As far as I know, you'll have to write some native code to access platform specific features.
But if you can write a dynamic library (dll) that accesses the Windows registry you can declare a native method in your Java code and access that method after loading the library with the System object.
Hope this helps

This work of writing native code to access the windows registry has of course already been done by various parties.
Microsoft has libraries to do so in the com.ms.wfc package. http://msdn.microsoft.com/visualj/technical/tutorial/wfcregistry/default.asp
However you only get those with J++ and I have no idea if you can legally get them elsewhere and redistribute them or not.
There is a products called JNDI that looks like it can do it:

It also appears that the Java 1.4 preferences API can look into the Windows registry, here is an example:
