My uncle bought a laptop which was running Microsoft windows vista. That operating system had a ton of bugs, sometimes the laptop just stuck in the middle of nowhere, sometimes hardware recognition(drivers) wont takes place. Even laptops own drivers like touch pad drivers was not recognize. then my uncle switched it back to windows xp. when they switched back all was working fine. there was no any issue. So in another language we can say - windows xp has saved microsoft’s life. if you are going to buy a new operating system then please do not buy this vista as operating system.
