Free development tools for Windows platform

This might be too late to post this, but anyway...

If you are working on Microsoft Windows platform and wanting a free development tools to develop system, this would be one of the list.

1. Microsoft Visual Studio 2008 Express Edition for IDE
2. Microsoft SQL Server 2008 Express Edition for database engine
3. Microsoft SQL Server 2008 Express Management Studio for database management
4. Paint.NET for image processing (additional plugin for icons)

These are the tools/technology that I have been using to develop applications and I pretty much enjoy it.
