Windows 10 activation works. Activation after reinstallation

The Windows 10 distribution system keeps up with the times. Now there is no need to buy a disc in a store or order it on the Internet. Absolutely every user can download Windows 10 to their computer directly from the official website of Microsoft. But this version will become full-fledged only when it is activated.

Reasons to activate Windows

The non-activated version of Windows is essentially a trial product. You can use it for a long time until you decide to purchase a license key. In this case, of course, some features in the non-activated version will be blocked or limited:

• all Windows 10 personalization options will be disabled. This means that you will not be able to install wallpapers on your operating system, select colors, and so on. The theme will be available only selected by default, you will not be able to create your own. Considering how flexible the personalization settings in this system are, this is a serious limitation;

  Theme selection will not be available in non-activated Windows 10

• A watermark will appear on the desktop informing you that activation is required. This sign will be on top of all running programs or games. It is distracting and just looks ugly, which, of course, is important for users;

  Windows Activation Reminder will stop you from working

• lack of official support from Microsoft: after purchasing a license, you become a client of the company. This means that it is obliged to provide you with technical assistance in the official forums and fully support your product. This also includes regular system updates, which only the activated version of Windows 10 receives.

  Only activated versions of Windows 10 receive full support companies

It turns out that work on activated operating system not only more pleasant and convenient, but also more reliable. After all, many updates relate primarily to the security and protection of your computer.

Activating Windows in various ways

Regardless of which version of Windows you are using (Home, Pro, corporate or others), you can activate it different ways, even with a key to a different version. Among the activation methods there are both legal ones - with the acquisition of a key - and illegal methods. Whether to use illegal activation methods or not - this choice always remains on the user's conscience.

Activate Windows 10 via command line

Very in a simple way activation is activation through command line. This will require literally a couple of commands, but first you need to open it:

This will open the command prompt. Follow these steps:

If the activation is successful, you will receive a notification about it. After that, you can close the command line.

Entering the activation key in system settings

Another activation method is activation through system settings. Do the following:

You can also activate in the computer update menu:

Regardless of the method chosen, the result will be the same: your system will be activated if the key is entered correctly.

Windows 10 activation without internet

The official activation process itself involves contacting Microsoft servers to confirm the key. Therefore, activation without the Internet can be understood as:

• delayed activation during Windows installation, which will be carried out as soon as the computer connects to the network. So, for example, you may have a digital license (for example, when upgrading from a licensed version of Windows 8.1), in which case you will not be asked for a key, and activation will take place automatically when you go online;
• activation by phone - it is possible to activate Windows 10 by phone using Microsoft's automatic assistant;
• activation through an activator program - there are illegal activators that can work without the Internet. They do not activate the system directly, but make the computer consider it as such, removing all restrictions imposed.

OEM activation of Windows 10

The OEM in the version name refers to the distribution type of the operating system. This means that the system was pre-installed on the computer to be sold along with it. So, when buying a modern laptop, you will receive a device with an OEM version of Windows 10. At the same time, you will not be given a key to the operating system directly, it will be tied to the laptop motherboard.

If such a laptop lost activation when reinstalling Windows, it would be nice to know your license key. This can be done using the ProdeKey program, which will reveal the key associated with your equipment. This program serves the sole purpose of showing you the key to your operating system.

This program will allow you to find out the key associated with your equipment

After you recognize the key, you will only have to activate the system using one of the methods described above. Activation in this case will be completely legal, because you purchased this version of Windows along with the hardware.

Sometimes you can find a license key right on the body of your laptop or computer in the form of a special sticker.

Activation code stickers may look different

Activate Windows 10 by Phone

The way to activate Windows 10 by phone is convenient when there is no way to go online. This type of Windows activation requires the following steps:

Possibility to delay activation

All the legal methods described above will activate your system forever. As long as you don't reinstall it or replace key pieces of hardware, you won't need to reactivate it. In the case of illegal methods, no one knows when your Windows activation will be reset.

But there is another officially approved method that activates Windows temporarily. It is done like this:

In this way, you will delay the need for activation for a month and will be able to continue to use your operating system to the fullest. You can do this only three times, then this opportunity will not be available.

Windows activation via KMS activator

Mentioning the activation methods, one cannot help but talk about the most popular unofficial program for activating Windows. Its features are:

• supports all modern operating systems, any of their versions;
• completely free;
• conducts high-quality activation with the function of maintaining it in the future if desired;
• has many settings for experienced users and the ability to activate in one button for beginners.

Using this program is really very simple:

Get the Education edition of Windows

There are several editions of Windows specifically for educational institutions. They differ from the usual ones in more advanced functionality, programs for conducting tests and changed default settings. And, of course, there is a separate version of Windows 10 Enterprise, created specifically for educational institutions.

There is a special licensing system for such products, as well as separate prices. However, you will have to officially confirm that you are an educational institution to receive these benefits. The purchase procedure itself should take place through official Microsoft resellers.

There is a convenient system for selecting a supplier for your educational institution

Otherwise, the activation process for such operating systems does not differ from the activation of other versions. In the same way, you can activate Windows yourself through the system settings or use third party programs to activate.

Windows activation after motherboard replacement

Like the previous operating system, Windows 10 "remembers" the hardware of your computer when activated. When it is seriously changed, for example, when replacing motherboard, activation may fail. If you have a license key or have upgraded unofficially, your steps are clear. You just need to re-enter the key or re-activate. But what if you received a licensed version of Windows 10 as a result of a free upgrade? In this case, you do not have a key and you will have to act differently.

Before the release of the anniversary windows updates 10 the only solution was to contact technical support. There I had to describe the situation and after a private review, Microsoft technical support employees made a decision and returned the activation manually. Now this process can be done automatically. Do the following:

After that, the activation will return to its place, and you can continue working. In any disputable situations or if this method does not help, you still have to contact technical support.

We keep Windows activation when reinstalling the system

Many digitally activated users (that is, those who upgraded for free at exit new system) are afraid to reinstall Windows. “After all, with a clean reinstallation, all files from the computer will be deleted, which means activation will also fail,” users argue. In fact, this statement is not true. Activation will take place automatically if:

• when you reinstalled Windows 10, you did not replace the motherboard or other hardware;
• you are installing the same version of Windows that you already have installed.

That is, the main thing is not to try to install a different version using your license key. It must completely match the one that has already been activated.

For any issues with reactivation, Microsoft suggests contacting Technical Support or using the Activation Troubleshooter.

Reappearance of the inscription about the activation of Windows

If the message about the need to activate Windows 10 returned to your desktop, this may be due to one of two reasons:

• or Windows activation was performed insecurely, and on this moment your operating system has returned to an inactivated state again;
• or an error solely in the return of the inscription, despite the fact that the system itself remained activated.

In the first case, you need to reactivate the system by one method or another. In the second, you can handle the simple Universal Watermark Disabler program. Take the following steps to get rid of the activation notification:

Windows activation issues and errors

Let's look at the most common problems associated with activating Windows.

Windows 10 won't activate after installation

If you are unable to activate Windows after reinstalling the operating system, there may be several reasons for this:

• during a restore, upgrade, or Windows installation 10 was used not the version of the operating system for which you have a key;
• the copy of Windows you purchased was installed on several different computers. The license agreement allows activation on multiple devices, but this activation may fail if used at a time;
• using an unofficial Windows image;
• significant changes to your computer hardware.

How to act with some of these factors, we have already described above. In any case, if you have problems with the official activation of Windows, you can always contact Microsoft technical support for help.

The system asks for activation, but it is activated

This failure may occur in the following cases:

• if your Windows 10 has not been updated for a long time. In this case, just update it to the latest version;
• if your computer does not have an internet connection. The system cannot verify the authenticity of your key;
• Microsoft servers are overloaded. Because of this, some of the data may be issued in the wrong way, leading to one or another failure.

Other Windows 10 activation errors

There are other Windows activation errors. Usually they are indicated by one or another code: 0xC004F210, 0xC004F034, 0x8007267C. The solutions to these errors differ from each other, and the causes of their occurrence can be divided into three simple categories:

• key entry error on your part. You just need to enter the key more carefully or verify its authenticity;
• Internet problems for the user. Establish a secure connection before attempting to activate the key;
• Microsoft network problems. Due to technical work or heavy load, this can also cause the system to be unable to activate. In this case, the only thing left to do is to wait.

The one-stop solution to any problems that caused errors is to contact technical support or run the activation troubleshooter.

During the installation of the Windows 10 distribution kit, the software product is activated, which allows the user to fully use all the features of the operating system. Activated version Windows 10 makes it possible to avoid such unpleasant problems as periodic sudden reboots, the inability to configure your profile, and the constant pop-up watermark reminding you of the need for activation. The activated product enjoys official support developer. But sometimes there is such an event as the termination of the activation. This can happen for various reasons, depending and not depending on the actions of the user. Then the question immediately arises of how to restore the failed activation. Until the activation is restored, working with the deactivated version of the system will not be entirely comfortable and correct. It is for these cases that the developer provides a number of specific actions, by performing which you can restore activation.

Why does Windows 10 activation stop working

Unlike previous editions, Windows 10 uses a completely new activation algorithm for the distribution package installed on the computer.

When purchasing a licensed distribution kit in a store and installing it on a computer, the user enters the license key only once. After the first activation, information about the system and its components is stored on Microsoft's activation servers, and in the future, the activation process on this computer will take place during any reinstallations automatic mode.

If the installation of Windows 10 took place during the upgrade process from older operating Windows systems 7 or 8.1, then the valid activation status was checked by the Windows 10 setup program and a digital license was generated on the activation server.

At the same time, a unique computer identifier was created and information about the electronic components of the device was stored. When you reinstall the system, a digital license will automatically activate the distribution. This activation mechanism makes it possible not only to reinstall Windows 10, but also to perform any operations with the hard drive, including formatting. Anyway, the system will be automatically activated at the first start by contacting the activation server.

Despite such a thoughtful activation algorithm, sometimes it fails. In this case, the activation simply ceases to operate and the system begins to be considered deactivated, with all the ensuing consequences.

When the activation is terminated, the message “Evaluation copy. Expires…”, which means. that the version is trial and will expire at the specified time

Unfortunately, the developers of the tenth edition of Windows could not foresee all the situations that affect the activation process and its possible failures. Activation may cease to be valid after reinstalling Windows 10, upgrade any program components or replace the computer motherboard. These are the most common cases of termination of the activation status of the system.

To return the activation status, the developer has set certain rules for users. In addition, there are additional ways activate the system.

Activation expired after reinstalling Windows 10

Windows 10 activation is terminated after the system is reinstalled on computers that do not have access to the Internet, as well as in cases where the connection to the activation servers is lost or the connection to the server fails when the computer accesses the activation servers. In this case, it becomes necessary to repeat the activation process. This can be done in two ways.

The first is using a 25-digit license key obtained when purchasing a Windows 10 distribution in the store.

The second way to go through the activation process again is using a utility designed for digital licensed versions.

Video: Repair Windows 10 activation by phone

Please note that only those users who have already activated Windows 10 with a key or received a digital license when migrating from older editions of Windows can activate by phone.

Activation expired after Windows 10 update

If after installing Windows 10 the option was not disabled automatic update system, then all updates that periodically come to the computer from the developer will be installed automatically. When updating very important point is a reliable internet connection. If, when updating system files, it was not possible to connect to the Internet, the connection was unreliable or periodically disappeared, or the Microsoft activation servers were excessively overloaded at some point, then a failure could occur, leading to the termination of the activation status, after which the system begins to be considered deactivated.

Restoring the activation status can be done in two ways - using the utility for working with a digital license or using the license key received upon purchase. In addition, it is possible to install a new release of Windows 10 from the Microsoft website.

On the official Microsoft website, go to the "Products" tab

In the "Products" go to the Windows tab, in the drop-down menu, select the item Windows 10 and then the item "Switch to Windows 10".

Select the "Upgrade to Windows 10" tab

Activation servers store data about the identification status of your computer after the last installation of the system. That's why clean install does not require you to enter a license identification key. After installation, it is recommended to create installation media on a DVD or USB drive in order to be able to perform a system restore.

Termination of activation after replacing the motherboard

When Windows 10 is first activated on the Microsoft activation server, it is linked to the computer and a unique identifier is created, which allows you to get by with only a digital license in the future and makes it possible to do without a 25-digit license key. Microsoft does not publish the algorithm for generating this identifier anywhere, but it is known that it is tied to the system motherboard. Thus, you can safely replace components such as a video card, hard drive or RAM if they are installed in the corresponding motherboard slots. If the motherboard is integrated or activation was carried out with an additional network card, there may be problems when replacing them. When replacing the motherboard, it will definitely be considered a Microsoft activation server as new computer, not tied to the installed Windows 10. In this case, you need to contact the hotline or contact Microsoft support. If you have a licensed copy of Windows 10 installed, then the issue will be resolved in your favor.

If activation interferes antivirus program, then you can temporarily disable it or add activation files to the antivirus exclusions.

What to do if Windows 10 activation is missing

In the event that the user cannot restore the missing activation of Windows 10 in any way, or he did not switch from the old edition before, but now he finally decided and does not have a digital license, then there are two ways to activate your operating system. Each of them has its own advantages and disadvantages.

Joining the Insider Program

The Insider Program makes it possible to legally obtain a new edition of Windows 10 without having a digital license obtained when migrating from an old edition of Windows 7 or Windows 8.1, or entering a 25-digit license key. The program is designed for preliminary evaluation and testing of a new release of the program. Participants get the opportunity to work with the licensed edition of the program, but it must be borne in mind that the assembly with which the user will work has not been completed and has certain inconveniences in use. The digital license of the test edition will not allow the activation of the system in the same way as the real holders of the license key or digital license. A watermark will often appear at the bottom of the desktop reminding you to activate, and new releases will often arrive that take time to update the system. To plug test program it is possible with "pirate" or unlicensed version Windows 10 when it starts asking for activation.

To become a member of the Insider Preview program and become a legal user of Windows 10, you must do the following:

You can also connect to the insider program through the official Microsoft website.

The official website of Microsoft Corporation is not very convenient to use, especially when searching for a product. First you need to understand its structure in order to understand where and what to look for.

How to activate Windows 10 if there is no activation key

Activating the system is quite simple if you follow the instructions. The operating system will ask you to enter a key, which consists of 25 characters. But, there are other tricks.

For example, if the computer had the seventh or eighth version, then the update will not require activation at all.

If software is installed on a new one, then a license will have to be purchased. But, if there are no funds for a license or you just don’t want to pay for it, then you can use special programs that solve this problem.

There are a large number of activators for pro And home versions. After this procedure, "Personalization" is unlocked, as well as a number of other functions. We will analyze the principle of using some of them in more detail.

To personalize your computer, you need to activate Windows 10. What happens if you do not activate Windows?

You can use Windows 10 without a key, but there are a number of difficulties that prevent full use.

In the lower right corner, after each system startup, a watermark "Windows Activation" will appear. In addition, there are no significant irritants. But it will be impossible to change the screensaver on the desktop and everything related to personalization.

But the craftsmen came up with a way to unlock personalization without various activators. It should be noted that this way does not work for everyone.

Unlock personalization

The essence of the solution to the problem is extremely simple. You need to turn off the Internet and restart the system. These are all the steps required to unlock personalization.

Why does this method work? The whole point rests on the computer's access to Microsoft servers. Without access to the Internet, it is impossible to determine the legality of Windows. Accordingly, if there is no way to authenticate, then it is wrong to block functions.

To turn off the Internet, follow these instructions:

• It is necessary to find a triangle in the lower right part;
• Right-click on it and select "Network and Sharing Center" public access»;
• Click on "Change adapter settings";
• Disable all connections by highlighting each icon and clicking on the "Disconnect" item.

After the operation, all the features are unlocked, and you can freely use all the functions. You can change the wallpaper, screensaver of the lock screen. After replacing everything you need, you can turn on the Internet again. The next time you contact Microsoft servers, it will be clear that there is no license, which means that a warning will pop up again. Only all changes are saved. This method is for those who do not have time to fully activate Windows.

Conclusion

There are a lot of options for activating Window 10, and which one to choose is up to you. Activators allow you to solve the problem once and for all, and absolutely free. But, they also have problems. For example, the next time you update, you may need to reactivate.

By purchasing a license, you can no longer worry about this problem. Even in the event of an incomprehensible situation, calling Microsoft technical support will solve the problem in a few minutes. Therefore, if Windows 10 requires an activation code, do not despair.

Why the best? This method has three very important advantages, and one of them is not replaceable by any other options at all:

1. Firstly, Windiws 10 will be downloaded directly from the Microsoft website, that is, the system will be licensed. And that means you get maximum performance and security. You yourself understand that any pirated copy of the OS will be changed in taste and color by the author of the assembly, and it is likely that the stability of such a copy will be several times lower than that of the original. And you are still very lucky if in such a converted Windows, spyware utilities are not installed by the same author of the assembly. I'll tell from personal experience, using a pirated system, I have always encountered problems: either the Internet does not work, or it gives an error when updating drivers and installing programs, in general, I cannot list all the examples. In general, if you want a stable and most important secure system Windiws 10, then install only the original. This is the most irreplaceable advantage of this method.

2. The second advantage is free activation, which we will carry out using a proven and safe activator KMS Auto Net. This activation method guarantees the stable operation of Windows 10, as if you were making it official, in a paid way. And it will give your system a lifetime activation key, with authentication and installation of all updates.

3. No disks are required, this is already an outdated age. We will install Windows 10 from a USB flash drive, it is as fast and convenient as possible.

Detailed video review:

The installation process will take place in three stages:

1. The first step is to enter the boot menu (Boot Menu). Depending on the motherboard, the call keys will be different. To select a key, see the table:

2. In the Boot Menu, select the desired flash drive and click "Enter".

3. During the installation process, you will need to enter a key. Enter this one: "NW6C2-QMPVW-D7KKK-3GKT6-VCFB2" if it doesn't work then download the full one archive with keys.

5. Accept the license terms.

6. Select the top installation type.

Hello friends, I want to highlight today's article on how to activate Windows 10. Not only will I describe in this article all known legal and effective ways activation, but I will also write about illegal ones, which a very large number of users now use. This is true, because no one wants to pay about 8 thousand rubles for one copy of Windows 10 Pro.

In the material, I will analyze how to activate Windows by phone, using a key, and also without a key. We will learn about programs that can activate the system, as well as other software, in a couple of clicks. Let's try to understand why Windows is not activated and much more. If the article is very large, then I will divide it into two parts.

Activating Windows with a key

The easiest way to activate Windows 10 is by entering your product key. IN boxed version this key is drawn on the box itself. On most laptops, it is glued to the back of the laptop. The next point is that the key is usually tied to the hardware, so it is unlikely to work on other devices, and on laptops it is sewn into the BIOS. This means that the key does not need to be entered, it is necessary to install the system of the required edition and it will activate itself.

If you have a Windows 10 key, then you can enter it as follows:

Open the system settings window by pressing the Win + I keys. Next, go to the "Update and Security" section. We go to the subsection "Activation" and on the right we find the parameter "Change product key".

In the same window, you can find out the edition of your system, for example, Windows 10 Home, and whether the system is activated or not.

Additional information about update 1607

Since about 2016, users who upgraded to "tens" from Windows 7 and 8 have a key binding not only to hardware, but also to account Microsoft.

Many already know that this solves problem situations with activation when replacing components and other nuances.

Windows 10 Digital License

There is a so-called digital license, which does not require entering a product key. When connected to the Internet, the system is activated automatically. This function available only to those users who have upgraded from a licensed version or are members Windows programs insider. Once this is done, the user will no longer drive the key, because it is already tied to the hardware, this is called a digital license.

In the Update and Security window, you can see how Windows was activated.

Many sites and forums write that you should not enter the key during digital activation. This means that the activation may fail, and the entered key will not work. Although this does not always happen.

I also suggest that you read the article from Microsoft, which describes activation solutions.

Activating Windows 10 by phone

If it is impossible to activate via the Internet, or some activation methods do not work, you can use the following method.

• Press the Win + R keys until the "Run" window appears.
• We enter the command slui 4.
• A country selection window should appear.
• The number you need to call will be displayed, there will be activation instructions, just in case you can write everything down.
• Upon receipt of the code, enter it in the required field and activate it.

By the way, some editions do not allow you to activate Windows by phone. In this case, a corresponding message will appear.

How to activate Windows 10 after changing hardware

This question is very important. If you are linked to a Microsoft account, then there will be no problems. That's all pies. Before changing the configuration, bind the key to the account in order to avoid problems.

Where to get a license key to activate Windows 10

The legal way is to buy a key. There are several ways to purchase it:

• Purchase through the store Windows PRO versions.
• Purchase of the boxed version.
• Buying a laptop or computer on which the key is already tied to the equipment. (The most expensive way).

From the store, you can easily upgrade to the Pro edition, but if you have any version other than "For one language". I have already encountered this myself and cannot update the top ten due to the fact that it costs OEM.

A dozen can also be bought on the official Microsoft website, although it costs 8,699 rubles there, so few people want to spend so much money, if there are cheaper methods, as well as free methods.

Buying a Windows 10 Product Key on eBay

Recently discovered an interesting way to activate the system. You need to install the desired version of the system, buy a key for about 200-300 rubles, enter and activate the system. Someone says that it is illegal, while others use this option and do not complain. I myself do not know how to relate to this, but I will tell you about the method.

We register on the eBay auction and enter “Windows 10 Pro” in the search bar. We have a large selection of products, the price of which varies greatly. But you need to take it from the seller with the highest rating and a lot of positive reviews.

Buy the key in a way convenient for you and wait for it to arrive in the mail. After receiving, enter it and enjoy a licensed copy.

How to activate Windows 10 without a key

Now let's start looking at options where we don't need a product key. Here we become a pirate, who we shouldn't become, but you can't change people.

Activating Windows 10 with KMS

The most popular Windows activation method is using a dedicated KMS activator. You can download it and activate clean Windows, or download some assembly where the activator will already be built in and do everything by itself.
