CExe download | source code
CExe is a Win32 based .exe compressor. It has a framework for multiple compressors and tries them all, choosing the compressor that results in the smallest size. It even compresses the choosen decompressor code with a secondary compressor. Currently the framework has compressors for lzw and zlib. zlib usually wins; however if the file is small lzw can be better since the lzw decompressor is small.
Here are some results:
