all necessary background files and software.
Web Application Gallery: It allowed one-click installations of third-party open-source web applications like WordPress, Drupal, Joomla, and Umbraco directly onto Windows. 💻 How the Installation Process Worked
