W32DASM

Assembly language (asm) is a low-level programming language that is still taught in some schools to show students how computers make the connection between the language and the machine code instructions of the architecture.

W32DASM is a disassembler: a tool made to translate machine language back into assembly language. It's ideal for those interested in reverse engineering, who want to take code apart and find out how it works.

With this app, you can open .exe, .386, .com, .cpl, .dll, .drv, .fon, .mpd, .ocx, .vbx and .vxd files to study their code. It makes it possible to save the disassembly text and create a project files, attach the active 32-bit process to the debugger, and load the 32-bit disassembled executable file into the process.

You can use a text search function, set the disassembly listing at the current instruction pointer, as well as enable break on load and unload DLL, thread creation and exit. Jumps and calls can be easily executed. What's more, you can search alphabetical lists of functions imported and exported to the disassembly, search the disassembly for string data, or directly examine data objects and segments via hexadecimal display.

As far as customization features are concerned, you can configure font setting. Keyboard shortcuts are supported for all important commands but they cannot be changed into anything else.

Although W32DASM is ancient since hasn't received updates for a very long time (it's officially discontinued), it works without any trouble on Windows 10. Files are disassembled quickly while the tool remains light on system resources consumption.

All aspects considered, W32DASM is great for users interested in reverse engineering, allowing them to take files apart and find out what makes them tick. It''s wrapped in a simple interface and comes packed with practical options.
