Microsoft Windows or Windows is a
superfamily of graphical operating
systems developed, marketed, and
sold by Microsoft. It consists of
several families of operating
systems, each of which cater to a
certain sector of the computing
industry. Active Windows families
include Windows NT , Windows
Embedded and Windows Phone;
these may encompass subfamilies,
e.g. Windows Embedded Compact
(Windows CE) or Windows Server .
Defunct Windows families include
Windows 9x and Windows Mobile .
Microsoft introduced an operating
environment named Windows on
November 20, 1985 as a graphical
operating system shell for MS-DOS
in response to the growing interest
in graphical user interfaces (GUIs).
[5] Microsoft Windows came to
dominate the world's personal
computer market with over 90%
market share, overtaking Mac OS ,
which had been introduced in 1984.
However, it is outsold by Android on
smartphones and tablets. [6][7][8]
As of April 2014, the most recent
versions of Windows for personal
computers, smartphones , server
computers and embedded devices
are respectively Windows 8.1 ,
Windows Phone 8.1 , Windows
Server 2012 R2 and Windows
Embedded 8. A specialized version
of Windows runs on the Xbox One
game console.
Genealogy
By marketing role
Microsoft, the developer of
Windows, has registered several
trademarks each of which denote a
family of Windows operating
systems that target a specific
sector of the computing industry. As
of 2014, the following Windows
families are being actively
developed:
Windows NT : Started as a family
of operating system with Windows
NT 3.1 , an operating system for
server computers and workstations .
It now consists of three operating
system subfamilies that are
released almost at the same time
and share the same kernel
Windows: The operating
system for mainstream personal
computers . The latest version is
Windows 8.1 . It is almost
impossible for someone
unfamiliar with the subject to
identify the members of this
family by name because they do
not adhere to any specific rule;
e.g. Windows Vista , Windows 7
and Windows RT are members of
this family but Windows 3.1 is
not. The main competitor of this
family is OS X by Apple Inc. (c.f.
Usage share of operating
systems § Market share by
category )
Windows Server : The
operating system for server
computers. The latest version is
Windows Server 2012 R2 . Unlike
its clients sibling, it has adopted
a strong naming scheme. The
main competitor of this family is
Linux . (c.f. Usage share of
operating systems § Market
share by category )
Windows PE: A lightweight
version of its Windows sibling
meant to operate as a live
operating system , used for
installing Windows on bare-
metal computers (especially on
many computers at once),
recovery or troubleshooting
purposes. The latest version is
Windows PE 5.1.
Windows Phone : An operating
system sold only to manufacturers
of smartphones. The first version
was Windows Phone 7 . The latest
version is Windows Phone 8.1 . The
main competitor of this family is
Android by Google . (c.f. Usage
share of operating systems §
Market share by category)
Windows Embedded : Initially,
Microsoft developed Windows CE as
a general-purpose operating system
for every device that was too
resource-limited to be called a full-
fledged computer. Eventually,
however, Windows CE was renamed
Windows Embedded Compact and
was folded under Windows Compact
trademark which also consists of
Windows Embedded Industry,
Windows Embedded Professional,
Windows Embedded Standard ,
Windows Embedded Handheld and
Windows Embedded Automotive.[9]
The following Windows families are
no longer being developed:
Windows 9x : An operating that
targeted consumers market.
Discontinued because of suboptimal
performance. ( PC World called its
last version, Windows ME , one of
the worst products of all times.) [10]
Microsoft now caters to the
consumers market with Windows
NT.
Windows Mobile : The
predecessor to Windows Phone, it
was a mobile phone operating
system. The first version was
called Pocket PC 2000 ; the third
version, Windows Mobile 2003 is
the first version to adopt the
Windows Mobile trademark. The
last version is Windows Mobile 6.5 .
Version history
Main article: History of Microsoft
Windows
See also: List of Microsoft Windows
versions
The term Windows collectively
describes any or all of several
generations of Microsoft operating
system products. These products
are generally categorized as
follows:
Early versions
Main articles: Windows 1.0 ,
Windows 2.0 and Windows 2.1x
Windows 1.0 , the first version,
released in 1985
The history of Windows dates back
to September 1981, when Chase
Bishop, a computer scientist,
designed the first model of an
electronic device and project
"Interface Manager" was started. It
was announced in November 1983
(after the Apple Lisa , but before the
Macintosh) under the name
"Windows", but Windows 1.0 was
not released until November 1985.
[11] Windows 1.0 was to compete
with Apple's operating system, but
achieved little popularity. Windows
1.0 is not a complete operating
system; rather, it extends MS-DOS .
The shell of Windows 1.0 is a
program known as the MS-DOS
Executive. Components included
Calculator, Calendar, Cardfile,
Clipboard viewer , Clock, Control
Panel, Notepad , Paint , Reversi,
Terminal and Write . Windows 1.0
does not allow overlapping
windows. Instead all windows are
tiled. Only modal dialog boxes may
appear over other windows.
Windows 2.0 was released in
December 1987 and was more
popular than its predecessor. It
features several improvements to
the user interface and memory
management. [citation needed]
Windows 2.03 changed the OS from
tiled windows to overlapping
windows. The result of this change
led to Apple Computer filing a suit
against Microsoft alleging
infringement on Apple's copyrights.
[12][13] Windows 2.0 also
introduced more sophisticated
keyboard shortcuts and could make
use of expanded memory.
Windows 2.1 was released in two
different versions: Windows/286
and Windows/386 . Windows/386
uses the virtual 8086 mode of Intel
80386 to multitask several DOS
programs and the paged memory
model to emulate expanded memory
using available extended memory.
Windows/286, in spite of its name,
runs on both Intel 8086 and Intel
80286 processors. It runs in real
mode but can make use of the high
memory area .
In addition to full Windows-
packages, there were runtime-only
versions that shipped with early
Windows software from third
parties and made it possible to run
their Windows software on MS-DOS
and without the full Windows
feature set.
The early versions of Windows are
often thought of as graphical shells,
mostly because they ran on top of
MS-DOS and use it for file system
services. [14] However, even the
earliest Windows versions already
assumed many typical operating
system functions; notably, having
their own executable file format and
providing their own device drivers
(timer, graphics, printer, mouse,
keyboard and sound). Unlike MS-
DOS, Windows allowed users to
execute multiple graphical
applications at the same time,
through cooperative multitasking.
Windows implemented an elaborate,
segment-based, software virtual
memory scheme, which allows it to
run applications larger than
available memory: code segments
and resources are swapped in and
thrown away when memory became
scarce; data segments moved in
memory when a given application
had relinquished processor control.
Windows 3.0 and 3.1
Main articles: Windows 3.0 and
Windows 3.1x
Windows 3.0 , released in 1990
Windows 3.0 , released in 1990,
improved the design, mostly
because of virtual memory and
loadable virtual device drivers
(VxDs ) that allow Windows to share
arbitrary devices between multi-
tasked DOS
applications. [citation needed ]
Windows 3.0 applications can run
in protected mode , which gives
them access to several megabytes
of memory without the obligation to
participate in the software virtual
memory scheme. They run inside
the same address space, where the
segmented memory provides a
degree of protection. Windows 3.0
also featured improvements to the
user interface. Microsoft rewrote
critical operations from C into
assembly. Windows 3.0 is the first
Microsoft Windows version to
achieve broad commercial success,
selling 2 million copies in the first
six months. [15][16]
Windows 3.1, made generally
available on March 1, 1992, featured
a facelift. In August 1993, Windows
for Workgroups, a special version
with integrated peer-to-peer
networking features and a version
number of 3.11, was released. It
was sold along Windows 3.1.
Support for Windows 3.1 ended on
December 31, 2001. [17]
Windows 9x
Main article: Windows 9x
The next major consumer-oriented
release of Windows, Windows 95,
was released on August 24, 1995.
While still remaining MS-DOS-
based, Windows 95 introduced
support for native 32-bit
applications, plug and play
hardware, preemptive multitasking,
long file names of up to 255
characters, and provided increased
stability over its predecessors.
Windows 95 also introduced a
redesigned, object oriented user
interface, replacing the previous
Program Manager with the Start
menu , taskbar, and Windows
Explorer shell. Windows 95 was a
major commercial success for
Microsoft; Ina Fried of CNET
remarked that "by the time Windows
95 was finally ushered off the
market in 2001, it had become a
fixture on computer desktops
around the world." [18] Microsoft
published four OEM Service
Releases (OSR) of Windows 95,
each of which was roughly
equivalent to a service pack . The
first OSR of Windows 95 was also
the first version of Windows to be
bundled with Microsoft's web
browser, Internet Explorer .[19]
Mainstream support for Windows 95
ended on December 31, 2000 and
extended support for Windows 95
ended on December 31, 2001. [20]
Windows 95 was followed up with
the release of Windows 98 on June
25, 1998, which introduced the
Windows Driver Model, support for
USB composite devices, support for
ACPI, hibernation, and support for
multi-monitor configurations.
Windows 98 also included
integration with Internet Explorer 4
through Active Desktop and other
aspects of the Windows Desktop
Update (a series of enhancements
to the Explorer shell which were
also made available for Windows
95). In May 1999, Microsoft
released Windows 98 Second
Edition, an updated version of
Windows 98. Windows 98 SE added
Internet Explorer 5.0 and Windows
Media Player 6.2 amongst other
upgrades. Mainstream support for
Windows 98 ended on June 30, 2002
and extended support for Windows
98 ended on July 11, 2006. [21]
On September 14, 2000, Microsoft
released Windows ME (Millennium
Edition), the last DOS-based version
of Windows. Windows ME
incorporated visual interface
enhancements from its Windows
NT-based counterpart Windows
2000, had faster boot times than
previous versions (which however,
required the removal of the ability to
access a real mode DOS
environment, removing
compatibility with some older
programs), [22] expanded
multimedia functionality (including
Windows Media Player 7, Windows
Movie Maker , and the Windows
Image Acquisition framework for
retrieving images from scanners
and digital cameras), additional
system utilities such as System File
Protection and System Restore, and
updated home networking tools. [23]
However, Windows ME was faced
with criticism for its speed and
instability, along with hardware
compatibility issues and its
removal of real mode DOS support.
PC World considered Windows ME to
be one of the worst operating
systems Microsoft had ever
released, and the 4th worst tech
product of all time. [10]
Windows NT
Main article: Windows NT
Early versions
In November 1988, a new
development team within Microsoft
(which included former Digital
Equipment Corporation developers
Dave Cutler and Mark Lucovsky)
began work on a revamped version
of IBM and Microsoft's OS/2
operating system known as "NT
OS/2". NT OS/2 was intended to be
a secure, multi-user operating
system with POSIX compatibility
and a modular, portable kernel with
preemptive multitasking and
support for multiple processor
architectures. However, following
the successful release of Windows
3.0 , the NT development team
decided to rework the project to use
an extended 32-bit port of the
Windows API known as Win32
instead of those of OS/2. Win32
maintained a similar structure to
the Windows APIs (allowing
existing Windows applications to
easily be ported to the platform), but
also supported the capabilities of
the existing NT kernel. Following its
approval by Microsoft's staff,
development continued on what was
now Windows NT, the first 32-bit
version of Windows. However, IBM
objected to the changes, and
ultimately continued OS/2
development on its own. [24][25]
The first release of the resulting
operating system, Windows NT 3.1
(named to associate it with
Windows 3.1 ) was released in July
1993 with versions for desktop
workstations and servers. Windows
NT 3.5 was released in September
1994, focusing on performance
improvements and support for
Novell's NetWare, and was followed
up by Windows NT 3.51 in May
1995, which included additional
improvements and support for the
PowerPC architecture. Windows NT
4.0 was released in June 1996,
introducing the redesigned interface
of Windows 95 to the NT series. On
February 17, 2000, Microsoft
released Windows 2000 , a
successor to NT 4.0. The Windows
NT name was dropped at this point
in order to put a greater focus on
the Windows brand.[25]
Windows XP
The next major version of Windows,
Windows XP, was released on
October 25, 2001. The introduction
of Windows XP aimed to unify the
consumer-oriented Windows 9x
series with the architecture
introduced by Windows NT, a
change which Microsoft promised
would provide better performance
over its DOS-based predecessors.
Windows XP would also introduce a
redesigned user interface (including
an updated Start menu and a "task-
oriented" Windows Explorer ),
streamlined multimedia and
networking features, Internet
Explorer 6, integration with
Microsoft's .NET Passport services,
modes to help provide compatibility
with software designed for previous
versions of Windows, and Remote
Assistance functionality. [26]
At retail, Windows XP was now
marketed in two main editions: the
"Home" edition was targeted
towards consumers, while the
"Professional" edition was targeted
towards business environments and
power users, and included
additional security and networking
features. Home and Professional
were later accompanied by the
"Media Center" edition (designed for
home theater PCs, with an emphasis
on support for DVD playback, TV
tuner cards, DVR functionality, and
remote controls), and the "Tablet
PC" edition (designed for mobile
devices meeting its specifications
for a tablet computer, with support
for stylus pen input and additional
pen-enabled applications). [27][28]
[29] Mainstream support for
Windows XP ended on April 14,
2009. Extended support ended on
April 8, 2014. [30]
After Windows 2000, Microsoft also
changed its release schedules for
server operating systems; the
server counterpart of Windows XP,
Windows Server 2003, was released
in April 2003. [25] It was followed in
December 2005 by Windows Server
2003 R2.
Windows Vista and later
After a lengthy development
process, Windows Vista was
released on November 30, 2006 for
volume licensing and January 30,
2007 for consumers. It contained a
number of new features, from a
redesigned shell and user interface
to significant technical changes ,
with a particular focus on security
features. It was available in a
number of different editions, and
has been subject to some criticism .
Vista's server counterpart, Windows
Server 2008 was released in early
2008.
On July 22, 2009, Windows 7 and
Windows Server 2008 R2 were
released as RTM (release to
manufacturing) while the former
was released to the public 3 months
later on October 22, 2009. Unlike its
predecessor, Windows Vista, which
introduced a large number of new
features, Windows 7 was intended
to be a more focused, incremental
upgrade to the Windows line, with
the goal of being compatible with
applications and hardware with
which Windows Vista was already
compatible. [31] Windows 7 has
multi-touch support, a redesigned
Windows shell with an updated
taskbar, a home networking system
called HomeGroup ,[32] and
performance improvements.
Windows 8 , the successor to
Windows 7, was released generally
on October 26, 2012. A number of
significant changes were made on
Windows 8, including the
introduction of a user interface
based around Microsoft's Metro
design language with optimizations
for touch-based devices such as
tablets and all-in-one PCs. These
changes include the Start screen,
which uses large tiles that are more
convenient for touch interactions
and allow for the display of
continually updated information, and
a new class of apps which are
designed primarily for use on
touch-based devices. Other
changes include increased
integration with cloud services and
other online platforms (such as
social networks and Microsoft's
own SkyDrive and Xbox Live
services), the Windows Store
service for software distribution,
and a new variant known as
Windows RT for use on devices that
utilize the ARM architecture .[33]
[34][35][36][37][38] An update to
Windows 8, called Windows 8.1 ,
was released on October 17, 2013,
and includes features such as new
live tile sizes, deeper SkyDrive
integration, and many other
revisions.[39]
On September 30, 2014, Microsoft
announced Windows 10 as the
successor to Windows 8.1. It will
be released in late 2015 and
addresses shortcomings in the user
interface first introduced with
Windows 8. Changes include the
return of the Start Menu, a virtual
desktop system, and the ability to
run Windows Store apps within
windows on the desktop rather than
in full-screen mode. [40]
Multilingual support
Multilingual support is built into
Windows. The language for both the
keyboard and the interface can be
changed through the Region and
Language Control Panel.
Components for all supported input
languages, such as Input Method
Editors , are automatically installed
during Windows installation (in
Windows XP and earlier, files for
East Asian languages, such as
Chinese, and right-to-left scripts,
such as Arabic, may need to be
installed separately, also from the
said Control Panel). Third-party
IMEs may also be installed if a user
feels that the provided one is
insufficient for their needs.
Interface languages for the
operating system are free for
download, but some languages are
limited to certain editions of
Windows. Language Interface Packs
(LIPs) are redistributable and may
be downloaded from Microsoft's
Download Center and installed for
any edition of Windows (XP or later)
- they translate most, but not all, of
the Windows interface, and require
a certain base language (the
language which Windows originally
shipped with). This is used for most
languages in emerging markets. Full
Language Packs, which translates
the complete operating system, are
only available for specific editions
of Windows (Ultimate and
Enterprise editions of Windows
Vista and 7, and all editions of
Windows 8, 8.1 and RT except
Single Language). They do not
require a specific base language,
and are commonly used for more
popular languages such as French
or Chinese. These languages cannot
be downloaded through the
Download Center, but available as
optional updates through the
Windows Update service (except
Windows 8).
The interface language of installed
applications are not affected by
changes in the Windows interface
language. Availability of languages
depends on the application
developers themselves.
Windows 8 and Windows Server
2012 introduces a new Language
Control Panel where both the
interface and input languages can
be simultaneously changed, and
language packs, regardless of type,
can be downloaded from a central
location. The PC Settings app in
Windows 8.1 and Windows Server
2012 R2 also includes a counterpart
settings page for this. Changing the
interface language also changes the
language of preinstalled Windows
Store apps (such as Mail, Maps and
News) and certain other Microsoft-
developed apps (such as Remote
Desktop). The above limitations for
language packs are however still in
effect, except that full language
packs can be installed for any
edition except Single Language,
which caters to emerging markets.
Platform support
Windows NT included support for
several different platforms before
the x86 -based personal computer
became dominant in the
professional world. Windows NT
4.0 and its predecessors supported
PowerPC , DEC Alpha and MIPS
R4000. (Although some these
platforms implement 64-bit
computing, the operating system
treated them as 32-bit.) However,
Windows 2000, the successor of
Windows NT 4.0, dropped support
for all platforms except the third
generation x86 (known as IA-32 ) or
newer in 32-bit mode. The client
line of Window NT family still runs
on IA-32, although the Windows
Server line has ceased supporting
this platform with the release of
Windows Server 2008 R2 .
With the introduction of the Intel
Itanium architecture (IA-64),
Microsoft released new versions of
Windows to support it. Itanium
versions of Windows XP and
Windows Server 2003 were
released at the same time as their
mainstream x86 counterparts.
Windows XP 64-Bit Edition,
released in 2005, is the last
Windows client operating systems
to support Itanium. Windows Server
line continued to support this
platform until Windows Server
2012; Windows Server 2008 R2 is
the last Windows operating system
to support Itanium architecture.
On April 25, 2005, Microsoft
released Windows XP Professional
x64 Edition and Windows Server
2003 x64 Editions to support the
x86-64 (or simply x64), the eighth
generation of x86 architecture.
Windows Vista was the first client
version of Windows NT to be
released simultaneously in IA-32
and x64 editions. x64 is still
supported.
An edition of Windows 8 known as
Windows RT was specifically
created for computers with ARM
architecture.
Windows CE
Main articles: Windows CE and
Windows Phone
The latest current version of
Windows CE, Windows Embedded
Compact 7, displaying a concept
media player UI.
Windows CE (officially known as
Windows Embedded Compact ), is an
edition of Windows that runs on
minimalistic computers , like
satellite navigation systems and
some mobile phones. Windows
Embedded Compact is based on its
own dedicated kernel, dubbed
Windows CE kernel. Microsoft
licenses Windows CE to OEMs and
device makers. The OEMs and
device makers can modify and
create their own user interfaces and
experiences, while Windows CE
provides the technical foundation to
do so.
Windows CE was used in the
Dreamcast along with Sega's own
proprietary OS for the console.
Windows CE was the core from
which Windows Mobile was
derived. Its successor, Windows
Phone 7 , was based on components
from both Windows CE 6.0 R3 and
Windows CE 7.0 . Windows Phone 8
however, is based on the same NT-
kernel as Windows 8.
Windows Embedded Compact is not
to be confused with Windows XP
Embedded or Windows NT 4.0
Embedded, modular editions of
Windows based on Windows NT
kernel.
Xbox OS
Xbox OS is an unofficial name given
to the version of Windows that runs
on the Xbox One. [41] It is a more
specific implementation with an
emphasis on virtualization (using
Hyper-V ) as it is three operating
systems running at once, consisting
of the core operating system, a
second implemented for games and
a more Windows-like environment
for applications. [42]
