An executable compressor, PEC compresses Windows modules (EXE, DLL, SCR, etc..) substantially, while leaving them able to be run just as before. At runtime, compressed modules are rapidly decompressed in memory. PEC is a truly modern exe packer.
PEBundle combines an executable and the modules it depends on into a seamless binary that runs just as before. Modules can even be downloaded at runtime from an internet site if they do not already exist on the client machine.
