HISTORY OF WINDOWS

            A history of Windows

Hghlights from the first 25 years

1975–1981: Microsoft boots up

Getting started: Microsoft co-founders Paul Allen (left) and Bill Gates

It’s the 1970s. At work, we rely on typewriters. If we need to copy a document, we likely use a mimeograph or carbon paper. Few have heard of microcomputers, but two young computer enthusiasts, Bill Gates and Paul Allen, see that personal computing is a path to the future.

In 1975, Gates and Allen form a partnership called Microsoft. Like most start-ups, Microsoft begins small, but has a huge vision—a computer on every desktop and in every home. During the next years, Microsoft begins to change the ways we work.

The dawn of MS‑DOS

In June 1980, Gates and Allen hire Gates’ former Harvard classmate Steve Ballmer to help run the company. The next month, IBM approaches Microsoft about a project code-named "Chess." In response, Microsoft focuses on a new operating system—the software that manages, or runs, the computer hardware and also serves to bridge the gap between the computer hardware and programs, such as a word processor. It’s the foundation on which computer programs can run. They name their new operating system "MS‑DOS."

When the IBM PC running MS‑DOS ships in 1981, it introduces a whole new language to the general public. Typing “C:” and various cryptic commands gradually becomes part of daily work. People discover the backslash (\) key.

MS‑DOS is effective, but also proves difficult to understand for many people. There has to be a better way to build an operating system.

Geek trivia: MS‑DOS stands for Microsoft Disk Operating System.

1982–1985: Introducing Windows 1.0

Microsoft works on the first version of a new operating system. Interface Manager is the code name and is considered as the final name, but Windows prevails because it best describes the boxes or computing “windows” that are fundamental to the new system. Windows is announced in 1983, but it takes a while to develop. Skeptics call it “vaporware.”

The fully-packaged Windows 1.0

On November 20, 1985, two years after the initial announcement, Microsoft ships Windows 1.0. Now, rather than typing MS‑DOS commands, you just move a mouse to point and click your way through screens, or “windows.” Bill Gates says, “It is unique software designed for the serious PC user…”

There are drop-down menus, scroll bars, icons, and dialog boxes that make programs easier to learn and use. You're able to switch among several programs without having to quit and restart each one. Windows 1.0 ships with several programs, including MS‑DOS file management, Paint, Windows Writer, Notepad, Calculator, and a calendar, card file, and clock to help you manage day-to-day activities. There’s even a game—Reversi.

Geek trivia: Remember floppy disks and kilobytes? Windows 1.0 requires a minimum of 256 kilobytes (KB), two double-sided floppy disk drives, and a graphics adapter card. A hard disk and 512 KB memory is recommended for running multiple programs or when using DOS 3.0 or higher.

1987–1992: Windows 2.0–2.11—More windows, more speed

On December 9, 1987 Microsoft releases Windows 2.0 with desktop icons and expanded memory. With improved graphics support, you can now overlap windows, control the screen layout, and use keyboard shortcuts to speed up your work. Some software developers write their first Windows–based programs for this release.

Windows 2.0

Windows 2.0 is designed for the Intel 286 processor. When the Intel 386 processor is released, Windows/386 soon follows to take advantage of its extended memory capabilities. Subsequent Windows releases continue to improve the speed, reliability, and usability of the PC.

In 1988, Microsoft becomes the world’s largest PC software company based on sales. Computers are starting to become a part of daily life for some office workers.

Geek trivia: Control Panel makes its first appearance in Windows 2.0.

1990–1994: Windows 3.0–Windows NT—Getting the graphics

On May 22, 1990, Microsoft announces Windows 3.0, followed shortly by Windows 3.1 in 1992. Taken together, they sell 10 million copies in their first 2 years, making this the most widely used Windows operating system yet. The scale of this success causes Microsoft to revise earlier plans. Virtual Memory improves visual graphics. In 1990 Windows starts to look like the versions to come.

Windows now has significantly better performance, advanced graphics with 16 colors, and improved icons. A new wave of 386 PCs helps drive the popularity of Windows 3.0. With full support for the Intel 386 processor, programs run noticeably faster. Program Manager, File Manager, and Print Manager arrive in Windows 3.0.

Bill Gates shows the newly-released Windows 3.0

Windows software is installed with floppy discs bought in large boxes with heavy instruction manuals.

The popularity of Windows 3.0 grows with the release of a new Windows software development kit (SDK), which helps software developers focus more on writing programs and less on writing device drivers.

Windows is increasingly used at work and home and now includes games like Solitaire, Hearts, and Minesweeper. An advertisement: “Now you can use the incredible power of Windows 3.0 to goof off.”

Windows for Workgroups 3.11 adds peer-to-peer workgroup and domain networking support and, for the first time, PCs become an integral part of the emerging client/server computing evolution.

Windows NT

When Windows NT releases on July 27, 1993, Microsoft meets an important milestone: the completion of a project begun in the late 1980s to build an advanced new operating system from scratch. "Windows NT represents nothing less than a fundamental change in the way that companies can address their business computing requirements," Bill Gates says at its release.

Unlike Windows 3.1, however, Windows NT 3.1 is a 32-bit operating system, which makes it a strategic business platform that supports high-end engineering and scientific programs.

Geek trivia: The group that develops Windows NT was originally called the "Portable Systems" team.

1995–2001: Windows 95—the PC comes of age (and don't forget the Internet)

On August 24, 1995, Microsoft releases Windows 95, selling a record-setting 7 million copies in the first five weeks. It’s the most publicized launch Microsoft has ever taken on. Television commercials feature the Rolling Stones singing "Start Me Up" over images of the new Start button. The press release simply begins: “It’s here.”

Launch day: Bill Gates introduces Windows 95

This is the era of fax/modems, e‑mail, the new online world, and dazzling multimedia games and educational software. Windows 95 has built-in Internet support, dial-up networking, and new Plug and Play capabilities that make it easy to install hardware and software. The 32-bit operating system also offers enhanced multimedia capabilities, more powerful features for mobile computing, and integrated networking.

At the time of the Windows 95 release, the previous Windows and MS‑DOS operating systems are running on about 80 percent of the world’s PCs. Windows 95 is the upgrade to these operating systems. To run Windows 95, you need a PC with a 386DX or higher processor (486 recommended) and at least 4 MB of RAM (8 MB of RAM recommended). Upgrade versions are available for both floppy disk and CD-ROM formats. It’s available in 12 languages.

Windows 95 features the first appearance of the Start menu, taskbar, and minimize, maximize, and close buttons on each window.

Catching the Internet wave

In the early 1990s, tech insiders are talking about the Internet—a network of networks that has the power to connect computers all over the world. In 1995, Bill Gates delivers a memo titled “The Internet Tidal Wave,” and declares the Internet as “the most important development since the advent of the PC.”

In the summer of 1995, the first version of Internet Explorer is released. The browser joins those already vying for space on the World Wide Web.

Geek trivia: In 1996, Microsoft releases Flight Simulator for Windows 95—the first time in its 14-year history that it’s available for Windows.

1998–2000: Windows 98, Windows 2000, Windows Me

Windows 98

Released on June 25, 1998, Windows 98 is the first version of Windows designed specifically for consumers. PCs are common at work and home, and Internet cafes where you can get online are popping up. Windows 98 is described as an operating system that “Works Better, Plays Better.”

With Windows 98, you can find information more easily on your PC as well as the Internet. Other improvements include the ability to open and close programs more quickly, and support for reading DVD discs and universal serial bus (USB) devices. Another first appearance is the Quick Launch bar, which lets you run programs without having to browse the Start menu or look for them on the desktop.

Geek trivia: Windows 98 is the last version based on MS‑DOS.

Windows 98

Windows Me

Designed for home computer use, Windows Me offers numerous music, video, and home networking enhancements and reliability improvements compared to previous versions.

First appearances: System Restore, a feature that can roll back your PC software configuration to a date or time before a problem occurred. Movie Maker provides users with the tools to digitally edit, save, and share home videos. And with Microsoft Windows Media Player 7 technologies, you can find, organize, and play digital media.

Geek trivia: Technically speaking, Windows Me was the last Microsoft operating system to be based on the Windows 95 code base. Microsoft announced that all future operating system products would be based on the Windows NT and Windows 2000 kernel.

Windows 2000 Professional

Windows 2000 Professional

More than just the upgrade to Windows NT Workstation 4.0, Windows 2000 Professional is designed to replace Windows 95, Windows 98, and Windows NT Workstation 4.0 on all business desktops and laptops. Built on top of the proven Windows NT Workstation 4.0 code base, Windows 2000 adds major improvements in reliability, ease of use, Internet compatibility, and support for mobile computing.

Among other improvements, Windows 2000 Professional simplifies hardware installation by adding support for a wide variety of new Plug and Play hardware, including advanced networking and wireless products, USB devices, IEEE 1394 devices, and infrared devices.

Geek trivia: The nightly stress test performed on Windows 2000 during development is the equivalent of three months of run time on up to 1,500 computers.

2001–2005: Windows XP—Stable, usable, and fast

On October 25, 2001, Windows XP is released with a redesigned look and feel that's centered on usability and a unified Help and Support services center. It’s available in 25 languages. From the mid-1970s until the release of Windows XP, about 1 billion PCs have been shipped worldwide.

For Microsoft, Windows XP will become one of its best-selling products in the coming years. It’s both fast and stable. Navigating the Start menu, taskbar, and Control Panel are more intuitive. Awareness of computer viruses and hackers increases, but fears are to a certain extent calmed by the online delivery of security updates. Consumers begin to understand warnings about suspicious attachments and viruses. There’s more emphasis on Help and Support.

Ship it: Windows XP Professional rolls to retail stores

Windows XP Home Edition offers a clean, simplified visual design that makes frequently used features more accessible. Designed for home use, Windows XP offers such enhancements as the Network Setup Wizard, Windows Media Player, Windows Movie Maker, and enhanced digital photo capabilities.

Windows XP Professional brings the solid foundation of Windows 2000 to the PC desktop, enhancing reliability, security, and performance. With a fresh visual design, Windows XP Professional includes features for business and advanced home computing, including remote desktop support, an encrypting file system, and system restore and advanced networking features. Key enhancements for mobile users include wireless 802.1x networking support, Windows Messenger, and Remote Assistance.

Windows XP has several editions during these years:

·         Windows XP 64-bit Edition (2001) is the first Microsoft operating system for 64-bit processors designed for working with large amounts of memory and projects such as movie special effects, 3D animations, engineering, and scientific programs.

·         Windows XP Media Center Edition (2002) is made for home computing and entertainment. You can browse the Internet, watch live television, enjoy digital music and video collections, and watch DVDs.

·         Windows XP Tablet PC Edition (2002) realizes the vision of pen-based computing. Tablet PCs include a digital pen for handwriting recognition and you can use the mouse or keyboard, too.

Geek trivia: Windows XP is compiled from 45 million lines of code.

2006–2008: Windows Vista—Smart on security

Windows Vista is released in 2006 with the strongest security system yet. User Account Control helps prevent potentially harmful software from making changes to your computer. In Windows Vista Ultimate, BitLocker Drive Encryption provides better data protection for your computer, as laptop sales and security needs increase. Windows Vista also features enhancements to Windows Media Player as more and more people come to see their PCs as central locations for digital media. Here you can watch television, view and send photographs, and edit videos.

Windows Vista Ultimate

Design plays a big role in Windows Vista, and features such as the taskbar and the borders around windows get a brand new look. Search gets new emphasis and helps people find files on their PCs faster. Windows Vista introduces new editions that each have a different mix of features. It's available in 35 languages. The redesigned Start button makes its first appearance in Windows Vista.

Geek trivia: More than 1.5 million devices are compatible with Windows Vista at launch.

2009: Windows 7

Windows 7 was built for the wireless world that arose in the late 2000s. By the time it was released, laptops were outselling desktops, and it had become common to connect to public wireless hotspots in coffee shops and private networks in the home.

Windows 7 included new ways to work with windows—like Snap, Peek, and Shake—which both improved functionality and made the interface more fun to use. It also marked the debut of Windows Touch, which let touchscreen users browse the web, flip through photos, and open files and folders.

Geek trivia: Power users will notice that Windows 8 has made the detection and correction of file system errors both more transparent and less intrusive.

Improvements to the Windows 7 taskbar include live thumbnail previews

Geek trivia: Windows 7 was evaluated by 8 million beta testers worldwide before it was released.

2012: Windows 8

Windows 8 is Windows reimagined from the chipset to the user experience. It functions as both a tablet for entertainment and a full-featured PC for getting things done. It introduces a totally new interface that works smoothly for both touch and mouse and keyboard. Windows 8 also includes enhancements of the familiar Windows desktop, with a new taskbar and streamlined file management.

Windows 8 features a Start screen with tiles that connect to people, files, apps, and websites. Apps are front and center, with access to a new place to get apps—the Windows Store—built right in to the Start screen.

Along with Windows 8, Microsoft also launched Windows RT, which runs on some tablets and PCs. Windows RT is designed for sleek devices and long battery life, and exclusively runs apps from the Windows Store. It also comes with a built-in version of Office that's optimized for touchscreens.

AN ADVANCED PERSISTENT THREAT(APT)

An advanced persistent threat (APT) is a network attack in which an unauthorized person gains access to a network and stays there undetected for a long period of time. The intention of an APT attack is to steal data rather than to cause damage to the network or organization. APT attacks target organizations in sectors with high-value information, such as national defense, manufacturing and the financial industry.

In a simple attack, the intruder tries to get in and out as quickly as possible in order to avoid detection by the network's intrusion detection system (IDS). In an APT attack, however, the goal is not to get in and out but to achieve ongoing access. To maintain access without discovery, the intruder must continuously rewrite code and employ sophisticated evasion techniques. Some APTs are so complex that they require a full time administrator.

An APT attacker often uses spear fishing, a type of social engineering, to gain access to the network through legitimate means. Once access has been achieved, the attacker establishes a back door.

The next step is to gather valid user credentials (especially administrative ones) and move laterally across the network, installing more back doors. The back doors allow the attacker to install bogus utilities and create a "ghost infrastructure" for distributing malware that remains hidden in plain sight.

Although APT attacks are difficult to identify, the theft of data can never be completely invisible. Detecting anomalies in outbound data is perhaps the best way for an administrator to discover that his network has been the target of an APT attack.

distributed antenna system (DAS)

A distributed antenna system (DAS) is a way to deal with isolated spots of poor coverage inside a large building by installing a network of relatively small antennas throughout the building to serve as repeaters.

The antennas are physically connected to a central controller which is connected to the wireless carrier network’s base station. Because distributed antenna systems operate on RF spectrum licensed to wireless carriers, an enterprise cannot undertake a DAS deployment on its own without involving at least one carrier. 

Distributed antenna systems can be passive or active. A passive DAS grabs cellphone signals from antennas on the roof and runs them through leaky feeder cables throughout the building. In this approach, the signal leakage distributes the signal. In an active system, the signal is passed from roof antennas through fiber cables. Along the way, systems boost and amplify signals as needed.

Deployment is the most expensive stage of a DAS project because installing antennas and stringing fiber optical or coaxial cable between antenna modules and the controller are all very labor intensive processes. Generally, the carrier bears the costs of installing the system as well as maintenance expenses and many times, the carrier will only agree to take on these costs if the deployment fits within their network plans, covers a large number of subscribers or fills an significant gap in service. To keep the cost down, a DAS may be shared by multiple carriers.

Distributed antenna systems are transparent to mobile devices, providing both voice and data services to mobile devices just like any tower on a cellular network. Densely populated indoor spaces such as shopping malls, medical centers and high-rise buildings are all good candidates for DAS deployments.

Over the past five years, wireless data traffic has increased more than 20,000 percent on AT&T’s wireless network alone. People are no longer only accessing the Internet at home or in the office, they are doing it wherever they are from their mobile device.

AT&T network engineers are helping enable this shift in Internet usage habits by putting in place new technologies, such as Distributed Antenna Systems (DAS). A DAS network consists of many antennas tuned to precisely match the areas of a building or venue where boosted service is needed. AT&T DAS helps address the exponential network traffic growth at large venues and other hard to serve areas, such as sporting and entertainment venues, hospitals, college campuses, airports, hotels, conference centers and more.

DAS helps boost mobile broadband coverage, improve reliability in heavily trafficked areas and enhance network capacity, alleviating pressure on wireless networks when thousands of people in close proximity are actively using their mobile devices simultaneously. DAS is seamless and invisible for customers, but the results are easy to see. Data and voice capacity more than doubled at the pro sports venues that installed AT&T DAS in 2011.

Behind the scenes making this innovation possible are AT&T engineers implementing a variety of strategies to meet the unique needs of each venue or building owner.

Chad Townes, Vice President of AT&T’s Antenna Solutions Group (ASG), oversees all of the company’s DAS installations. As Towne’s group began to notice smartphone trends and usage patterns skyrocket, increased emphasis was placed on getting ahead of the curve by installing DAS in a variety of locations, including sports venues. As Vice President of AT&T’s ASG, Townes is responsible for the end to end deployment of AT&T wireless infrastructure delivered via DAS. This includes the Sales, Negotiations, RF Engineering, Design, and Construction of both in building and outdoor DAS applications throughout AT&T’s network.

Bill Schlough, Senior Vice President and Chief Information Officer for the San Francisco Giants, sensed mobile data demand was on a sharp rise as early as 2009, which led his charge to create an extremely tech-friendly atmosphere at AT&T Park, home of the San Francisco Giants. Leading up to the 2010 baseball season, Schlough and his team already had an AT&T Wi-Fi system in place, but worked with AT&T to install a DAS to combat the data crunch coming from the nimble hands of smartphone-wielding fans at the ballpark.

Since the installation, the mobile experience at the ballpark has been night and day according to Schlough. While many fans might not know that DAS or Wi-Fi are powering their network at Giants games, they do notice the reliable and consistent mobile Internet connection they have come to trust and rely on to enhance the experience at games.

AT&T is a leader in the DAS space and annually installs hundreds of systems across the country. However, as new technology and opportunities present themselves, AT&T’s ASG will continue to adapt and modify the way its DAS perform and operate in order to provide the best possible end-user experience:

• Faster Speeds. As DAS deployments continue nationwide at sporting stadiums, campuses, airports and other venues, AT&T is beginning to upgrade and build new DAS with ultra-fast 4G LTE speeds.
• DAS on Wheels (DOW). At the recent major political convention in Charlotte, N.C. AT&T rolled out its first ever DAS on Wheels. The mobile DAS consisted of a mobile head end situated in an AT&T truck and portable antennas located throughout a major Charlotte Arena. AT&T is currently exploring future opportunities to deploy DOW.
