What's the best disassembly tool on win32 platform? [closed]

Question

I have a win32 software in which I want to do some modifications.

However, I don't have the source code, so I need to do disassembly first.

Could anyone recommend a good disassembly tool on win32 for me?

Answer 1

I've always used OllyDebug and, though my need for this sort of tool is not massive, it's never let me down.

Answer 2

I'm biased, but for disassembly there's nothing better than IDA, in my opinion. You can try the demo or freeware version and see for yourself.
