Multi-Monitor Setup
New support for multiple monitors lets you span a background image across screens (more appropriate for similar-size monitors), and you can invoke the charm icons on each screen, with a forgiving target areas in the upper-right corner of each. Here we see a 46-inch Samsung UN46ES8000F as the secondary monitor.
Windows 8 Lock Screen
The next time you start up your Windows 8 tablet or PC, you'll see a lock screen like this. Note that it displays notifications for the number of emails waiting, battery level, and Wi-Fi signal strength.
Charms and Status
When you swipe in from the right or move the mouse cursor to the top right corner of the screen, you'll see the "Charms" or menu icons on the right for Search, Share, Start, Devices, and Settings. You'll also see the time, date, battery status, and Wi-Fi status on the left.
Sports App 
New for Windows 8 Release Candidate is this Sports app. Note the use of large icons, invokes with a right mouse click or a swipe down.
Pin App Section 
In Windows 8 Metro, you can not only pin apps to the start page, but subsections of apps. Here, in the Sports app, I'm pinning the Mets section. You can also pin a specific stock symbol or email inbox.
Choose a Background Color
New for the Release Preview of Windows 8 is a selection of background 26 colors. The new Windows logo changes color to match your selection.
Wireless Setup
The next step before you start using your new Windows 8 tablet is to sign into a Wi-FI access point.
Settings
The Settings part of setup is more complex, but it will make sense for most people to simply choose Express settings, which turns on security and auto updates.
Sign in to your PC
Before you can fully use Windows 8, just as with any smart mobile device, you need to sign into an online account. This enables the app store, syncing, and online cloud storage using SkyDrive.
Windows 8 Start Screen
After the simple setup, you'll see this tile-based Metro UI Start screen. Note there are fewer included apps than in the Windows 8 Consumer Preview, but that can easily be remedied by a visit to the Windows Store.
Picture Password
To make it easier to log in to a touch tablet, you can set up a Picture Password. This lets you log it with a set sequence of taps, line, and circles on an image of your choice.
Picture Password Gesture Setup
You just need three gestures, which you repeat and accept when setting up your picture password.
Semantic Zoom
If you pinch the Start screen your tiles will shrink, showing all at once. This makes moving tiles and general navigation easier.
Search
Just start typing from the Start screen, and search results will appear like this. You can filter results by app, settings, or files, and even search within any of the apps listed at lower right.
Sidebar
You can get a partial view of a second app by swiping in and holding from the left.
People App and Running App Sidebar
This shot shows the People app, which lets you hook up your Facebook, Twitter, and other social accounts. It also shows the left panel of other running apps, which you call up by swiping to the left edge and them back in, or, with the mouse, by putting the cursor in the top left corner and then moving down.
Video App and Sidebar
One of the included apps that come with Windows 8 Release Preview is this Video app, which lets you buy and rent from the Zune Market. This screen also shows how you can get a partial view of a second app, in this case the Pictures app, in a sidebar.
Devices 
In Settings you can find and connect to wireless devices.
Multiple Monitors
Just as in Windows 7, you can view your Windows 8 on multiple monitors. This setting is available from the Devices charm.
Internet Explorer in Windows 8 
There are actually two views of Internet Explorer, this is the touch-centric Metro view. It's full screen on the Web page, but if you swipe up from the bottom or down from the top, you see the thumbnails at the top and the address bar, pinning, and settings icon at the bottom. The thumbnails show loaded sites, and note that you can "Clean Up" or close all but the current window. The Metro browser now supports some Flash sites, and has a Flip-Ahead feature, taking you to the most likely next page.
The New "Start" Button
This mini view of the Metro start screen appears when you move the mouse to the lower left corner of the screen. Clicking there opens the start screen.
The New Desktop Explorer
The Windows Explorer now has a ribbon, but now you can hide it with the up arrow at upper right.
Task Manager
Task Manager has been redesigned, showing App history and more performance views, and color coding.
Pen Input
Windows 8 supports stylus input, and it did a good job of converting my writing to characters.
