Hello,

My name is John,,,I am from Nigeria?
Last year 2014,my uncle bought me a new hcl laptop from India and brought it to me for personal use,it came with a Microsoft Xp, while I was using it everything in it was working perfectly well including the wifi,bluetooth and webcam..so after some time I changed the operating system to a Windows 7,which was ok so after sometime the windows7 started developing faults and problem which I couldn't solve alone now I reinstall it for a new windows7,it was still repeating the same thing..
So now i want u people to please recommend a best windows xp or which I can install in my laptop and be able to enjoy it because the windows7 has damage my keyboard which is mal-functioning..Thanks?
