How to use WinDbg?

[Jack]

With windbg, I click on "Open Executable" from the menu and "open" the exe
file, windbg will stop at ntdll!DbgBreakpoint. I'd like to know how to use
windbg? just any normal/simple debugging usages... like starting the program
at the entry point or something like that..
And also how can I switch from VS2005 debugger to windbg? and what are the
benefits of switching to the kernel mode debugger in this case?
Thanks in advance
Jack

The question is why do you need to switch from VS2005
debugger to WinDbg? The benefit of switching to kernel mode
debugger is the ability to debug kernel mode code,
obviously.

If you need quick WinDbg tutorial then just google for
"WinDbg" and "tutorial".
