Question

There are some nice debugging tools available for windows like

Process Explorer Process Monitor Spy++ ( There is some variant of Spy++ like tool also available but I forgot name.. :( )

All above tools are really handy to debug windows application...

Do you any other such tools(Windows or 3rd party) which can be used to make debugging task more ease ?

Answer 1

IDA Pro

When it comes to track down bugs in third-party components without access to the source code, nothing beats IDA Pro.
