OllyDbgOverview

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
Debugs multithread applications
Attaches to running programs
Configurable disassembler, supports both MASM and IDEAL formats
MMX, 3DNow! and SSE data types and instructions, including Athlon extensions
Full UNICODE support
Dynamically recognizes ASCII and UNICODE strings - also in Delphi format!
Recognizes complex code constructs, like call to jump to procedure
Decodes calls to more than 1900 standard API and 400 C functions
Gives context-sensitive help on API functions from external help file
Sets conditional, logging, memory and hardware breakpoints
Traces program execution, logs arguments of known functions
Shows fixups

NEW:
The second beta. I've planned that it will come with the more or less complete help file. Unfortunately, I had no time to write it. Therefore there will be also the third beta release... soon.
There are many - over 20 - bugfixes in the beta 2, some of them are really critical. As promised, there are no significant changes, with two exceptions. The recognition of UNICODE strings is vastly improved, they are no longer limited to ASCII subset .

New

Fixed some bugs.
