CHAPTER 9. WINDOWS AS AN OBJECT-ORIENTED OPERATING SYSTEM

Currently, most computers and software products operate under operating environments of the Microsoft Windows family (Windows 95 and higher). This environment has become widespread on personal computers due to a number of advantages over previously used operating systems.

The use of environments of the Microsoft Windows family allows you to optimize the conditions for managing applications due to a number of features of both the environment itself and its applications, and the organization of the functioning of the computer and user programs under its control.

Operating systems of the Windows family quickly conquered the software market. This is due to the fact that the Windows developer, Microsoft, has developed a set of software products, the functioning of which has confirmed the advantages of this operating environment.

Operating environments of the Windows family have advantages over previously used environments (especially operating systems of the MS DOS family).

1. Availability of all random access memory Computer for user programs(usually application programs). To work in the Winows environment, the user has access to the entire amount of computer RAM, with the exception of the amount of memory required to operate Windows itself (1-2 Mb).

2. Multitasking and ability to share data between applications.

3. A unified user interface for applications, a unified methodology for working with their (software) objects.

4. GUI for the user, which increases the expressive capabilities of displaying information on the monitor.

5. Automatic row support external devices - mice, CD ROM, etc. (in MS DOS environments, to support these devices, installation and launch is required special programs- drivers).

6. File and directory (folder) names in Windows can be up to 255 characters long(in MS DOS - up to 8).

7. Possibility of getting out of deadlock situations without rebooting the computer. This means that if one of the applications freezes (if it does not affect the functioning of computing system in general) it is forcibly unloaded from memory, after which the user can continue working with other applications.

Latest version of the most popular on the planet operating system from Microsoft, called Windows 10, has long been a topic of mass discussion for millions of users around the world. The first official launch of the updated OS started in Russia on July 29, 2015, but this was preceded by a large-scale advertising campaign from the Microsoft. A fantastic number of trailers, previews, comic commercials were released, including with stars of show business and sports, terribly intrusive advertising pushed to the masses through the Update Center for users of Windows 7, Windows 8 and Windows 8.1. In general, no matter how hard the marketers from the American IT giant tried to promote their new product. But it is worth noting that this has borne fruit.

According to the same intrusive notification from the Update Center (as a process it can be found under the name GWX), Windows installation 10 occurred on the personal computers of more than 100 million users. Some of them praise the new operating system, others call for rolling back to previous versions. And yet, on your computer? Or is it better to stay with the old proven versions? It's time to figure this out. Let's start with each change in order.

New nice design

The version we are considering is based on Windows 8.1. At first glance, they are very similar: tiled design, predominance of blue and light blue shades, lack of widespread use of the 3D effect. If you use the brand new Windows 10 for a week or two, you will see a number of significant innovations from Microsoft. Firstly, this is the implementation of the so-called Design Language 2, which means “design language”. If you long time If you used Windows 8 (or Windows 8.1) and then updated to the latest version of Windows 10, then at first the new design will be a little unusual for the eyes due to a “softer”, smoother image. Icons, buttons, and other elements of the working interface look much nicer and neater than in the predecessor version.

Users of the “seven” will have a more difficult time: in Windows 10, Microsoft developers practically got rid of three-dimensional interface elements, leaving the remnants of the 3D effect only in dynamic menu tiles. If Windows 7 is the crowning achievement of the Bill Gates team in the Aero style, full of colorful multi-colored window panels and menus, high-quality shadows and volumetric elements, then in the design of the “ten” you will find the perfect embodiment of minimalism. Large, immutable fonts, which often caused long file and folder names to extend beyond the allotted window space, have been replaced with dynamic ones. Unfortunately, not everyone accepts this style in modern design, so the question of whether it’s worth installing Windows 10 if you’re used to the classic design is often decided in favor of the “Seven”.

Good old "Start"

Perhaps the most significant change for many users compared to Windows 8 is the long-awaited appearance, or rather, return, of the Start menu. Although the developers returned the button with the operating system logo to the familiar lower left corner in version 8.1, its function was completely different: when you clicked on it, you went to the tiled menu of applications in the Metro interface (later this name was replaced by Microsoft Design Language).

The new menu combines elements of the “Start” from both “seven” and “eight”. In addition, it has become customizable: each user can choose one of three display options. The first offers the design of the classic Start menu from version 7 combined with small tiles of the most frequently used applications. The next option is a menu from Windows 8/8.1, only with a tiled interface. And finally, the final option is a hybrid Start menu. Through it, the user can access both classic programs and Microsoft applications.

By the way, speaking about the latter, it is worth mentioning that not all functions have been transferred from the classic MS Windows 10 interface to new applications. Let's take the simplest example - the control panel. It would seem that this window should be functionally replaced by the Settings application. But if you compare the set of functions, you can easily see the difference in the number of settings in favor of the control panel. The same applies to the device manager.

Voice assistant on a personal computer?

Yes exactly. Microsoft developers again decided to borrow a couple of ideas from their mobile versions of operating systems. This time we see an absolute innovation that is not found in any other version of Windows. This voice assistant. In iOS, Android and Windows Phone This is not an innovation for a long time, and such a function on smartphones is very popular. The voice assistant on the 10 will be called Cortana. The name is not new, since in the mobile version the assistant is called that. On the one hand, it's just a voice navigation built into the taskbar. In fact, Cortana is a very useful assistant. With its help, you can manage virtually all processes that occur in the operating system. Apps, recommendations, weather, reminders, notifications - all this and much more is easily managed using Cortana.

There is only one significant problem: lack of support for the Russian language. It’s a pity that Russian users who don’t know English won’t be able to communicate with their computer, but in general we can count on the Americans to take pity on us and release our Cortana. Currently, the voice assistant can be used by speakers of English, French, German, Chinese, Italian and Spanish languages. There are also plans to expand support to Japanese, Indian and Portuguese.

Notifications now on desktop

Anyone who uses a smartphone with any operating system, including Windows Phone, is accustomed to pop-up notifications about new messages in in social networks, SMS messages, low battery percentage and downloaded document. However, this series can be continued endlessly. The development team from Microsoft decided to transfer this experience to the desktop version of the operating system. Although this is not the first attempt. Windows 8 also tried to implement a notification system, but the idea was too crude. During the time between the releases of the last two versions of the OS, it was refined and improved, after which a completely updated Notification Center was added to the top ten. It collects all notifications that notify the user about various events. Through this Center you can also disable notifications (all or partially), configure their form, frequency, and so on.

A very interesting feature of the Notification Center is the presence of a panel of quick switches. This has never happened before in any version of Microsoft Windows. However, to the same users mobile devices This thing is very familiar. The developers again borrowed one of their achievements from mobile operating systems. You can turn on geolocation, connect to the Internet, activate Do Not Disturb mode and adjust the screen brightness in just two clicks.

So on your personal computer?

So, we have dealt with the main innovations. Now let’s decide whether our computer needs to install Windows 10. Many changes, updates, fixes of the new operating system allow each user to see a serious difference compared to the “seven” and “eight” and decide for themselves whether to switch to new system, or is it better to stay with the familiar working interface.

In order to understand this difficult issue, let's go through the Windows 10 system. Let's start in order.

New opportunities

Having seen the innovations that we listed in the first half of our article, you will certainly understand that Windows 10 is a completely new era in the development of the operating system from Microsoft. The notification center, voice assistant, and updated design are noticeable progress compared to previous versions of the OS. The innovations we have listed are by no means an exhaustive list.

Update to version 10586

The latest Windows 10 update was, one might say, global in nature. This update was released on November 4, 2015 and is currently the latest official update that the Windows 10 system has received. Version 10586 makes it the best “operating system” that humanity has ever encountered. Improvements, corrections, addition of new features - users of the new development liked everything.

Unlike the previous version of Windows 10, this is a noticeable leap in terms of detailing and bug fixes. The main topic of discussion in the global Internet community was the collection of information carried out by Microsoft. In fact, everything could be transferred to the American giant’s database: passwords, browsing history of Internet resources, data on connected networks, user files and information about them. Naturally, such chaos worried people who switched to the new Windows. Microsoft eventually backtracked on its new policy, adding advanced privacy settings that can be accessed through the Settings app.

In addition, users may have noticed that other Windows 10 errors have been fixed, including a delay when turning on some applications, conflicting regular programs for Windows 10, crashes and system crashes. All this allows you to learn a new OS without unnecessary nerves.

A New Approach for Desktops

As you may have already noticed, Microsoft has borrowed a lot from mobile operating systems. The voice assistant, notification center, and quick switches are familiar to most users from Windows Phone, as well as Android and iOS. Many people liked such innovations, although at first it was not entirely customary to see them in the desktop version of the operating system. Programs for Windows 10 have become unified, and now they can be used both in tablet mode and when working with laptops and desktop computers.

Lots of bugs

Still, “ten” even with latest version the update remains quite “raw”. As participants Windows programs Insider (a system for recording deficiencies in beta versions of updates), and ordinary users of the new operating system continue to notice various errors. Windows 10 needs improvement, and Microsoft experts understand this very well. Of course, it was quite difficult to call it the final version at the time of its official release. But even today, with the latest update to version 10586, it’s hardly possible to call Windows 10 perfect.

Partial support for Russian language

After reading this, you will think that the Russification of the system is fragmentary. No, that's not true. The entire working interface of the system was well translated into Russian, since Russian specialists were involved in the translation. But in some small details, there is still discrimination (let’s call it that) against the domestic user on the part of the American developer. This concerns two main aspects: the voice assistant and applications from the Windows Store. But if the latter depends largely on the developers of the applications themselves, then Cortana by default is not equipped with understanding of Russian speech.

Let's hope that the Windows 10 assistant in Russian will be available in the next updates.

Activation

Microsoft is trying to convince everyone that the system is distributed free of charge. In fact, after a year of use, you will be offered to purchase a license. What will happen to those who do not purchase the coveted Windows 10 activator is unknown. But one thing is clear: at Microsoft no one is going to work to their detriment. If you fail to obtain a license, then perhaps you will either have severely reduced functionality, or even be asked to roll back to previous versions (although the latter is unlikely). Although, most likely, thanks to our fearless hackers, a pirated Windows 10 activator, for example, KMS, will appear.

What is the result?

To sum up our reasoning, one thing can be said unequivocally: the new operating system is intended to become the starting point for the emergence of a single operating interface from Microsoft for all devices, attracting with its versatility, minimalism and practicality. Is it worth installing Windows 10 on your Personal Computer? The answer to this question can only be given by personally trying out all the innovations and understanding for yourself whether it is convenient for you to use such an operating system.

Disadvantages and advantages of Windows Windows is, today, the most widely used operating system produced by Microsoft Corporation. The Windows XP operating system has been produced since October 2001 and is a continuation and development of Windows 2000. What the name itself says: XP - from the English. experience. Unlike the previous model, Windows XP is an exclusively client version, suitable for individuals for personal and work use. The server version of this system is, released later, Windows Server 2003. Both operating systems are built on the platform of the same kernel, therefore they are developed and updated in parallel. There is the following gradation: Windows XP Professional Edition and Windows XP Home Edition. Windows XP Professional is an operating system designed for use for corporate purposes, businesses and entrepreneurs. A feature of this Windows is file encryption using the Encrypting File System program, the ability to centrally manage access rights and support for multiprocessor systems, remote access to the desktop, etc. Windows XP Home is a lightweight and stripped-down version of XP Professional. Unlike its older brother, XP Home is noticeably cheaper, but if you install certain programs and carry out updates, the version can be expanded to the full-fledged XP Professional. Pros and cons of Windows XP Pros: - Multi-user system. Separation of access rights to various directories and launching programs and applications. You can also quickly change the user and run programs with the rights of another. - Interface. Appearance XP is convenient and attractive. Many programs and drivers for the design of your personal Windows can be downloaded on the Internet (for example: styles, bootscreens, plugins, logonscreens, etc.). It is possible to install new design systems. Each style element is independently customizable. - File system. Transaction support allows you to conveniently and fearlessly use files, freely move documents from place to place, without fear of sudden system failure or power outage. The data will not be erased, but will remain intact. The NTFS 5 file system makes it possible to separate the attributes of files and folders for access. There are many more options related to encrypting and compressing certain files and folders to save disk space. - Protection. The XP kernel is secured by separation of security rings. The kernel is located in the third ring, from where you can command the hardware (ring0), and for example, in the third ring (ring3) there are user applications, and the equipment is not directly accessible from there. In the depths of Windows XP there are many programs hidden that prevent the spread and non-stop absorption of data by Trojans or other viruses. There is one more secret: to work, in addition to the administrator account, you should create another one - a limited account. And all operations are carried out in it. If you catch a virus, it will not have all the privileges of an administrator account. - Stability of work. Windows XP has restore points. Therefore, in the event of a system crash, when you call a specialist, it is possible to completely restore your programs, documents, favorite photos, music and videos. Minuses: - System requirements. XP is quite a gluttonous system. The processor requires at least 500 MHz frequency and more than 128 MB of RAM. - Incompatibility of components. There are often questions about unsuitable hardware for a computer. In fact, the issue is not in the components, but in the drivers, for advice and correct installation of which it is better to contact a specialist. - Software incompatibility. Just like with drivers, Windows XP can be capricious with programs. Windows Vista is a newer client operating system. For corporate clients, there is Windows Server 2008, which also has its own Office 2007. Windows Vista has been updated with new features, such as Hybrid Sleep. has several types. The most common: Vista Home. Supports up to 2 processors, touch screens, and automatically backs up information. Vista Home does not support EFS file encryption and does not have the ability to join a domain. Vista Business supports up to 2 processors, but does not have parental controls, entertainment applications are cut down and the entire multimedia part is very modest. But it is possible to work in a domain, file encryption system - EFS. More suitable for offices and work computers. Pros and cons of Windows Vista Pros: - Fast loading, unlike Windows XP - Nice graphics and an improved logical model for how graphics interact with devices. - Possibility of using the capacity of external media as RAM, via USB. Experience has shown that this increases productivity by 30% - Improved security. Compared to Windows XP, Vista has proven to be less vulnerable to viruses, worms and Trojans. Also, at each security ring, the system requests data and passwords, thereby monitoring the I/O window and preventing third-party programs from capturing data. - EFS file encryption system. Only Windows Vista Business and Ultimate grades have this system. It is needed to create and encrypt files, change the length of the user key, store the key, and request encryption of user folders. Cons: - Slow action. Often, only some Vista programs run faster, otherwise you have to wait an extra minute - Required digital signature. Digital signature - verification and uniqueness of a digital document. Previously, users could differentially digitally sign, but to work in Vista this is necessary condition , which makes working with open drivers much more difficult. - Test "Hardware Functionality Scan". This Microsoft test is designed specifically to test new hardware, which must be passed, otherwise Vista will not allow the component to be played. Windows 7 can be positioned as “anti-Vista”. “Seven,” for example, doesn’t even try to dazzle you with flashes of new visual effects. With the removal of Vista apps like Photo Gallery and Movie Maker, Win 7 is truly capable of less than Vista. Even its off-putting name speaks to this – a departure from the “epoch-making”, pompous names that began with the unsuccessful Windows Millennium Edition. However, the lack of external gloss is a huge advantage of Windows 7. Unlike the increasingly chaotic, annoying users of Microsoft's predecessor operating systems, Windows 7 is designed so that there are no complaints about this and one can work efficiently and usefully. Although, like any software, the new operating system has both its pros and cons. Let's take a quick look at some of them. Pros: Windows 7 doesn't consume memory resources as greedily as Vista. One of the many shortcomings of the original version of Windows Vista was that the beautiful Aero interface ate up so many resources that the majority of computers from the early 2007 model simply physically could not handle the new operating system, even though they were labeled “Vista capable.” The “Seven” will have no problems with loading speed and its operation (even on small and low-power PCs, known as netbooks, as you know). The Taskbar has been radically updated - the developers have finally come to the rescue, because after Windows 95 this panel and the system tray underwent only minor changes. In Windows 7, both the panel and the tray were “cleaned up” and, although belatedly, “refreshed”. And for the most part, the results are extremely pleasing and pleasing to the eye. The Windows 7 taskbar provides better preview capabilities, context-sensitive Jump Lists, and other features that help speed up the process of managing applications and windows. The new Taskbar doesn't have pop-up text messages by default and relies solely on icon icons, so it makes better use of screen space. Its “previews” are a step up from its predecessor, and work great even when you have multiple windows open in the same application. And a new right-click Jump Lists feature gives you access to a context-sensitive menu of features (such as Windows Media Player's ability to shuffle music) even before the app is launched. . The new system tray (also known as the notification area) provides highly precise control over active applications. Overall, the innovations in the Taskbar are welcome, although the boundaries around active applications are not clearly visible. We can only welcome that Microsoft has sharply reduced the amount of auxiliary “pop-up” information that distracted, irritated and bored many users. The infamous function, designed to protect the user's security, User Account Control, is now also not so annoying to users. After all, Windows Vista, roughly speaking, simply bores users by constantly monitoring Accounts user, in an attempt to prevent you from becoming infected with viruses and other malware that may manipulate your system. Windows 7 has two intermediate settings that only sound the alarm if the program changes the installation settings. Moreover, in new version The approach used is so smart that it becomes even more of a mystery how Microsoft managed to solve this issue so poorly and poorly in the Vista version. For years, Microsoft has been trying to get Windows users to keep all their personal files in one place, courtesy of the My Documents folder. However, many of us blithely ignore this suggestion and keep files wherever God wishes. Windows 7 has a new feature called Libraries, which provides virtual folders for documents, music, photos and videos that combine the contents of folders you point to for a single view. For example, the Image Library shows absolutely every photo, even if they are stored in dozens of different places. However, there is room for further improvement - this feature would be even more useful if it were integrated with the existing Saved Search feature, creating another new, separate virtual folder. A lot of interesting things can be expected from the fact that Windows 7 is the first version of the OS with special support for multitouch input. For example, if it notices that you opened the Start menu with your finger rather than your mouse (which requires a touch screen, of course), you'll see a version of the menu with less navigation precision. However, Windows 7 can bring with it an abundance of new and interesting applications. Cons The HomeGroups feature, which allows you to distribute media functions, sounds cool, but disappoints upon closer inspection, because it only works with PCs running Windows 7, and generally looks a bit damp. The idea itself is great! HomeGroups is a way to share folders full of media files and documents between computers over the network, so you can, for example, admire the photos that are stored on the desktop in your office or on the laptop in the living room. However, the implementation of this idea is surprisingly “unimplemented”. For example, instead of allowing you to specify a password yourself during installation, it is assigned by the computer and consists of ten alphanumeric gobbledygook that you must also write down so as not to lose it. Moreover, HomeGroups also only work if all computers support Windows 7. Although an option that would also work with XP and Vista, not to mention Mac OS, would be much cooler. It's also bad that you can't upgrade directly from Windows XP. If you want to upgrade your PC from XP to Windows 7, you need to start from scratch, reinstall all applications and re-create your settings. (But a Windows Vista user can choose to install “Seven” on top of his current OS, although not for all occasions). Microsoft's decision to not allow XP to be upgraded to Windows 7 is to some extent justified - a new install will likely be more reliable than installing over 8-year-old XP. There is no reason to believe that Windows 7 will require fewer patches than earlier versions of operating systems. If you use the Microsoft-recommended update method, it can take quite a long time because your computer will still require you to close it so it can update, then reboot, etc. Win 7 is largely compatible and well thought out overall. It's an aggressive, retro approach to updates that smacks of the same assertiveness of the Windows of yesteryear. Windows 7 looks and works differently than Windows Vista, but if you dig deeper, the differences aren't that drastic. Small headache Incompatibility of drivers and software is expected, but, as experience has already accumulated, even early preview versions of Windows 7 worked surprisingly without failures. However, when millions of people install Windows 7 on an endless number of their PCs, it's unlikely that everything will go without a hitch, and they're likely to run into problems that Microsoft didn't foresee. The shortcomings of Windows Vista have been written, rewritten, spoken and discussed. Microsoft itself admitted and acknowledged its failure. All sorts of marketing attempts to “whiten” Vista’s reputation led to virtually nothing. It can be assumed that this time users will be more cautious about migrating to a new operating system. Caution never hurts. Many of those who install Windows 7 at the first opportunity will be happy with what they did. Others will prefer to let everything settle down first, so that there are no unexpected glitches with applications and drivers - and they will be even happier. If you have one already obsolete computer, it is quite advisable to postpone the purchase of Windows 7 until the time when you are ready to buy a new PC on which “7” will already be installed. (Based on an article by Alexander Levshin)

Windows 7 is a productive and multifunctional system, which, compared to other versions of operating systems, has an impressive number of new functions.

Pros and cons of Windows 7

Pros:

1. Clean Windows 7 is installed on most modern computers, netbooks and laptops. As a result, it is much easier to restore the original system after exposure to viruses and perform other common procedures.
2. Work stability. However, it depends largely on the Internet connection, the hardware used, installed applications, driver versions, correct settings, availability of updates, and so on.
3. User-friendly interface that differs in design styles and bright colors
4. The original Windows 7 has a high level of resistance to careless and erroneous user actions, which predetermines the choice of OS.
5. The list of settings is quite rich - from graphics to security settings and access rights.
6. The original Windows 7 is compatible with almost all modern common programs.

Even with the number of features available, Windows 7 has a number of disadvantages.

Minuses:

1. Windows 7's Explorer is quite simple. Working with him is a bit difficult.
2. Windows 7 includes many settings, some of them are in the “Registry”, others are located in the “Control Panel”. As a result, making adjustments is not very inconvenient. After all, the reliability and uninterrupted operation of Windows 7 depends primarily on how correctly the settings are made.
3. Windows 7, unlike such systems as XP or Vista, is low-speed. That is why, in order to achieve certain results, it needs much more resources than other operating systems.
4. Relatively low overall protection. For example, if a person wants to install additional applications, then such manipulations can lead to unpleasant consequences, and in order to restore the previous original system, you will have to use a program to change the registry.

Windows 7 is not perfect, but by using methods that reduce the disadvantages and increase the advantages, you can get an excellent operating system.

Currently, there are various operating systems for computers, but the greatest demand is in Lately It is Windows 7 that he uses. At the same time, you can now buy Windows 7 in two versions: home basic or extended. Professional and most full version, of course, is Windows 7 64-bit, which fully reveals all the capabilities of this operating system.

However, the difference between the 32-bit and 64-bit versions of Windows 7 is the amount of RAM that can be addressed by your processor. Simply put, how much RAM your processor will have. Thus, Windows 7 on 32-bit cannot use more than 4 gigabytes of RAM, and in reality this version will give you the opportunity to use not all 4 gigabytes, but only 3.3 gigabytes. But Windows 7 at 64-bit can use 4 or more gigabytes of operating memory. Now you can buy this version via the Internet on the website: http://1001-soft.ru/Microsoft_Windows_7.html.

The main advantages of Windows 7 at the moment are the following:
