Vista retail release date: 30 January 2007

Mark 30 January 2007 in your diary because that's when the average consumer will be able to get their hands on Microsoft's new Windows Vista operating system.

Following months of speculation, Microsoft has revealed that Vista will be on shelves and pre-installed on new computers on the second-to-last day of January.

It was announced last week that Vista will be released to business users with volume license deals on 30 November but the retail customers will have to wait another two months.
