You can use java.util.prefs to read and write to the registry. See this question for some examples.

There's no built-in way to read registry keys, but there are various third-party Windows-only libraries to do this. Of course, you should avoid it if you can -- why not write portable code that doesn't use the registry if you can? There's rarely a need.

Regarding installers, there are a number of products that do this: InstallAnywhere, for example.
