WAMP

I recently decided to install XAMPP on Windows. I have done in many times on Linux and process was always very smooth. The installation of XAMPP on Windows Vista turned out to be a task from hell. For a long time I could not start Apache web server. First it would not start because uninstalled IIS kept some junk behind that was blocking port 80, then nothing would happen at all. Installing it as service did not do a difference. The problem with this is that there were multiple problems, I will describe each problem faced and how to fix it.
