Windows 7 launched

Windows 7 is the latest version of Microsoft Windows produced for use on home and business desktops, laptops, netbooks, tablet personal computers and media center of personal computers. Windows 7  was released to manufacturing on July 22, 2009. General retail availability was announced on October 22, 2009, less than three years after the release of its predecessor, Windows Vista. 

Unlike Windows Vista, which introduced a large number of new features, Windows 7 is intended to be a more user focused, helpful upgrade to the Windows line. As a result Windows 7 is fully compatible with applications and hardware with which Windows Vista is already compatible. Some applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo, are not involved in Windows 7. Several of them are instead offered separately as a part of the free Windows Live Essential Suite.


Earlier in 2007 Bill Gates in an interview with Newsweek, insinuated that this version of Windows would “be more user-centric”. Later he added that Windows 7 would also focus on performance improvements. Steven Sinofsky, the new president of the Windows division at Microsoft, responsible for the Windows, Windows Live, and Internet Explorer, afterward expanded on this point in the Engineering Windows 7 blog. He explicated that the company was using a variety of new tracing tools to measure the performance of many areas of the operating systém. The tools help locate inefficient code paths and prevent decrease of performance effectiveness.

The Senior Vice President Bill Veghte stated that Windows Vista users migrating to Windows 7 would not find the kind of device compatibility issues they met migrating from Windows XP. As early as in October 2008, the Microsoft Chief Executive Steve Ballmer confirmed compatibility between Vista and Windows 7, pointing out that Windows 7 would be a refined version of Windows Vista.

New and changed features

Windows 7 includes a number of new features, such as advances in touch and handwriting recognition, support for virtual hard disks, improved performance on multi-core processors, improved boot  performance, Direct Access, and kernel improvements. Windows 7 adds support for systems using multiple heterogeneous graphics cards from different vendors, a new version of Windows Media Center, the XML Paper Specification (XPS) Essentials Pack. Windows Power Shell, and a redesigned Calculator with multiline capabilities. Many new items have been added to the Control Panel, such as the Clear Type Text Tuner, Biometric Devices, System Icons, Display, etc. Windows 7 also supports Mac-like Raw image viewing plus full-size viewing and slideshows in the Windows Photo Viewer and Window Media Center.

Windows 7 includes 13 additional sound schemes, titled Afternoon, Calligraphy, Characters, Cityscape, Delta, Festival, Garden, Heritage, Landscape, Quirky, Raga, Savanna, and Sonata. A new version of a Windows Virtual PC Beta is available for Windows 7 Professional, Enterprise, and Ultimate editions. It allows multiple Windows environments, including Windows XP Mode, to run on the same machine, requiring the use of Intel Virtualisation Technology for x86 (Intel VT-x) or AMD Virtualisation (AMD-V). Windows XP Mode runs Windows XP in a virtual machine and redirects displayed applications running in Windows XP to the Windows 7 desktop. Furthermore, Windows 7 supports the mounting of a virtual hard disk (VHD) as a normal data storage, and the bootloader delivered with Windows 7 can boot the Windows system from a VHD. The Remote Desktop Protokol (RDP) of Windows 7 is also enhanced to support real-time multimedia applications including video playback and 3D games.

The taskbar has seen the biggest visual changes, where the Quick Launch toolbar has been replaced with pinning applications to the taskbar. Buttons for pinned applications are integrated with the task buttons. The revamped taskbar also allows the reordering of taskbar buttons. To the far right of the system clock there is a small rectangular button that serves as the Show desktop icon. This button is a 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. In touch-enabled displays such as touch screens, tablet PCs, etc., this button is slightly wider to accommodate being pressed with a finger. Clicking this button minimizes all windows, and clicking it a second time restores them. Additionally, there is a feature named Aero Snap, which automatically maximizes a window when it is dragged to either the top or left/right edges of the screen. This also allows users to snap documents or files on either side of the screen to compare them.

Windows 7 taskbar includes a new networking API – Application Programming Interface for developers. It supports building Simple Object Access Protocol based (SOAP-based) web services in machine code, adds new features to shorten application installing time, reduced User Account Control (UAC) prompts, simplified development of installation packages, and improved worldwide support through a new Extended Linguistic Services API. As early as in 2008 Microsoft announced that colour depths of 30-bit and 48-bit would be supported in Windows 7. The video modes supported in Windows 7 are 16-bit  class=”hiddenSpellError” pre=”16-bit “>sRGB (standard Red Green Blue colour space), 24-bit sRGB, 30-bit sRGB, 30-bit with extended colour gamut sRGB, and 48-bit scRGB. Microsoft is also implementing better support for solid-state drives, so Windows 7 will be able to identify a solid-state drive uniquely. Microsoft is also planning to support USB 3.0 in a subsequent patch, although support would not be included in the initial release because of delays in the finalization of the standard.

Users will also be qualified to disable more Windows components than it was possible in Windows Vista. New additions to this list of components include Internet Explorer, Windows Media Player, Windows Media Center, Windows Search , and the Windows Gadget Platform.

“The launch of Windows 7 has superseded everyone’s expectations, storming ahead of Harry Potter and the Deathly Hallows as the biggest-grossing pre-order product of all-time, and demand is still going strong,” claimed managing director Brian McBride, Amazon UK on October 22, 2009.

  1. At first – thank you for very interesting text which sumarises features of this new operating system.

    I have been using this system for some time for a testing reasons and I was sick of the new task bar. It really doesn’t suit to me and fortunately it can be turned to the old look – but in quite complicated way. When I compared W7 with Windows Vista, it is quite the same system – of course, it has the same kernel. Maybe W7 was a bit faster, maybe it was only placebo effect of MS PR. It means there are no improvements, which I was able to see at first look on my ‘prehistorical’ AMD Athlon 64, 2 GB RAM (I am still talking about speed).

    In my opinion, W7 is good system. It is stable, good-looking and user friendly. But when you have another system installed on you computer, and you are comfortable with it, there is no need to spend money for this. It is evolution but not revolution and it has no killer feature but it has all the properties (good and bad) that Windows always had. Windows XP is stable too (there might be problems with drivers to new devices in a year or two) and Windows Vista SP1 is quite the same as Windows 7, except the look.
    When you are going to by new computer and you haven’t got OS, Windows 7 is the best choice.

    To buy or not to buy. That is the nowadays question. Hope this my report will help somebody to decide. My opinion is really desinterested and dispassionate because I was using MS Windows Xp, Vista and 7 as a slave systems and Linux as a master system so I am really not infected with the WOW effect when new toy is here 🙂

  2. Thank you for very helpful information, which is especially valuable because is based on own experience. I probably let my XP run as far as it works well even if I hear from all the sides what a wonderful system Windows 7 is. Whatever the case may be, many thanks.

  5. You actually make it appear so easy with your presentation but I to
    find this topic to be actually one thing which I think I would by no means
    understand. It sort of feels too complex
    and extremely vast for me. I am looking ahead to
    your subsequent publish, I will attempt to get the hang of it!
