Microsoft's big Windows 10 event hasn't gotten underway just yet, but we've already gotten a brief glimpse of what's to come for tablets. Pictured here is Dell's Venue 11 Pro running none other than Microsoft's latest operating system. You can clearly see some of the design changes that Microsoft has made to the Start Screen. It looks largely similar to the "Continuum" preview we saw back in September, but the company looks to have made some significant development progress since then. Search is running on the left side, though sadly there are no immediate signs of Cortana and other major additions to Windows 10 we're expecting to hear about in less than an hour. You'd be crazy to miss it, so be sure to follow every minute at our Windows 10 event live blog starting at 12PM ET.
