Build 9364 of Windows Blue said leaked through French partner
A leaked copy of what is claimed to be Windows Blue has appeared on file sharing sites, ahead of the updates public preview. The downloadable ISO file, weighing in at 2.63GB, is said to have come from a Microsoft partner based in France, and shows a number of adjustments to the operating system, including a choice of smaller and larger Live Tiles for the Start screen.
Multi-tasking has been improved for apps, including the option to run two with a split in the middle of the screen, allowing both to have the same application width, according to Neowin. More accent colors, deeper SkyDrive integration, and updates to the side Charms are also making an appearance. Internet Explorer is also usable in the leaked copy, but it isn't clear what improvements have been made to the browser.
Windows Blue is expected to become available as a public preview in the next few months, with a view to a release towards the end of this year.
