Early announcements
Windows 8 development started before Windows 7 had shipped
in
2009. In January 2011, at the Consumer Electronics Show (CES), that
Microsoft announced that Windows 8 would be adding support for ARM
microprocessors in addition to the x86 microprocessors from Intel, AMD
and VIA. On June 1, 2011, Microsoft officially unveiled Windows 8's new
user interface as well as additional features at the
Taipei Computex 2011 in Taipei (Taiwan) by Mike Angiulo and at the
D9 conference
in California (United States) by Julie Larson-Green and Microsoft's
Windows President Steven Sinofsky.A month before the BUILD conference
was held, Microsoft opened a new blog called "Building Windows 8" for
users and developers on August 15, 2011.
Developer Preview

Microsoft unveiled new Windows 8 features and improvements on the first
day of the BUILD conference on September 13, 2011. Microsoft also
released the Windows Developer Preview (build 8102) of Windows 8 the
same day, which included SDKs and developer tools (such as Visual
Studio Express and Expression Blend) for developing applications for
Windows 8's new interface. According to Microsoft, there were more than
500,000 downloads of the developer preview within the first 12 hours of
its release.The Developer Preview also introduced the Start screen. The
Start button in the desktop opened the Start screen instead of the
Start menu.
On 16 February 2012, Microsoft postponed the expiration date of the
developer preview. Originally set to expire on 11 March 2012, this
release is now set to expire on 15 January 2013
Final version
On August 1, 2012, Windows 8 (build 9200) was released to
manufacturing. Microsoft plans to release Windows 8 for general
availability on October 26, 2012.However, only a day after its release
to manufacturing, a copy of the final version of Windows 8 Enterprise N
(produced for European markets) leaked to the web and several days
later there were Professional and Enterprise leaks both x86 and x64. On
August 15, 2012, Windows 8 was made available to download for MSDN and
TechNet subscribers Windows 8 was made available to Software Assurance
customers on August 16, 2012.Windows 8 was made available for student
downloads (with a DreamSpark Premium subscription) on August 22, 2012,
earlier than advertised.
Relatively few changes were made from the Release Preview to the final
version. A tutorial explaining how to use the new Metro interface was
included and the look and feel of the desktop was subtly changed to be
more in line with the Metro interface. Some included
apps were also changed slightly.
New features

| This section needs additional citations for verification. (September 2012) |
Desktop and shell
Windows 8 employs a new user interface based on Microsoft's Metro design
language. The environment features a new tile-based Start screen
similar to that of the Windows Phone operating system, which has
replaced the previous Start menu entirely. The Start screen displays a
customizable array of tiles linking to various apps and desktop
programs, some of which can display constantly updated information and
content through "live tiles". As a form of multi-tasking, apps can also
be snapped to the side of a screen
.
A vertical toolbar known as the charms bar (accessed by swiping from the
right edge of a touchscreen, or pointing the cursor at hotspots in the
right corners of a screen) provide access to system and app-related
functions, such as search, sharing, device management, settings, and a
Start button. The traditional desktop environment for running desktop
applications is accessed via a tile on the new Start screen. The Start
button from previous versions of Windows has been removed from the
taskbar in favor of a hotspot in the bottom-left corner (but can still
also be activated via a button on the device if applicable, or on the
charms bar).
Apps and the desktop can be switched between by either swiping from the
left edge of a touchscreen, clicking in the top-left corner of the
screen, using Alt+Tab, or by pointing in the top-left corner and moving
the cursor down to reveal a thumbnail list of active apps.
Apps

Windows 8 introduces a new type of application codenamed
Metro-style apps
(in reference to the Metro design language). Microsoft developer Jensen
Harris described these new apps as having a "fast and fluid"
experience, referring to their increased optimization for touchscreen
input, and their smaller scope than desktop applications. These apps
can run either in a full-screen mode, or be docked directly to the side
of a screen. They are primarily distributed and updated through the
Windows Store, a new distribution platform comparable to the
App Store
and Google Play. These apps can also provide notifications, and provide
dynamic content through a "live tile" on the Start screen.
The apps run within a new set of APIs known as the Windows Runtime
(WinRT), which supports programming languages such as C, C++, VB.NET,
C#, along with HTML5 and JavaScript. WinRT also provides "contracts", a
system which allows apps to to integrate with other apps to provide
functionality such as search and sharing. Apps written for WinRT are
also cross-compatible with both Intel-compatible and ARM versions of
Windows.
To ensure stability and security, WinRT apps run within a sandboxed
environment, and require permissions to access certain functionality,
such as accessing the internet or a camera. For quality and security
reasons, retail versions of Windows 8 will only be able to install
these apps through the Windows Store; the enterprise version will allow
system administrators to deploy internally-developed apps.
Originally described as "Metro-style apps", the term was reportedly
phased out in August 2012; a Microsoft spokesperson denied rumors that
the change was related to a trademark issue, and stated that "Metro" was
only a codename that would be phased out prior to Windows 8's
release. Following these reports, the terms "Modern UI-style
apps", "Windows 8-style apps" and "Windows Store apps"began to be used
in some areas to refer to the new apps.
Integration with online services
Windows 8 provides heavier integration with Microsoft's online services.
Users can now log in with a Microsoft account (formally known as a
Windows Live ID), which can allow for various user settings to be
synchronized between multiple computers. Windows 8 ships with an app for
Microsoft's
SkyDrive cloud storage service
as well, and also allows apps to save files directly to SkyDrive as
well. A SkyDrive client for the traditional desktop and File Explorer is
not included in Windows 8, and must be downloaded separately.Windows 8
also includes integration with Xbox Live, including Xbox-branded apps
for games, music and video, and the SmartGlass app which can serve as a
companion for content on a Xbox 360 video game console
Apps can also integrate with other online services; the People app can
integrate with a variety of different social networks and services,
while the Photos app provides support for photos from services such as
Facebook and Flickr.
Other features
Bootable Windows To Go USB flash drive
- Internet Explorer 10 is included as both desktop program and as a
touch-optimized app. The latter does not support plugins or ActiveX
components, but includes a version of Adobe Flash Player that is
optimized for touch and low power usage and works only on sites included
on a whitelist.
- It is now possible to log into Windows using a Microsoft account
(formerly known as a Windows Live ID). This allows the user's profile
and settings to be synchronized over the Internet and accessible from
other computers running Windows 8, as well as integration with SkyDrive.
- Two new authentication methods have been added: picture password,
which allows users to log in by drawing three gestures in different
places on a picture, and PIN log in, which allows users to authenticate
using a four digit pin.
- File Explorer includes a ribbon toolbar, and has its file operation
progress dialog updated to provide more detailed statistics, the
ability to pause file transfers, and improvements in the ability to
manage conflicts when copying files.
- Hybrid Boot uses hibernation technology to allow faster startup
times by saving the Windows core's memory to the hard disk and reloading
it upon boot.
- Windows To Go allows Windows 8 Enterprise to boot and run from a bootable USB device (such as a flash drive).

Tablets and convertibles
Microsoft released minimum hardware requirements for new tablet and
convertible devices designed for Windows 8, and defined a convertible
form factor as a standalone device that combines the PC, display and
rechargeable power source with a mechanically attached keyboard and
pointing device in a single chassis. A convertible can be transformed
into a tablet where the attached input devices are hidden or removed
leaving the display as the only input mechanism.

field communication need to have visual marks to help users locate and
use the proximity technology. The new button combination for Ctrl + Alt
+ Del is Windows Key + Power. |
Secure boot
See also: Unified Extensible Firmware Interface#Secure_Boot_2 and Hardware restrictions#Windows 8
Secure boot is a feature of UEFI that prevent unauthorized programs from
running at boot time. The inclusion of this feature in Windows 8,
however, has proven controversial.
Hardware makers who choose the optional Microsoft Certification are
required to implement UEFI secure boot. Microsoft also requires that
manufacturers offer the ability to turn off the secure boot feature on
x86 hardware, but they must not offer such an option on ARM hardware. No
mandate is made regarding the installation of third-party certificates
that would enable running alternative software.
In September 2011, Matthew Garrett, an employee of competitor Red Hat,
raised the possible risk of Microsoft locking out alternative
systems, leading to media coverage. Microsoft addressed the issue in a
blog post, stating that
"At the end of the day, the customer is in
control of their PC. Microsoft’s philosophy is to provide customers
with the best experience first, and allow them to make decisions
themselves", with the promise that disabling SecureBoot on Windows 8
devices would be possible. In January 2012, Microsoft released
certification requirements for Windows 8 specifying that non-ARM devices
must have
"the ability to disable Secure Boot", whereas for ARM-based devices, disabling Secure Boot
"must not be possible." By
prohibiting Windows 8 from running on ARM systems that allow the user
to disable Secure Boot, Microsoft raised concerns,particularly in the
Linux community, who are concerned that this marks an attempt by
Microsoft to exclude competing operating systems from computers built
to be compatible with Windows 8.
Fedora Linux has resolved this issue by purchasing a security key from
VeriSign for US$99. The Free Software Foundation has commented on the
issue, covering the use of GRUB and both Ubuntu and Fedora's approaches
.
Software compatibility
Windows 8 for IA-32 and x64 processors runs most software compatible
with previous versions of Windows, with the same restrictions as
Windows 7: 64-bit Windows 8 runs 64-bit and 32-bit software while
32-bit Windows 8 will be able to run 32-bit and 16-bit software
(although some 16-bit software may require compatibility settings to be
applied, or not work at all).
Windows RT, a version of Windows 8 for systems with ARM processors, only
supports applications included with the system (such as a special
version of , supplied through Windows Update, or applications acquired
through the Windows Store. Windows RT does not support running existing
IA-32 or x64 desktop applications to ensure the quality of apps
available on ARM.
Metro-style applications can either be cross-compatible between Windows
8 and Windows RT, or compiled to support a specific architecture.
Upgrade offers
Logo
On
February 18, 2012, Microsoft confirmed that in Windows 8 the Windows
logo will be significantly updated to reflect the new Metro design
language. The logo was designed by Pentagram partner Paula Scher. The
formerly flag-shaped logo has been transformed into four window panes,
perspective was added, and the entire logo will be rendered in a single
solid color, which will depend on the user's personalization changes.
