I was highly unsatisfied with my current windows XP operating system as it got used to repair quite often and the blue screen of death gets displayed very often. Then the entire drive has to be formatted and the operating system has to be re installed. I told the problem to one of my friends who is a technician in a computer dealer show room and he said that he was having the windows xp home edition and I went to the shop and got the CD. My friend wrote the windows xp home product key in a sheet of paper and gave it to me. I started installing the operating system using the boot disk given to me.

The windows xp home product key was very useful and I entered the product key while installing the operating system and it took about 40 minutes to install the windows xp home edition. This edition of the operating system had only limited features and a lot of features that was in the earlier edition were missing in the home edition. The difference between the professional and home edition of the operating system lies in the variety of features that it provides. The problem with the operating system was solved temporarily and I gave the boot CD and the windows xp home product key sheet to my friend and thanked him. I enquired him about the operating system that is being installed in the computers in the dealer show room. My friend told that the windows 2007 operating system was installed and the operating system has advanced features than the previous editions of the operating system. All the editions of the operating system released by Microsoft and all editions have the respective product keys. The product keys are a means of authorization of the operating system and the windows xp home product key is used to activate only the home edition and cannot be used to activate other editions of the windows operating system. Each windows operating system will be having a unique 16 digit product key to activate the operating system and this is very essential for the installation of the operating system. All the product keys are released as a note pad text file and comes along with the operating CD or can be obtained along with the purchase of the genuine operating system in the select retail outlets or online in the Microsoft web site.
