3. Microsoft Windows is a series of software operating systems and
graphical user interfaces produced by Microsoft. Microsoft first
introduced an operating environment named Windows in
November 1985 as an add-on to MS-DOS in response to the
growing interest in graphical user interfaces (GUIs).[2] Microsoft
Windows came to dominate the world's personal computer
market, overtaking Mac OS, which had been introduced
previously. As of October 2009, Windows had approximately 91%
of the market share of the client operating systems for usage
on the Internet.[3][4][5] The most recent client version of
Windows is Windows 7; the most recent server version is
Windows Server 2008 R2; the most recent mobile OS version is
Windows Mobile 6.5

5. EARLY VERSIOSN

6. Windows 1.0 did not allow overlapping windows, due
to Apple Computer owning this feature Instead all
windows were tiled. Only dialog boxes could appear
over other windows.
Windows 2.0 was released in October 1987 and
featured several improvements to the user interface
and memory management.[6] Windows 2.0 allowed
application windows to overlap each other and also
introduced more sophisticated keyboard-shortcuts. It
could also make use of expanded memory.
Windows 2.1 was released in two different flavors:
Windows/386 employed the 386 virtual 8086 mode to
multitask several DOS programs, and the paged
memory model to emulate expanded memory using
available extended memory. Windows/286 (which,
despite its name, would run on the 8086) still ran in
real mode, but could make use of the high

7. Windows 3.0 and 3.1

8. Windows 3.0 (1990) and Windows 3.1
(1992) improved the design, mostly
because of virtual memory and loadable
virtual device drivers (VxDs) which
allowed them to share arbitrary devices
between multitasked DOS
windows.[citation needed] Also, Windows
applications could now run in protected
mode (when Windows was running in
Standard or 386 Enhanced Mode), which
gave them access to several megabytes
of memory and removed the obligation
to participate in the software virtual
memory scheme

9. Windows 95, 98, and Me

10. Windows 95 was released in August 1995,
featuring a new user interface, support for
long file names of up to 255 characters, and
the ability to automatically detect and
configure installed hardware (plug and
play). It could natively run 32-bit
applications, and featured several
technological improvements that increased
its stability over Windows 3.1. There were
several OEM Service Releases (OSR) of
Windows 95, each of which was roughly
equivalent to a service pack.
Microsoft's next release was Windows 98 in
June 1998. Microsoft released a second
version of Windows 98 in May 1999, named
Windows 98 Second Edition (often shortened
to Windows 98 SE).

11. Windows NT family
The NT family of Windows systems
was fashioned and marketed for
higher reliability business use. The
first release was NT 3.1
(1993), numbered "3.1" to match
the consumer Windows
version, which was followed by NT
3.5 (1994), NT 3.51 (1995), NT 4.0
(1996), and Windows 2000 (2000).
2000 is the last NT-based Windows
release which does not include
Microsoft Product Activation. NT 4.0
was the first in this line to
implement the "Windows 95" user
interface (and the first to include
Windows 95’s built-in 32-bit
runtimes).

12. WINDOW VISTA

13. Windows Vista is an operating system
expressed in several variations developed
by Microsoft for use on personal
computers, including home and business
desktops, laptops, tablet PCs, and media
center PCs. Prior to its announcement on
July 22, 2005, Windows Vista was known by
its codename "Longhorn."[4] Development
was completed on November 8, 2006; over
the following three months it was released
in stages to computer hardware and
software manufacturers, business
customers, and retail channels. On January
30, 2007, it was released worldwide,[5] and
was made available for purchase and
download from Microsoft's website.[6] The
release of Windows Vista came more than
five years after the introduction of its
predecessor, Windows XP, the longest time
span between successive releases of
Microsoft Windows desktop operating
systems. It was succeeded by Windows 7
which was released to manufacturing on
July 22, 2009, and for the general public on
October 22, 2009.

14. WINDOW7
Windows 7 is a version of Microsoft Windows, a
series of operating systems produced by Microsoft
for use on personal computers, including home and
business desktops, laptops, netbooks, tablet
PCs, and media center PCs.[4] Windows 7 was
released to manufacturing on July 22, 2009,[5] and
reached general retail availability on October
22, 2009,[6] less than three years after the release
of its predecessor, Windows Vista. Windows 7's
server counterpart, Windows Server 2008 R2, was
released at the same time. Windows 7 will be
succeeded by Windows 8, which has no release
date as of yet.

15. ADVANCEMENTS OF OPERATING SYSTEM
Some of the most popular and
functional types of window treatments
on the market today are window shades
(such as cellular shades, sheer shades
and roller shades) and blinds (like
bamboo blinds, vertical blinds and mini
blinds). These versatile window
treatments allow you to regulate the
amount of light that enters any room in
a variety of ways – by adjusting the
slats or raising the shade up and down.
Window treatments can also help
prevent fabrics and rugs from being
faded by ultraviolet rays.
Certainly, many improvements have
been made in the quality and design of
window treatments in recent years.

16. Let’s take a brief look at some of the
advancements in today’s window treatment options
that can add spark, color and texture to any room
and serve as a reflection of your personal style.
Draperies now come with a wide variety of options
in rod styles including tab tops, tie tops, many
types of pleats, grommets, rod pockets (large or
small), flouncy tops, or plain rings.
Valances can be
gathered, pleated, shirred, swagged, bundled, for
mal, casual, scalloped, lace, or flat to create your
own unique style.
Fabric Shades are available in flat Roman
style, balloon, Austrian, bottom
arched, pleated, and flat panels and can be made
of sheer or coordinating fabrics.
Metal Mini Blinds offer advancements in slat weight
and size, specialty finishes, privacy options, header
choices, cloth tapes, and hundreds of colors.
