One of my sources confirmed this is now looking like the plan and added that Microsoft is also considering bringing back the Start button as an option with Windows Blue.
I take this as yet another confirmation that Microsoft is moving toward make the boot-to-desktop option and some kind of Windows Start button a part of Windows Blue. I don't know if these options are likely to be available across all Windows 8 and Windows RT SKUs (or just Pro and Enterprise, which is what my Windows Weekly cohost Paul Thurrott is hearing.) I also don't know if this Start Button will just be something that brings users directly to the Metro Start Screen. But I'd be that's far more likely than something that would bring them back to the old Start Menu.
Previously in build 9374, a "Kiosk" mode was uncovered that allows the device user profile to be locked down to a single app – this is now called "Assigned Access". Another change in the new build is app settings that allow users to choose an app that can show alarms on the lock screen, meaning there's a good chance app-specific notifications and alarms will flash on a locked device similar to the way messages surface on Apple's iOS. So far existing Windows 8 apps do not support this feature.
What still hasn't made an obvious appearance, despite recent reports, is the revamped Start button for desktop users that only leads to the Start screen, and the boot to desktop mode. Microsoft is reportedly still working on that, and could be in place by the time the Redmond company supposedly launches the Public Preview during BUILD 2013 in June.
If it's just to toggle back and forth to the start screen they still aren't going to satisfy the people that want the traditional start button with programs and power buttons.
