How to install Windows XP inside Vista using Virtual PC 2007?

I have Vista Home Basic OS in my laptop. It doesn't allow me to install IIS (Internet Information Services) which I need for my programming requirements. Even I was wondering how to get over this situation. Finally I found answer to this.

I installed Virtual PC 2007 in my Vista OS machine and then installed Windows XP in Virtual PC. I followed the clearly mentioned steps from below link.
