Join us for Microsoft's Windows 8 press conference tomorrow at 9:30am EST!

If you're Microsoft and in the process of overhauling Windows so that it's equally at home on PCs and tablets, it would make sense to unveil a semi-final version at the world's premier wireless show. That's exactly what's going to happen tomorrow, when the company's executive team takes the stage here in Barcelona to show off all the changes it's made to Win8 since we got hands-on with the Developer Preview five months ago. Though we still won't know tomorrow what the final version will look like, we'll have a much firmer idea, as this will be the first version available to the general Windows-using populace. So what does Redmond have up its sleeve? Will the Windows Store open for business? A first look at some native touch-friendly apps? And what's to become of the Start button? Bookmark this page and come back tomorrow at 9:30am EST (3:30pm local time), when we'll be firing off up-to-the-minute updates. See you then!

Microsoft reveals Windows 8's new logo: 'It's a window... not a flag'

Microsoft is making plenty of big changes with its Windows 8 operating system, and that has now also extended to a new logo. As explained by Microsoft's Sam Moreau in a post on the official Windows blog, the logo was created with the help of the design agency Pentagram, which posed a simple question when it began on the project: "your name is Windows. Why are you a flag?" That discussion eventually led to the four-paned window you see above, which not only looks more like a window than the previous logos, but clearly echoes the company's new Metro design language. Microsoft also notes that the logo is "authentically digital," and says it will welcome you with a slight tilt and change color based on your desktop.
