purchased laptop with Vista preinstalled from PC World about 3 or 4 months ago and turned it on today only to get a message saying that Vista cannot be validated, tried re-entering my product code but it says it is invalid. Why has this suddenly happened and how can i rectify it?? Please can anyone help?? Thanks, Fiona
Please also post the error code you get (if any) when you validate by clicking "Validate Windows" here: www.microsoft.com/genuine The error code will be gray and in brackets at the end of the message on the page that says validation failed. (It'll look something like this: [0xC004C000]).
