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 under the
name "Windows", but Windows 1.0 was not
released until November 1985.

 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.
 Included components include Calculator, Calendar,
Cardfile, Clipboard viewer, Clock, Control Panel,
Notepad, Paint, Reversi, 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 .
Windows 2.03 changed the OS from tiled windows
to overlapping windows. Windows 2.0 also
introduced more sophisticated keyboard shortcuts
and could make use of expanded memory.

Windows 3.0, released in 1990, improved the design,
mostly because of virtual memory and loadable virtual
device drivers that allow Windows to share arbitrary
devices between multi-tasked DOS applications.
Windows 3.0 is the first Microsoft Windows version to
achieve broad commercial success, selling 2 million
copies in the first six months.
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

Windows 9X – Windows 95, Windows
98, and Windows ME

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, pre-emptive multitasking,
long file names of up to 255 characters, and
provided increased stability over its predecessors.

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

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
Windows ‘NT’ Family (2000)

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.
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. It was followed in December 2005 by Windows Server
2003 R2

Windows Vista
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.
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

WINDOWS 7
Our college currently uses the Windows 7 operating system.
Among Windows 7's new features are advances in touch
and handwriting recognition ,support for virtual hard
disks, improved performance on multi-core
processors, improved boot performance, DirectAccess,
and kernel improvements.
Many new items have been added to the Control Panel,
including Clear Type Text Tuner Display Color Calibration
Wizard ,Gadgets, Recovery, Troubleshooting, Workspaces
Center , Location and Other Sensors, Credential Manager,
Biometric Devices, System Icons, and Display.

 The taskbar has seen the biggest visual changes,
where the old Quick Launch toolbar has been replaced
with the ability to pin applications to the taskbar.
Buttons for pinned applications are integrated with
the task buttons. These buttons also enable the Jump
Lists feature to allow easy access to common tasks.
 The revamped taskbar also allows the reordering of
taskbar buttons. To the far right of the system clock is
a small rectangular button that serves as the Show
desktop icon. This button is part of the new feature in
Windows 7 called Aero Peek. Hovering over this
button makes all visible windows transparent for a
quick look at the desktop.

Reception
Reviews of Windows 7 have been generally positive, noting
the increased usability and functionality when compared to
its predecessor, Windows Vista. CNET gave Windows 7
Home Premium a rating of 4.5 out of 5 stars, stating that it
"is more than what Vista should have been, [and] it's where
Microsoft needed to go". PC Magazine rated it a 4 out of 5
saying that Windows 7 is a "big improvement" over
Windows Vista, with fewer compatibility problems, a
retooled taskbar, simpler home networking and faster start-
up.

Windows 8, the successor to Windows 7, was released
generally on October 28, 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.
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, the
return of the traditional Start Button, and many other
revisions.
