Looks like you already discovered the way to do it, unless you want to dive into native libraries etc.

FileSystemView uses Win32ShellFolder internally so they are basically the same.

I also dug up the Source for org.eclipse.swt.program.Program and with it org.eclipse.swt.internal.win32.OS. The OS class then uses a native call for the Icon. At this point unless you really really cannot create a Temp File i would not go down that path.

For JDIC i only found http://kickjava.com/src/org/jdesktop/jdic/tray/internal/impl/WinTrayIconService.java.htm with a little bit of digging(may not be related but does icony things :D). Also calls native.
