Acer's European vice-president Massimo D'Angelo has revealed that Windows 7 will be shipping on Acer computers by 23 October this year - three months earlier than Microsoft's official January 2010 date.

In a press conference today, with TechRadar in attendance, it was announced by Acer that the company's Aspire Z5600 all-in-one multi-touch PC (which the company called Everyone's AIO in its presentation) would be available in stores from the end of September for customers to try out.

The Windows 7 revelation came when one journalist asked if he had just given the release date for Microsoft's next OS away, with D'Angelo stipulating that "he had not".

He went on to say that the Windows 7-powered computer would only be available to purchase on the 23 October "and not a day before".
