One of the most talked about is that Windows 8 dispenses with the familiar Start button, and instead will feature a "hot corner", swiping or mousing over which will allow users to toggle between Metro and the standard Windows Explorer Interface. Windows 8 Consumer Preview should either confirm this rumor or put it to rest for good.
6. Logo redesigned? Ditto for the familiar, multi-colored, multi-paned Windows logo. Internet reports, mostly based on blogs originating out of Asia, suggest that Windows 8 will ditch the old logo and instead bear a monochromatic or grayscale emblem that's been streamlined considerably.
While that might be less pretty, it would be consistent with the new interface that Microsoft has developed for Visual Studio 11, which is optimized for building Windows 8 apps. (Windows 8 Consumer Preview, however, is not supported in Visual Studio 11 Beta.)
7. Apps story. Microsoft has not confirmed that any new Windows 8 Metro apps will be available for consumers to download alongside Windows 8 Consumer Preview tomorrow, but it's a good bet there will be at least some software ready for users to play around with in order to get a feel for how using tablet-style apps plays out on a PC.
At least one major newspaper publisher has confirmed that it plans to produce a Windows 8 app, national news giant USA Today.
8. Windows Store. Speaking of apps, Microsoft will also open its Windows Store application market for a preview on Wednesday. Again, it's not known if any actual apps will be there to purchase, but it should be enough to allow users to see how the store operates and compare the process to Apple's App Store or Google's Android Market.
The download and checkout process will need to be seamless, as Microsoft has said that the Windows Store will be the only source of Metro-style apps for Windows 8 PCs and tablets.
Microsoft plans to formally introduce Windows 8 Consumer Preview during an event at World Mobile Congress that starts at 9 a.m. Eastern time (3 p.m. local time in Barcelona). It should be available at some point after that, though the company has not provided an exact release time.
