Free executable software for windows

Launch4j is a cross-platform tool for wrapping Java applications distributed as jars in lightweight Windows native executables.
The executable can be configured to search for a certain JRE version or use a bundled one, and its possible to set runtime options, like the initial/max heap size.
The wrapper also offers better user experience through an application icon, a native pre-JRE splash screen, a custom process name, and a Java download page in case the appropriate JRE cannot be found.
Main features:
- Launch4j wraps jars in Windows native executables and allows to run them like a regular Windows program. Its possible to wrap applications on Windows, Linux, Mac OS X and Solaris!
- Also creates launchers for jars and class files without wrapping.
- Supports executable jars and dynamic classpath resolution using environment variables and wildcards.
- Doesnt extract the jar from the executable.
- Custom application icon with multiple resolutions and color depths.
- Native pre-JRE splash screen in BMP format shown until the Java application starts.
- Process name as the executable filename to easily identify your application.
- Works with a bundled JRE or searches for newest JRE / SDK in given range.

A simple program that will log in to your Hotmail account and check to see how many new messages you have, and optionally who they are from. After it is done, it will log you out of your account for you. This installation includes only the executable file, and may not run properly without having first installed it.

exeJ is a free and useful command line tool which creates a "batch-like" executable (.exe file) for your java application. The command line used to start your java application is wrapped in the generated executable and the user can simply start the java application with a double-click.
