I bought new HP laptop with Vista home on it last August and both the laptop and the OS is junk - most terrible experience I've ever had in my life. I tried downgrading but vista won't let me do it easily. There must be a way! I see some the correpondence abt having to purchase full XP version. I have old laptop where I have licence for Windows XP Professional. Has anyone successfully downgraded from Vista to XP? Can anyone pls help....
