Windows 7 is the operating system of the Windows NT family following Windows Vista. In Windows NT line a system carries version number 6.1 (Windows 2000 — 5.0, Windows XP — 5.1, Windows Server 2003 — 5.2, Windows Vista and Windows Server 2008 — 6.0). The server version is Windows Server 2008 R2, the version for the integrated systems — Windows Embedded Standard 2011 (Quebec), mobile — Windows Embedded Compact 2011 (Chelan, Windows CE 7.0)
The operating system went on sale on October 22, 2009, it is less than in three years after release of the previous operating system, Windows Vista. To the partners and clients having the license Volume Licensing, access to RTM was provided on July 24, 2009. Final (the copy from disks which went then for sale) the piracy version was available to all from the first of August, 2009.
Were a part of Windows 7 as some developments excluded from Windows Vista, and an innovation in the interface and the wired programs. The games Inkball, Ultimate Extras were excluded from structure of Windows 7; the applications having analogs in Windows Live (The Windows mail and so forth), technology Microsoft Agent, Windows Meeting Space; from the Start menu an opportunity to return to the classical menu and automatic attachment of the browser and the client of e-mail disappeared. Also from structure of Windows the Calendar of Windows disappeared.
Use of a system
According to service for collecting of Internet statistics of NetMarketShare for December, 2014, Windows 7 is installed almost on every second computer in the world whereas the joint share of Windows 8 and Windows 8.1 in the market of desktop operating systems makes less than 13%. In an asset of outdated Windows XP the 24.3 percent indicator appears.
The operating system has support the multi-touch management. This opportunity was for the first time shown to Microsoft at the annual TechEd conference ’08 in Orlando. During demonstration assembly of system 6.1.6856 and also experienced model of the notebook about the multi-touch screen was used.
The network Branch Cache technology allows to cache contents of the Internet traffic. If the user in the local area network needs the file which was already loaded by someone from users of its network, – he will be able to receive it from local a cache storage, but not to use the channel with limited capacity. The network cache can work in two modes — Hosted Cache and Distributed Cache. In the first case — the file is stored on the selected local server running Windows Server 2008 R2, in the second case the server is not required, and the cache raspredeleyatsya for storage on computers of users. The technology is expected large networks and is offered for implementation at the enterprises as a part of Corporate and Maximum versions of OS.
About 120 background drawings unique for each country and the language version are built also in OS. So, the Russian version includes the subject "Russia" with six unique wall-paper of high resolution. All versions include 50 new fonts. The existing fonts are finished for correct display of all characters. Windows 7 is the first version of Windows which includes more fonts for display of non Latin characters, than for display of the Latin. The control panel fonts also underwent improvement — by default, in it only those fonts for which layout is set in a system will be displayed. Support of Unicode 5.1 is implemented. The Instant Search search pane distinguishes more languages now. For example, the Russian cases, inducement, a sort, the only and multiple numbers will be recognized.
The additional benefit of Windows 7 can be considered closer integration with producers of drivers. Most of them are automatically determined, at the same time in 90% of cases backward compatibility with drivers for Windows Vista remains.
Windows 7 supports aliases for folders at the internal level. For example, the Program Files folder in some localized versions of Windows was translated and was displayed with the translated name, however at the file system level remained English-speaking.
The new 11th version of DirectX for the first time released as a part of this operating system has the following improvements: support of new computing shaders, a possibility of multithreaded rendering is added, the tesselyation is improved, new algorithms of a compression of textures, etc. appeared.
Windows in Windows 7 OS
The Windows Media Player 12 player received the new interface and became really "omnivorous", unlike the predecessor who needed a large number of codecs for reproduction. However, it cannot reproduce license Blu-Ray disks with video, but has an opportunity to read out and write on them data.
In spite of the fact that the Center of mobility of Windows did not undergo significant changes since Windows Vista, Windows 7 works longer than the predecessor on notebooks and consumes less energy, especially at reproduction of DVD. On the system provided at the end of August, 2009 with two identical notebooks from the preset Windows 7 and Windows Vista the prize made up to 20%. Also the record speed of loading of a system — was shown 11 seconds. A system included a SSD disk and other high-performance components. The similar test inspired enthusiasts to test influence of the browser on lifetime of the battery. The Internet Explorer 8 browser which is switched on in structure of Windows 7 showed the best results on the Intel platform.
Nevertheless, based on independent tests it is found out that Windows 7 much quicker, than Windows XP, puts the notebook battery. Since August experts of the Laptop magazine (laptopmag.com) held testing of the final version of Windows 7, including measuring the battery life of portable PCs under its management. The overall total value was unfavourable: the average netbook under control of "seven" in general works from the accumulator 47 minutes smaller, in comparison with XP. In case of the shortage ASUS 1008HA model made 57 minutes or 16.7%. Other editions also conducted similar researches and also came to these conclusions. Loss makes from 10 to 30 percent on operating time.
The possible reason consists in optimization of Windows 7 under graphics accelerators while many netbooks work on the built-in video cards of Intel and VIA which do not support by an Aero function time. Also many netbooks work running Windows 7 Starter Edition which does not support Aero fully. The lack of support of OS from producers of netbooks is other possible reason. So, Asus Eee 1000HA works with the new drivers and BIOS dated November, 2009 under Windows 7 as long as and running Windows XP.
Function of the Remote desktop also underwent changes. Support of an Aero interface of Peek, Direct 2D and Direct3D 10.1, support of several monitors, expansions of multimedia, DirectShow and also a sound playback capability with low delays was entered.
In Windows 7 more flexible configuration of User Account Control (UAC) which unlike Windows Vista has two more intermediate statuses between the Always to Notify and Never to Notify modes is implemented — "Notify, only in attempts of programs to make changes to the computer" (provision by default), "Notify, only in attempts of programs to make changes to the computer (not to darken a desktop)". It is worth noticing that unlike Vista, shading happens only if the program is active and is in the foreground. If you made click at the time of opening of UAC and deactivated the program, shading can not occur.
Changes are made to technology of enciphering BitLocker, and the function of enciphering of the removable mediums BitLocker to go allowing to cipher removable mediums, and even in the absence of the module TPM is added.
Improvements concerned also the Windows firewall — function of the notification of the user on blocking of the program which tries to get access to network returned.
Using group policy and the AppLocker function it will be possible to prohibit start of certain applications.
The DirectAccess function allows to set safe connection with the server in the background, unlike VPN which needs participation of the user. Also DirectAccess can apply group politicians before user login.
Earlier it was reported that Windows 7 will not use a new core of MinWin as a basis. According to Stephen Sinofsky, the corporation wants that drivers of devices for Vista worked in a new system. Therefore the kernel of Windows Server 2008 will be used. This decision was announced by Stephen Sinofsky at the All Things Digital conference on May 27, 2008.
On November 4, 2008 Mark Russinovich, the member of technical council of Microsoft corporation, in the web broadcasting on MSDN Channel 9 reported that in Windows 7 nevertheless MinWin core is implemented, but the principle of its implementation is based on separation of a core into layers where the basic layer (KernelBase.dll, etc.) totally occupies 30 MB, and other functionality remains in old libraries (for example, kernel32.dll, etc.). For operation of applications and drivers of devices this change imperceptibly thanks to carefully thought over scheme of separation of functionality.
For users of the professional editorial offices the special packet of virtualization which allows to start Windows applications of XP in the environment of Windows 7 at a processor term of use with technology of Intel of VT or AMD-V extends (afterwards this limit was lifted by ), existence of 15 GB of free disk space and not less than 2 GB of RAM (3 GB — for the 64-bit version).
Work on ensuring compatibility is continued also after a release of OS: regularly via Windows Update the updates providing compatibility with older applications and drivers are distributed. Also these updates can not give to the program to be established or be started if it has the status of tough blocking.
Soft blocking gives to the program to be started, however displays the message that the user can have problems with start.
Also, the structure of Windows 7 includes the program which can help to solve compatibility issues. She is called by the %systemroot%/system32/msdt.exe command - id PCWDiagnostic or through the Control panel — Troubleshooting — Accomplishment of the programs intended for the previous versions of Windows.
Rasrytiye of source codes in Russia
In the supplement to agreement between head office Microsoft and Federal State Unitary Enterprise Atlas with FSB the circle of software which source codes open to the Russian side is expanded. The American company needs it for work with a public sector in Russia.
In July, 2010 it became known that the supplement to agreement about disclosure of source codes softwares of the company for Federal State Unitary Enterprise NTTs Atlas and the Federal Security Service (FSS) of Russia is signed. On it the Russian structures got access to codes Windows 7 Windows Server 2008 R2, Office 2010 and SQL Server 2008 R2. The agreement was signed in 2002.
According to the First Deputy CEO of Atlas Alexander Alferov, FSB of Russia are already certified by Windows XP, Windows Server 2003, SharePoint Server 2007 and SQL Server 2008 with the integrated Russian information security tools. The duration of the agreement is not limited now, changes of the code of the products mentioned in it constantly go for the analysis to lack of tabs and vulnerabilities to Atlas. As the signer from the American side the head office Microsoft acts.
After addition signing, as before, access to source codes is got only by FSB and Atlas. However now the Russian agreement parties acquired the right to share to analysis results with "the authorized state organizations". As explained CNews in Microsoft, the choice of these structures does not depend on the company in any way, their list entirely is defined by the Russian side.
Microsoft unambiguously connects expansion of the program with desire to cooperate with the Russian public sector. "The signature of this agreement means for us reaching qualitatively new level of cooperation with state bodies of the Russian Federation", - Nikolay Pryanishnikov, the president of Microsoft in Russia said.
The company openly declares long ago the desire to participate in creation in Russia of the electronic government. The interdepartmental segment working in Great Britain allowing different departments to exchange electronic documents is cited as an example. However, at the federal level now at Microsoft in this direction of implementations is not present, the company cooperates only with certain regions. In Russia there is the second attempt of creation of an interdepartmental segment (at first there was OGITs in federal state unitary enterprise Scientific Research Institute Voskhod, now - works of the electronic government of Rostelecom which became the operator of infrastructure) now, but in one of them software of Microsoft, similar to the British experience, is not used.
Results of sales
For the first half a year of sales the vendor shipped 100 million licenses, 9 months - 175 million, result of the first year of sales - more than 240 million licenses.
For 2010 financial year lasting from July 1, 2009 to June 31, 2010 all on the world 175 million copies of Windows 7 were sold.
In September, 2010 Microsoft announced annual results of promotion of Windows 7 OS in Russia. Its sales started in October, 2009, and by September, 2010 the company implemented about 4.8 million copies from which about a half is the share of sales together with new computers, and the second half – of corporate users. "Boxes" occupy an insignificant share in sales. According to Yury Larin, the acting head of department of promotion of Windows in Russia, the company expects growth in sales of the new platform and in the second year.
Eve Shyonlyaytner, the director of Windows Commercial in Central and Eastern Europe, says that in Russia Windows 7 enjoys bigger popularity, than on average in the world. So, according to an internal research of Microsoft, the universal indicator of "Windows 7 favorability" (the positive relation to Windows 7) is 59%, and in Russia - 72%. China not much more lags behind Russia with an indicator of 69%, in the USA this indicator is a little lower than obshchemorovy - 58%, and in Brazil it is even lower - 54%.
So high popularity of the new platform in Russia in corporation is explained, first of all, with the high level of technical skill of the Russian users and their traditional interest in new products. Larin also reminded that the beta of Windows 7 came to Russia of the beginning of official sales much earlier, and the percent of the users participating in testing was one of the highest in the world.
Microsoft is going to promote further the product in Russia. In particular, the family version of Windows 7 under the name Family Pack will become available to home users soon. According to representatives of Microsoft, this packet will allow to transfer three home computers within one family with Windows XP or Vista to the version of Windows 7 of Home Premium, having saved about 50% on each license.
The offer it will be, however, available only to those at whom license versions of Windows are set, and the offer will work only several months. Approximately sales of Family Pack will begin in November, 2010, and the packet price, by rough estimates of the company, will be 9 thousand rubles.
An opportunity to estimate economic effect of transition of the enterprise to Windows 7 on the website of the supplier of tools of efficiency evaluation Alinean became available to corporate users at the beginning of October, 2010.
The Microsoft company according to the results of February, 2011 recorded that the number of appeals to service of updates Windows Update from the Russian computers from Windows 7 installed on them for the first time exceeded a similar indicator for Windows XP. The marketing manager of Windows in Russia Yury Larin told about this CNews.
"By data for December, 2010 when carrying out similar comparison it turned out that the number of addresses from the PC from the set XP became less, than from versions of Vista and Windows 7 totally, - Larin says. - Now the seventh version for the first time outgrew XP without the aid of other OS".
At a stage of the addressing Windows Update the service does not check a litsenzionnost of the set software so at such technique the number of the OS installations (including piracy), but not sales of their licenses is compared. Control of authenticity can be required for installation of serious updates, such as Service Pack, Larin adds.
Total number shipped to the canal (corporate customers, OEM partner and retail networks) of the licenses Windows 7, according to Microsoft, in the world reached 300 million pieces.
It should be noted that third-party estimates do not confirm big popularity of Windows 7 in comparison with XP yet. According to the statistics Statcounter service which gathers project counters on the different websites worldwide from computers on Windows 7 there are about 30% of the total number of addresses, and on XP - about 48%.
Data on Russia are collected by Liveinternet service, according to its statistics the difference is even more serious. For the last 4 weeks on average 52.2% of visitors of the websites with the installed counters of the project used XP and only 27.5% - Windows 7.
Yury Larin explains this discrepancy with the fact that network counters do not cover all the PC: "Data of Windows Updates are more exact since in them all computers using service of updates regardless of what sites are visited by their owner are considered".
End of support Windows 7
the Free support in the systems of vote in the USA and the countries allies
On September 20, 2019 Microsoft announced preserving of a free technical support of the Windows 7 operating system installed in devices for vote. The company undertakes these measures within own initiative of Defending Democracy Program.

Thus, the free support is provided first of all for security of elections in the United States. However Microsoft states that the similar service will be available also in "other democratic countries entering EIU Democracy Index".
This index is calculated by a technique of the British research center The Economist Intelligence Unit and is based on a combination of expert evaluations and survey results of public opinion from the relevant states.
| ||We also cooperate with large producers who sold voting machines running Windows 7 to guarantee successful installation of any security updates on these systems — Tom Bert reported.|| |

On August 15, 2019 it became known that the company Microsoft blocked installation of SHA-2 of updates signed with certificates for Windows Windows Server 2008 7 and R2 on computers with solutions of security Symantec. Blocking is connected with what antiviruses is deleted by updates during their installation because of what Windows it ceases to be started.

Since August 13 on the PC running Windows 7 SP1 and Windows Server 2008 R2 SP1 the updates signed only with digital certificates SHA-2 will be installed. Transition to this algorithm is caused by insecurity of SHA-1 used earlier. Nevertheless, because of transition to SHA-2 of the solution of security of Symantec (including Norton) began to block or delete updates of KB4512506 and KB4512486 in the course of their installation, and systems ceased to be loaded.
As a precautionary measure of Microsoft temporarily blocked updates for Windows 7 and Windows Server 2008 R2 until Symantec does not solve a problem. According to the notification of Symantec, correction will be available with an exit of the next versions of products.
Completion of official support
In 2019 official support operating system Windows 7 comes to an end. It means that Windows 7 will not receive updates any more security and becomes more vulnerable for malefactors. Also commercial licenses cease to work.

Microsoft announced at the beginning of 2017 that support of the Windows 7 operating system will be stopped on January 14, 2020. The company states that a system became outdated and cannot effectively resist to modern cyberthreats. Microsoft notes that use of the old and any more not supported system are the excess expenses for the user connected, for example, with elimination of effects of cyber attacks. Therefore the company recommends to clients to pass somewhat quicker to Windows 10.
Microsoft assures that Windows 10 is at the moment already more demanded, than Windows 7. On the official page of trends Windows in community Microsoft it it was announced in August, 2016.

Six bulletins are submitted: KB3154228, KB3153727, KB3161647, KB3161897, KB3161639 and KB3163644.
On January 13, 2015 Microsoft officially stopped the main support (Mainstream Support) of the computer operating system, most popular in the world — Windows 7. This step can help the American corporation to raise the popularity of fresher platforms.
Completion of the main support of all versions of Windows 7 (Enterprise, Home Basic, Home Premium, Ultimate and Starter) means that a functional part of OS will not be improved, and will give support to clients of Microsoft only on a paid basis. It concerns both normal users, and participants of programs of corporate licensing.
Microsoft stopped the main support of Windows 7

In addition to Windows 7, Windows Server 2008, Windows Storage Server 2008 and Windows Embedded Handheld 6.5 OS lost on January 13, 2015 the main support.
Microsoft completely will refuse Windows 7 by 2020, but analysts of Gartner recommend to the companies to start as soon as possible planning of transition from this OS to newer. Otherwise they risk not to manage to update completely the systems therefore under threat the information security of the enterprises can get, experts are sure.
