Hi and welcome to new crackme!
1. Your primary objective is to create generic keygen. It should be very easy. And no junk code this time.
2. Secondary goal is to describe anti-stuff. It is also easy and nothing new, so that won't be problem too.
3. And for the end, write solution to help others who don't have such skills as you :)

Victim: MSN Messenger Goal: Patching it so we can run multiple sessions at once instead of just one. Tools: A Debugger (I use Ollydbg) Author: Devoney
When you already have a MSN running you can not launch another MSN at the same time of the same version. When creating your own program you have to build in some security if you want people to be able to run only one session at the same time. So MSN has a moment where it checks if there is a previous version running. We need to find out where that is!

PESpin 1.304 public - repairing IAT
This version of PESpin is completly indentical as previous 1.3. There are no new things in this public version interesting for unpacking, because this version is out just for compability issues. But in previous tutorials there was no explanation for proper IAT fixing , just some tricks to run dump on user machine, so that part will be covered in this tutorial better.

Fishing and keygenning games CD keys
Maybe the best protection today are game protections. Although such protections are very hard to unwrap, it's interesting how their key checks stay very simple in most cases. Indeed, they are simple but the hardest problem is to actually find where the keygen algo lies in application. This tutorial will show a couple of examples on how game CD keys can be fished or keygened more or less with ease in some cases.
