Official activation of windows 10

Any copy of the operating room Windows systems 10 needs activation. If you purchased a licensed version, then the activator will be a special key. If you use a pirated copy, you will have to resort to third-party software in the form of an activator or crack. Let's figure out how to properly activate Windows 10 in each situation.

The activation method that is suitable for your computer depends on how you installed the operating system:

• if you purchased a licensed product and just installed it on your PC or laptop, then you just need to enter the key;
• restoring the pre-installed OS on a laptop will not require re-activation if you are using exactly the same version of Windows 10 (bit size, build, etc.) In this case, you will receive a license without a key and activator;
• upgrading a licensed copy of Windows 7 or 8 to “ten” also does not require confirmation with a key;
• The pirated copy works fully during the trial period. After that, you need to activate it using KMS Auto or another similar program.

How to check your license

To find out if it is activated installed system, the standard will come to the rescue Windows application– “Parameters”. To do this, follow these steps:

1. Right-click on the Start icon on your desktop and select Settings.

1. Go to the "System" section.

1. Open the “About the system” subsection. Here you can see the version and build of your OS (Windows 10 Pro, 64-bit). Next, click on the button marked in the screenshot.

1. In the “Activation” subsection you will see the following message if your OS is activated with a key:

In PC settings, you can also change the product key using the marked button. This operation can only be performed under an administrator account.

Traditional method

Did you buy the boxed version or the digital key? Then all you have to do is enter it into the appropriate window in Windows 10. To do this, follow the instructions:

1. Open Settings by right-clicking on the Start icon.

1. Now open the Update & Security section.

1. In the left column, select the “Activation” subsection and click on the “Activate” button. In the window that appears, enter the existing key.

Via phone

Activating the OS over the phone is quite easy if you have the license key in hand. To perform the procedure you will need the command line and mobile phone. The advantage of this method is that you do not need to connect to the Internet, which can help in some cases (for example, problems installing a driver on a network card).

For the first or repeated activation via phone you must:

1. Open a command prompt with administrator rights. Do this via the Run window, cmd command and run with Ctrl + Shift + Enter.

1. In the command line, enter “slui 4” and press Enter. A menu will open on the screen where you need to specify your personal data. Next, call a paid or toll-free number.

1. Now you need to follow the instructions from the answering machine. Click on one if you are an individual, and “2” if we are talking about the corporate version. Now press “1” again to proceed to the activation procedure. You must enter each block of numbers one by one, as required by the operator. If everything is entered correctly, the answering machine will notify you about this. It will then begin dictating a verification code that must be entered into the marked fields. At the end of the procedure, click on “Activate”. If the entire procedure was completed correctly, you will receive an activated OS.

Be sure to check the success of the event through Windows settings as described above. In this way, you can permanently obtain a license before reinstalling the OS.

If you were unable to activate by phone, then you did something wrong. Check that the code dictated by the operator is entered correctly.

There is also a possibility of a hardware problem related to the computer ID. To fix it you need to do the following:

1. Go to "Device Manager". This can be done through the search bar. Enter the name in Russian or the command “devmgmt.msc”.

1. Open the “Network Adapters” subsection, right-click on your network card and select “Disable”. Do the same with the sound card.

1. Now perform the activation again, after which you can turn on the equipment again.

Reinstallation on laptop

If you purchased a laptop with a pre-installed operating system (OEM), then activation is available to you without entering a key. This is due to the fact that the license information is already “hardwired” into the BIOS or UEFI on the motherboard. You can restore the OS to its factory state without activation using the standard Recovery utility, which is available on the laptop’s hard drive. For example, Lenovo products have their own recovery menu:

After reinstallation, you will see a message in the “About System” window indicating that the OS has been activated. To find out about in a specific way recovery without reactivation for your laptop, you need to go to the manufacturer’s official website and read the help information.

Thus, you will not need to write the Windows 10 distribution onto a USB flash drive, and you will not need to manually enter the key.

Using activators

If we are talking about a pirated copy, then you can activate the OS using special utilities. Let's figure out how to get a license for free and forever.

The first program is KMSAuto. You can download and install it yourself.

Using KMSAuto Net you can activate the operating systems Windows 7, 8, 10 (Home/Professional/Insider Preview/Enterprice/Enterprice LTSB, etc.), package office programs Microsoft Office. rus/en versions and 32/64-bit systems are supported. Before unpacking the zip or rar archive with the utility, it is recommended to disable the standard Windows Defender:

1. Open "Windows Defender Security Center" through search.

1. Click on the marked button.

1. Open Security Settings.

1. Set Real-time Protection to Off.

Any antivirus has the ability to add software to exceptions/trusted programs. After you finish working with KMSAuto, you can remove it from the list or completely remove it from your computer. During the procedure, the Microsoft KMS service is replaced with a virtual server created on a PC. After the activator has managed to “deceive” the OS, it removes the server from the computer.

Now you can proceed to activation:

1. On the main screen of the activator, press the marked button.

1. At the bottom of the window you can see the status of the procedure.

1. At the end of the process you will see the following message:

If you are unable to activate in automatic mode, then use the instructions for manual mode:

1. Go to the "System" tab. To begin, click on the “Install KMS-Service” button.

1. Next, click on “Install Windows Key”.

1. After this you must remove KMS-Service. Now you need to click on “Create a task” so that the activator can carry out the procedure again after the license expires.

The second activation utility is Re-Loader Activator. The program is less known, but no less effective. Before using it, also disable your antivirus protection. After launching the application, you will be asked to agree to the rules:

Leave a checkmark next to Win and click on the “Activation” button:

After completing the procedure, restart your computer.

Results

If you are the owner of a licensed copy, then activating Windows 10 for you means entering the key in a special window or one phone call. If you don’t understand why you should buy an OS that can be quite expensive, then install one of the activators.

In both cases, you get a complete and functional operating system.

Video

We invite you to watch the video instructions. In it you will discover something new about activating the OS or learn how to do it yourself from scratch. The video is an addition to the main manual and clearly explains each step.

Windows 10 is a new version of the operating system from Microsoft. Having analyzed its capabilities, there is every reason to assume that it will be here for a long time, although frequent updates are expected. Due to its popularity and more comfortable use, its installation is relevant.
It is not necessary to contact computer support, because it can be activated on the Internet absolutely free. You need to reserve 20 minutes of free time and follow our recommendations. Now we will talk about how to activate Windows 10 and tell you what to do if there is no positive result.

Why do you need to activate Windows 10?

Some users are wondering: why activate the new Windows, because operating system somehow it works.

Frequently resetting the desktop background image and constantly popping up a window about a new version, of course, is not a reason for changes. But problems with personalization and regular automatic reboots after a couple of hours of operation make you think that maybe it’s time to update the system. Who knows, maybe the cunning Microsoft engineers will come up with something to irritate us even more. Therefore, the sooner you resolve the activation issue, the more relaxed your work with your favorite gadget will become.

How to activate Windows 10?

For the system to activate, you will need to use a digital license or enter a special 25-digit key.

It should be noted that if you are going to install licensed Windows, you will not need a key. This method is suitable for those who plan to update a licensed “seven” or “eight” for free, or have purchased a “ten” installation package in the Windows store. The system is activated automatically as soon as the system establishes a connection to the Internet.

The user can also purchase a key, which will need to be entered after the OS prompts. Activation will occur automatically during a connection to the World Wide Web. The same method is used to verify authentication during installation.

Entering a code is only required during the first installation of the product. With further updates, the Windows service, having remembered the code, will carry out the operation automatically.

How to activate Windows 10 by calling?

It happens that you do not have the Internet at hand or Microsoft servers fail due to severe overloads, you can activate the system over the phone. To do this you will need:

• hold down the key combination “Win ​​+ R”, type “slui 4” and press Enter;
• in the dialog box that appears, indicate your country and select “Next”;
• now make a call to the number offered by the system and strictly follow the commands of the answering machine (immediately get ready to write down recommendations, armed with a pen and a piece of paper);
• Enter the dictated code and click on the “Windows Activation” button.
  You see, it’s quite easy and simple.

Purchasing a key for Windows 10

Do you have a licensed key for older operating systems, such as XP? Unfortunately, it is not suitable for activating Windows 10. Therefore, you need to purchase a “fresh” 25-digit digital code.

Methods of obtaining:

• purchasing a licensed OS on disk in a store;
• purchase on the official Microsoft OS website, but only in digital format;
• use of volume license/MSDN subscription features;
• ordering a key to activate the system.

It should be noted that for Windows connections 10, you will have to pay quite a bit of money.

Options for activating Windows 10 without a key

If you don’t have extra funds to buy a key, you can use the old fashioned method, which involves piracy. Of course, the license agreement does not provide for such an option for installing the system, and the law strictly prohibits such manipulations. Therefore, important information for you - you will act at your own peril and risk.

You will need to use an activator program, which is quite easy to find. Be very careful, because often downloading from an unverified resource can infect your device with a malicious virus, which will lead to the loss of data and passwords. There have been cases where users entered their bank cards and lost their savings.

What programs are suitable for activating Windows 10?

If you download good program To activate the tenth version of Windows, you can easily bypass Microsoft’s security mechanism and make your OS smooth and obedient. A correctly chosen program will not slow down the system and carry constantly pop-up advertisements.

We can recommend a truly powerful application, KMSAuto Net, which is regularly improved by its developers with frequent updates. In addition, she offers real way activation of Windows 10 - securely, free and forever (or at least until the product manufacturer learns to block it). The creator of the Ratiborus activator regularly maintains a special topic on the forum that will help explain to visitors the various capabilities of the program and tell about his new developments.

KMS activator for Windows 10

This activator program can easily be called the most the best tool to update the OS.
Advantages:

• developer experience and product lifespan;
• simplicity for ordinary users;
• fast work.

Activating the “ten” with the KMSAuto program can be done effortlessly. Sometimes it will need the NET Framework to work properly, but it already exists on many computers.

Program features:

• quite easy to use, no special knowledge is needed to understand how it works;
• for advanced users who prefer fine-tuning, there is a special mode;
• free;
• there is an activation check (perhaps everything is fine with you, but you don’t think twice about it);
• suitable for many OS versions - from Vista to 10, and also supports Windows server versions;
• can at the same time activate the latest versions of MS Office;
• due to the rich toolkit, it allows you to bypass the manufacturer’s protective mechanism, selecting the most suitable ones for you optimal options(default).
• In addition, it comes with detailed instructions, in particular in Russian, which will tell users all the intricacies of working with individual modes and other nuances of activation.

Step-by-step instructions for using KMSAuto Net:

A few words about the advanced mode

When you go to the “About” tab and select “Professional Mode”, several tabs for special settings will become available.

They concern those who are interested in certain nuances of IP settings.

By using the “Advanced” tab, you can save the activation information and try the usual setup.

The “Utilities” tab allows you to use other tools as part of activation.

Other activators

In addition to KMS, there are other utilities on the Internet. For example, Re-Loader Activator, which can activate Office. The program is also easy to use. But the translation into Russian is not very good.

What to do if Windows 10 does not activate?

It happens that the system worked at first, and then for some reason crashed. If you have a licensed copy, contact Microsoft support or read the list of possible errors.

If you installed the activator, then complete the task again. If blocked by an antivirus, add the activator files and service to the exception or simply disable the antivirus during installation.

Windows 10, a popular operating system from Microsoft, requires activation from the user after installation, which is quite complex and multi-step compared to most proprietary programs. In particular, activation can be done through a phone call. Let's look at how to do this.

How to find out the activation key

First of all, to activate the system we need an activation key. As a rule, it is written on the back of the system disk or sent to you in an email during installation. If you don’t know it, it is recommended to use a simple program that analyzes the system and gives the user a key “hardwired” into it - for example, using the ShowKeyPlus utility. How to use it? Nothing complicated! Just run it and the utility itself will find all the data you need. ShowKeyPlus is free and open source. You can download it.

However, since the system is not activated, it means that you may not have a key at all. In this case, you must first obtain it from Microsoft and only then continue with activation.

Activating Windows 10 by phone - step-by-step instructions

Once you have found out the key, you can begin the main part of the work - activation. To do this, you need to have a phone, a console, administrator rights and, preferably, a piece of paper with a pen in order to successfully write down the number dictated by the robot.

1. First you need to go to the console. This is done by several in different ways: you can click “Run” (Win + R) and enter cmd in the window that opens, you can right-click on the “Start” button and select “Command Prompt (Administrator)” from the menu that opens.
2. In the console you need to type slmgr.vbs /upk. This way we will delete the old key. After this you need to enter the command slmgr.vbs /ipk<ваш ключ>, and enter the key without spaces, through hyphens, as it was originally displayed. To activate the system in the standard way, you can enter slmgr.vbs /ato. But this is not our case, and to activate via phone you will need another command.
3. A message will appear indicating that the key has been successfully installed into the system. Now you can move on to the next step: in the same command line you need to type the command slui 4. It will open the phone activation menu. In the menu that appears, you need to indicate the country in which you live, and after that a window will appear with the data necessary for activation.
4. All that remains is to make a phone call. To a toll free number. Don’t worry: you won’t have to communicate with people, the activation is carried out by a robot, and all you have to do is press the buttons according to the given script:
   • press 1 if you are a private person;
   • press 1 if you want to activate Windows 10;
   • During the briefing, you can press # if you do not want to listen to it;
   • enter the first block of numbers from the activation window; then the second; then the third, and so on;
   • if everything went well, the robot will report that the data has been received.
5. The robot will begin to dictate the numbers of the confirmation code. If you type slower than you write, then this is where a piece of paper and a pen will come in handy. Carefully record the code and enter it in the appropriate field in the activation window (it’s called “Enter confirmation code...”).
6. "Ready!" - the system will happily report. That's it, Windows 10 is activated and you can do whatever you want with it.

Is this method safe?

In short, yes, it is safe. No more dangerous than any other type of activation. Of course, it is advisable to comply simple technique security: do not show the key or confirmation code to anyone, do not perform activation in public places, do not record calls or delete the recording immediately after activation. But objectively, the worst thing that can happen is that your activation code will leak onto the Internet and will be used to activate pirated versions of the system. If used for a long time, this can lead to the code being blocked and the need to obtain it again - this is not the easiest procedure. But it is impossible to gain any access to personal data or files on the computer through the activation code.

Don't put off this decision for too long important issue: “How to properly activate the new Windows 10?” Otherwise, the user will receive at least working system, but limited in several parameters. A system notification that it is activated will constantly be displayed before the eyes of the computer owner.

And the user will not be able to change the “Personalization” parameters at his discretion, but otherwise the new operating system with index 10, oddly enough, will be quite functional. This article describes all the solutions to issues related to emerging difficulties, such as the problem with subsequent activation of installed Windows 10, and also details methods on how to activate Windows 10 for free.

Problems

In practice, most often users encountered the following problems, due to which computers with installed Windows 10 system activation:

1. Windows 10 cannot be activated due to a discrepancy between the OS previously running on the PC

This reason is indicated by the display of error “0xC004F061”. Often, a PC was previously running an early OS modification that did not meet the requirements. Windows 10 is automatically activated after updating only the official versions of Windows 7 or 8. And if users of licensed “Sevens” and “Eights” were unable to successfully complete the procedure, then the partitions were probably formatted hard drive computer without a preliminary upgrade process to “Ten” in order to have time to link the equipment to the new system. Such PC owners are recommended to, if possible, roll back to the initial modification of Windows.

2 Unofficial modification

If the user has installed an unlicensed copy of Windows 10 on his computer, Microsoft will not confirm the key entry. In this case, the owner of such a pirated copy must enter the command line, where he must type as a system administrator:

slmgr /ipk W269N-WFGWX-YVC9B-4J6C9-T83GX

slmgr /skms kms.xspace.in

Next, by executing the specified commands, “Ten” is activated, and the user can normally operate the OS. But in the case when such activation fails, it is recommended to use an activator. This material below will provide descriptions of guidelines for the use of currently operating activators.

3. Changing PC components

After updating to new system for specific electronic equipment computer a Windows license is reserved for the user. If you replace some computer components, Windows 10 will not activate.

Activation methods:

1. Using a key

This is the easiest method. If you have purchased Windows 10

or when purchasing, for example, a PC with Ten already preinstalled,

then the user has an external system drive with a key or it is registered on the computer case.

To activate, the lucky owner of the key only needs to do the following few sequential steps:

2. Using an activator

Many users will be pleased that by now a huge number of different activators have already been released, with the use of which you can quickly complete the task. The computer owner only needs to decide whether he should use them, since a significant number of such special applications contain viral content and utilities.

But there are also repeatedly tested programs that do not contain malicious applications, but they are often filled with various so-called “garbage”, which are completely unnecessary utilities. For example, a similar activator is shown in the image below:

Due to the above problems that arise when using activators, it is recommended to use only the utilities presented in this manual that have already been analyzed for cleanliness.

Activator – “Re-Loader Activator”

It is easy to use. In addition to the main task, it also copes well with activating Microsoft Office. In order to ensure the functioning of the application, it is necessary to install “Net Framework 4.5”.

The algorithm of actions consists of the following steps:

"KMSAuto Lite"

This utility is deservedly very popular among new users of Windows 10. Similarly, like the previous one, it very simply and successfully copes with the problem of activating the OS and Office.

You need to do the following:

For users who upgraded their system to Windows 10 for free

If the computer owner has made the transition from Windows 7 or 8, then the following sequential steps must be taken:

1. Click “Start” and enter the “Settings” section;
2. Then click “Update and Security”;
3. Next, go to the “Activation” tab and if the computer is connected to the World Wide Web, then after this the procedure will be performed automatically.

Note: It often happens that Microsoft servers cannot cope with the influx, so the only thing recommended is to be patient and, after a period of time, perform all the above steps again.

Using Skype

This method requires a significant amount of time from the user, but turns the tenth OS of the computer owner into the official one forever.

The following actions are required:

Several years ago, Microsoft began distributing a new version of Windows in an unusual way: via .iso images that were installed without activation codes and license confirmation. But people who have installed Windows 10 are often faced with an obsessive requirement to activate the system, that is, to enter the license code purchased from Microsoft. Let's consider whether activation is required and how to perform it.

Do I need to activate Windows 10

Many users have a logical question: is activation necessary at all? The system can be used without it, and no restrictions are visible at first glance. So maybe you don’t need to activate Windows 10?

However, in a non-activated OS, some functions are blocked. Not the most important ones - just personalization settings, but until you activate the system, they cannot be changed.

This means that you won’t be able to put a photo of your favorite cat on your desktop or make larger icons.

In addition, there is an annoying activation reminder on the screen all the time, which, although it does not impose any restrictions, is great on the nerves.

So if you don’t care whether personalization works in the system, you can safely remain on non-activated Windows 10. This will not prevent you from working with the system.

But if the activation reminder and personalization restrictions cause you inconvenience, then the system will have to be activated.

Activation methods

Microsoft developers have invested several things in Windows 10 in various ways activations:

• during installation;
• through Windows settings;
• using the command line;
• by phone.

There are also several types of licenses, each for its own needs:

• OEM activation is a license type that is typically used on new computers. The system is activated by the computer builder, and a license code is provided to the buyer along with the device. If you've ever bought a computer with Windows pre-installed, then most likely you have an OEM license. In this case, the system is activated without using the Internet. The main disadvantage of this approach is that it is tied to a computer: if you change any components in it (most often the motherboard), the license may be lost;
• KMS activation is used by companies. This type of license assumes the presence of a server dedicated to managing many keys (up to several thousand) within the corporation. For private users this method is useless;
• FFP, or Retail, is a “boxed” version of the system purchased by the user directly from Microsoft (from disk or via the network). In the case of Windows 10, you usually only buy a key, since the non-activated image is available for free. It is usually expensive, but it is not tied to hardware. There is also a MAK option, which involves installing a copy of the system several times on different computers;
• Digital Entitlement (digital binding) is a method used on devices that have been updated for free from licensed Windows 7 or 8 to version 10. It is tied to a Microsoft account and, in parallel, to a specific computer. In fact, it is a special case of an OEM license.

Most often, Windows 10 is activated using an OEM or Retail license

Thus, if you want to get registration forever, on any computer, regardless of hardware configuration, then your choice is Retail, and if you don’t want to bother with activation, then a computer with a pre-installed OEM license is best. In any case, little depends on the user himself: the system you have is already “tailored” for one or another type of license (unless, of course, it is pirated).

Most often, the system is activated as Retail or OEM, depending on the method in which the user received Windows.

Activation via computer settings

The easiest way to activate is through the computer settings. To do this, you will need a key and an Internet connection.

This method is the default and the simplest of all available. However, it may have problems if there is no network connection. Then other methods come to the rescue, in particular, a telephone call.

Activation via command line

This method involves running the activation script directly. Open a command prompt console and enter the commands listed below. You will also need a key and internet access.

Video: activation via command line

Activation via phone

In addition to activation via the Internet, Windows 10 has the ability to register a key using phone call. This can be done through Windows settings or through the command line console. Let's look at activation using a phone using the console as an example.

What to do after replacing the motherboard

As explained above, in some cases, Windows 10 activation is tied to the computer’s motherboard and may be lost when it is replaced. This problem is relevant only for users whose system is activated using OEM or digital binding. Users who purchased the system “in a box” do not encounter it.

Previously, in such cases, you had to contact technical support. Fortunately, Microsoft quickly fixed the problem and in the next update added a feature that allows you to restore activation using standard means through a Microsoft account.

Microsoft points out that problems may arise when restoring activation, and explains in what situations this may happen:

• you are trying to reactivate an unlicensed copy or a system that was not initially activated;
• the device on which reactivation occurs is too different from the original one (in other words, completely different);
• the wrong one is activated Windows version, which was installed initially;
• the number of possible activations has been exceeded;
• the system has several administrator accounts, one of which has already been reactivated;
• the system has a commercial license that belongs to the organization.

If none of the above conditions are met, and it was not possible to reactivate the system, then you need to contact Microsoft technical support.

Activation after reinstallation

In the case of an OEM license, activation upon reinstalling Windows 10 occurs automatically due to binding to the equipment. You do not need to enter any keys during reinstallation.

Sometimes the license is not restored immediately. In this case, you need to wait for 24 hours and, if activation fails, contact Microsoft technical support.

With the Retail version everything is a little more complicated.

Before reinstalling, the user must keep the license key that was issued to him when he purchased Windows. If the system was purchased “in a box”, then the key is usually written on it inside; When purchasing through the official online store, Microsoft sends the key via the network.

This key must be entered when reinstalling the system. In this case, activation will work immediately. Just keep in mind: until you delete the previous instance of Windows activated by this key, you will not be able to use it.

Also, until the system is removed from one computer, it will not be possible to activate it on another with the same key.

If activation errors appear during reinstallation, then you are either installing a different version of the system or entered the wrong key. Continue the installation without activation, and then activate the system with the existing key using different options registration. If that doesn't work, contact Microsoft technical support.

What to do if an activation reminder suddenly appears

It happens that the system has been activated for a long time, nothing has changed on the computer, but suddenly a reminder appears about the need for activation. The most likely reason for this is the installation of third-party software that has damaged the license.

It is advisable to remember your activation key. However, if you have forgotten it, then the free ShowKeyPlus utility, which you can download, will tell the user which key is installed on the system the first time it is launched.

Go to “Start - Settings - Update and Security - Activation” and select “Change product code”, and then enter the key in the window that opens. If this does not help, try to force reactivation by typing the following commands in the command line console:

vbs –rearm - starts re-activation, requires a reboot and key entry;

lmgr.vbs /ato - forced license check, used if the previous command did not help;

slmgr.vbs/ipk<ключ>- manual key replacement if the first two options did not help.

If you cannot fix the problem manually, you should contact Microsoft technical support.

The exception is pirated systems: it is obvious that problems with activation are quite natural in them.

Problems and errors when activating Windows 10

Although the activation system of the “ten” is the most advanced in the entire Windows line, sometimes problems and errors arise in it too. We have already considered some of them (loss of activation when replacing the motherboard, nuances during reinstallation, failed activation). Now let's talk about more general errors that arise directly during the activation process.

Product key is locked

There may be several reasons for this error, but the most common are two:

• you are trying to install “clean” Windows 10 without first updating and are using an old key;
• activation servers are busy.

The first option should not exist after update 1511. Check Windows updates 10 and try activating again. If it doesn't work, contact Microsoft.

In the second case, all you need to do is wait for a while. When the servers are unloaded, activation will be successful.

License is invalid

There are a number of errors that are similar to each other and appear for similar reasons:

• error 0xC004F034: license could not be obtained or is invalid;
• error 0xC004F050: the entered product key is invalid;
• error 0xC004E016: Error installing product key.

Most often they occur if the key you entered is pirated. Another option is that you are trying to activate Windows with the key for the wrong version (for example, the Pro version with the key for Home). In this case, you need to download and install the system image that matches your license.

Errors when checking license

• error 0xC004C4AE: the scan service detected broken Windows binaries;
• error 0xC004E003: Licensing service software reported that an error occurred while checking the license.

These errors most often mean that you are trying to upgrade to Windows 10 using an unlicensed copy. If this is not the case, then the error was most likely caused by some third-party software. It is recommended to roll back the system to a time when this software was not in it.

Network problem during activation

This error appears if the system fails to activate itself via the network, and means that the computer is not connected to the Internet. It is recommended to check the drivers network cards and firewall settings: they may prevent the activation program from accessing the network.

If you didn’t have Internet on your computer initially, then your solution is activation by phone.

Windows activation check

The activation status of the device, license type and system version can be checked by following the already familiar path: “Start - Settings - Update and Security - Activation”. This is where this data should be stored.

Activation can also be checked using the command line: the command slmgr /xpr should display a dialog box with the activation status.

Checking activation through the console is one of the ways to find out the status and type of Windows license

Video: how to check your Windows license

Activation of Windows 10 is optional, and the user can work with the system without it. However, the variety of ways in which this OS is activated makes it easy to register it, and after reinstalling or changing equipment, restore the license without any problems. If errors occur, Microsoft technical support is always available and will provide you with qualified assistance.
