Microsoft WindowsMicrosoft 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

EARLY VERSIOSN

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

Windows 3.0 and 3.1

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

Windows 95, 98, and Me

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).

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).

WINDOW VISTA

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.

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.

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.

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, formal, 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.
