Windows 8 is the codename for the upcoming new
operating system of Microsoft Windows that follows Windows 7.
It features a new Metro-style interface that was designed for
touchscreen, mouse, keyboard,
and pen input.
It also adds support for the ARM processor
architecture in addition to the previously
supported x86 microprocessors from Intel and AMD.
Its server counterpart is codenamed Windows Server 8.
The Windows 8 is designed to be the first
Windows client to support systems on a chip
(SoC) architectures, including ARM,
and since it will be pre-installed on a range
of next generation devices, it will also feature Metro,
a NUI + GUI interface
on the surface combined with a new
application platform under-the-hood designed
to enable the creation of immersive experiences.
Windows 8 Release Preview is a prerelease version
of Windows 8 that focuses on people and apps and gives you powerful new ways to use social technologies to connect with the people who are important to you. It’s Windows reimagined. Windows 8 Release Preview is built on the rock-solid foundation of Windows 7 and has the security and reliability features you expect from Windows, but we’ve made it even better. It’s fast, and it’s made to work on a variety of form factors—especially the new generation of touch devices.
Many are interested in Windows 8 for ARM processors. Everything we showcased today at BUILD also runs on the ARM-....d Windows PCs being created by ARM partners and PC manufacturers. Windows 8 running on ARM will ultimately be available with ARM-....d hardware that you can purchase. ARM requires a deeper level of integrated engineering between hardware and software, as each ARM device is unique, and Windows allows this uniqueness to shine through. The new development tools enable you to start today to build Metro style applications that will seamlessly run on x86 (32 and 64 bit) or ARM architectures. Even if you use native C/C++ code, these tools will enable Metro style apps to target specific hardware if you choose. As new PCs become available for testing, PC manufacturers will develop seed programs for developers.
The company also highlighted a variety of new features in Windows 8, including the following:
Touch-First User Interface
• Metro style. Windows 8 introduces a new Metro style interface built for touch, which shows information important to you, embodies simplicity and gives you control. The Metro style UI is equally at home with a mouse and keyboard as well.
• Touch-first browsing, not just browsing on a touch device. Providing a fast and fluid touch-browsing experience, Internet Explorer 10 puts sites at the center on new Windows 8 devices.
More Ways to Engage With Powerful, Connected Apps
• Powered by apps. Metro style apps built for Windows 8 are the focal point of your experience, filling your entire screen so there are no distractions.
• Apps can work together. Apps communicate with each other in Windows 8. For example, you can easily select and email photos from different places, such as Facebook,
Flickr or on your hard drive.
• Your experience syncs across your devices.
Live roams all the content from the cloud services you
use most – photos, email,
calendar and contacts – keeping them
up-to-date on your devices. With SkyDrive,
you can access your files,
photos and ********s from virtually anywhere with any browser
or with Metro style apps in Windows 8.
Enhanced Fundamentals
• The best of Windows 7, only better.
Windows 8 is built on the rock-solid foundation of Windows 7,
delivering improvements in performance,
security, privacy and system reliability.
Windows 8 reduces the memory footprint
needed – even on the lowest-end hardware
– leaving more room for your apps.
• Preserving power-user favorites and
making them better.
For those who push the limits of their PC,
Windows 8 features an enhanced Task Manager and
Windows Explorer and new, flexible options for
multimonitor setups.
New Generation of Hardware
• One Windows – many shapes and sizes.
Support for ARM-....d chipsets, x86
(as well as x32 and x64) devices, touch and
sensors means Windows 8 works
beautifully across a spectrum of devices,
from 10-inch tablets and laptops to
all-in-ones with 27-inch high-definition screens.
• Always connected. With Windows 8,
new ultrathin PCs and
tablets turn on instantly, run all day on a single charge and
stay connected to the Internet so your PC is ready when you are. Next-generation system on a chip (SoC) support will also enable greatly extended standby and low-power states.
• Tap the full power of your PC. Windows 8 runs on PCs and
is compatible with the devices and
programs you use today on Windows 7,
without compromise,
to deliver the performance you expect of a PC.
