PECompact (Student version) by Bitsum Technologies

PECompact 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. Smaller (<50%) size usually means quicker load time. Compression also adds a layer of security to modules that resists tampering and reverse engineering. PECompact supports multiple compression formats, including LZMA, through the use of CODEC plug-ins.
