What is “Windows 7″ ?

May 26, 2015

Windows 7 – A personal computer operating system developed by Microsoft. It is a part of Windows NT family of operating systems. Development of Windows 7 started as early as 2006 under the codename “Blackcomb.” Windows 7 was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009, 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 was primarily intended to be an incremental upgrade to the operating system, intending to address Windows Vista’s critical reception (such as performance improvements), while maintaining hardware and software compatibility. Windows 7 continued improvements on Windows Aero (the user interface introduced in Windows Vista) with the addition of a redesigned taskbar that allows applications to be “pinned” to it, and new window management features. Other new features were added to the operating system, including libraries, the new file sharing system HomeGroup, and support for multitouch input. A new “Action Center” interface was also added to provide an overview of system security and maintenance information, and tweaks were made to the User Account Control system to make it less intrusive. Windows 7 also shipped with updated versions of several stock applications, including Internet Explorer, Windows Media Player, and Windows Media Center.

In contrast to Vista, Windows 7 was generally praised by critics, who considered the operating system to be a major improvement over its predecessor due to its increased performance, its more intuitive interface (with particular praise devoted to the new taskbar), fewer User Account Control popups, and other improvements made across the platform. Windows 7 was a major success for Microsoft; even prior to its official release, pre-order sales for 7 on the online retailer Amazon.com had surpassed the previous records. In just six months, over 100 million copies had been sold worldwide, increasing to over 630 million licenses by July 2012, and a market share of 50.06% as of May 2014 according to Net Applications, making it the most widely used version of Windows.

What is “Windows Vista” ?

May 19, 2015

Windows Vista – Codenamed Longhorn, is an operating system by Microsoft for use on personal computers, including home and business desktops, laptops, tablet PCs, and media center PCs. Development was completed on November 8, 2006, and 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 and was made available for purchase and download from Microsoft’s website. 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 released worldwide for retail on October 22, 2009.

New features of Windows Vista include an updated graphical user interface and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display sub-systems, and new multimedia tools including Windows DVD Maker. Vista aimed to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.

Microsoft’s primary stated objective with Windows Vista was to improve the state of security in the Windows operating system. One common criticism of Windows XP and its predecessors was their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide “Trustworthy Computing initiative”, which aimed to incorporate security into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.

While these new features and security improvements have garnered positive reviews, Vista has also been the target of much criticism and negative press. Criticism of Windows Vista has targeted its high system requirements, its more restrictive licensing terms, the inclusion of a number of new digital rights management technologies aimed at restricting the copying of protected digital media, lack of compatibility with some pre-Vista hardware and software, and the number of authorization prompts for User Account Control. As a result of these and other issues, Windows Vista had seen initial adoption and satisfaction rates lower than Windows XP. However, with an estimated 330 million Internet users as of January 2009, it had been announced that Vista usage had surpassed Microsoft’s pre-launch two-year-out expectations of achieving 200 million users. At the release of Windows 7 (October 2009), Windows Vista (with approximately 400 million Internet users) was the second most widely used operating system on the Internet with an approximately 19% market share, the most widely used being Windows XP with an approximately 63% market share. As of May 2010, Windows Vista’s market share had an estimated range from 15% to 26%. On October 22, 2010, Microsoft ceased sales of retail copies of Windows Vista, and the OEM sales for Vista ceased a year later. As of March 2015, Vista market share is at 2.11%.

What is “Windows XP” ?

May 12, 2015

Windows XP – Codenamed Whistler, is a personal computer operating system produced by Microsoft as part of the Windows NT family of operating systems. The operating system was released to manufacturing on August 24, 2001, and generally released for retail sale on October 25, 2001.

Development of XP began in the late 1990’s as “Neptune”, an operating system built on the Windows NT kernel which was intended specifically for mainstream consumer use—an updated version of Windows 2000 was also originally planned for the business market. However, in January 2000, both projects were shelved in favor of a single OS codenamed “Whistler”, which would serve as a single OS platform for both consumer and business markets. Windows XP was a major advance from theMS-DOS based versions of Windows in security, stability and efficiency due to its use of Windows NT underpinnings. It introduced a significantly redesigned graphical user interface and was the first version of Windows to use product activation in an effort to reduce software piracy.

Upon its release Windows XP received generally positive reviews, with critics noting increased performance (especially in comparison to Windows ME), a more intuitive user interface, improved hardware support, and its expanded multimedia capabilities. Despite some initial concerns over the new licensing model and product activation system, Windows XP eventually proved to be popular and widely used. It is estimated that at least 400 million copies of Windows XP were sold globally within its first five years of availability, and at least one billion copies were sold by April 2014.

Windows XP remained popular even after the release of newer versions, particularly due to the poorly received release of its successor Windows Vista. Vista’s 2009 successor, Windows 7, only overtook XP in total market share at the end of 2011.

Sales of Windows XP licenses to original equipment manufacturers (OEMs) ceased on June 30, 2008, but continued for netbooks until October 2010. Extended support for Windows XP ended on April 8, 2014, after which the operating system ceased receiving further support or security updates to most users.

What is “Windows 95″ ?

April 28, 2015

Windows 95 – Codenamed Chicago, is a consumer-oriented operating system developed by Microsoft. It was released on August 24, 1995, and was a significant progression from the company’s previous Windows products.

Windows 95 integrated Microsoft’s formerly separate MS-DOS and Windows products. It featured significant improvements over its predecessor, Windows 3.1, most notably in the graphical user interface (GUI) and in its relatively simplified “plug-n-play” features. There were also major changes made at lower levels of the operating system, such as moving from a mainly 16-bit architecture to a pre-emptively multitasked 32-bit architecture.

Accompanied by an extensive marketing campaign, Windows 95 was a major success in the marketplace at launch and shortly became the most popular desktop operating system. It also introduced numerous functions and features that were featured in later Windows versions, such as the taskbar, the ‘Start’ button, and the way the user navigates. It was also suggested that Windows 95 had an effect of driving other major players (including OS/2) out of business, something which would later be used in court against Microsoft.

Three years after its introduction, Windows 95 was succeeded by Windows 98. Support for Windows 95 ended on December 31, 2001.
