OllyDbg is a 32-bit assembler level analysing debugger for Microsoft® Windows®. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable. OllyDbg is a shareware, but you can download and use it for free. Special highlights are:

    * Intuitive user interface, no cryptical commands
    * Code analysis - traces registers, recognizes procedures, loops, API calls, switches, tables, constants and strings
    * Directly loads and debugs DLLs
    * Object file scanning - locates routines from object files and libraries
    * Allows for user-defined labels, comments and function descriptions
    * Understands debugging information in Borland® format
    * Saves patches between sessions, writes them back to executable file and updates fixups
    * Open architecture - many third-party plugins are available
    * No installation - no trash in registry or system directories
