Recently I shifted from Windows XP to Windows Vista. I have been using Windows XP from the past 3 years. I have been very happy with Windows XP. But I thought that I would give a try for Vista also. One of my friends had installed Vista and told me that it was very good. So I thought of giving it a try. there are many versions in Vista and installed the Home Premium version. The OS has got an Aero theme which was very good.
