The old stuff

 Email Article To a Friend View Printable Version 

NewsYou might notice some old tutorials from the biw.rult.at site being submitted again on this site.

Though most targets are outdated, and some tools are not used anymore, many people think they still have a great value for learning the 'art of reversing'.
Or they have at least some sentimental value for some of us ;)

You are welcome to re-submit older tutorials if you think they still are of some value.

Thanks to ColdT for submitting this first serie of old tutorials :)

Today's issue is dedicated to changing the startup logo of Windows XP. Well, I suppose anyone who used Windows 2000 (NT 5) or Windows XP (NT 5.1) for a long time might probably fed up with standard Windows logotype during the boot.
You may say, so what there're lots of tools around the net, which can change the logo like 1, 2, 3. Of course, it is so, but those tools can learn you nothing. If you wanna learn something then get your spade & let's start digging-in.
