Do be forewarned that the preview page itself would be pretty hefty when it comes to photos and graphics, so if you are an information-heavy kind of person, you might end up to be rather disappointed. Still, there is a link here that would lead those who are interested to a “What’s New in Windows 8.1” page, where it would carry a whole lot more information concerning a free upgrade. Microsoft has plans to roll out the free preview version of Windows 8.1 that will be accompanied by a preview build of Windows Embedded 8.1 Industry as well as a new update to Windows RT this coming June 26, although you can expect a final release to roll out later this year.
