Set up Windows 10 System Restore. Windows System Restore

The Windows 10 operating system is very easy to use. Any user will be able to understand it and even independently cope with certain problems. Unfortunately, sometimes there are too many errors, and they cause damage to system files or lead to other serious problems. The Windows recovery option will help fix them.

Reasons to Use Windows Recovery

The main reason is the failure of the operating system to boot. But in itself, this malfunction can occur due to various factors. Let's analyze the most common:

  • file damage by viruses - if OS files are damaged by a virus attack, the system may malfunction or not boot at all. Therefore, it is necessary to restore these files for normal operation, since there is no other way to solve the problem;
  • incorrectly installed update - if an error occurred during the update or some of the files were installed incorrectly for another reason, then instead of completely reinstalling the broken operating system, its restoration will also help;
  • hard drive damage - the main thing is to find out what the problem is. If the disk has physical damage, then you can not do without replacing it. If the problem is exactly how it works with data or any OS boot settings - recovery can help;
  • other changes to the registry or system files - in general, almost any changes to the system can lead to errors in its operation: from minor to critical.

Restoring directly from the Windows 10 system itself

It is conditionally possible to divide the recovery methods into those used before the system itself boots and those that are used already when the system is booted. Let's start with a situation where Windows boots correctly and you have the ability to use programs after it starts.

Using a restore point to roll back the system

First, you need to configure the system protection itself directly so that it is possible to create and store restore points. To do this, follow these steps:

Now you can proceed to create a restore point:

When the point is created, you need to figure out how to return the system to the state at the time of its creation, that is, roll back to the restore point:


Another way to access restore points is in the diagnostics menu, which is opened through the "Settings" of Windows 10 (Win I). This menu works in exactly the same way.

You can also use restore points through advanced system diagnostic options

Resetting the operating system to factory settings

Windows 10 has another recovery method. Instead of a complete reinstallation, it is possible to simply reset the system to its original state. Some programs will become inoperative as all registry entries are updated. Save the necessary data and programs before resetting. The process of returning the system to its original form is performed as follows:

  1. Press the Win+I keyboard shortcut to open OS settings. There, select the "Update and Security" tab and go to the system recovery section.

    In Windows Settings, open the "Update and Security" section

  2. Press the "Start" button to start recovery.

    Press the "Start" key under "Reset this PC"

  3. You will be prompted to save files. If you click "Remove everything", the hard drive will be completely wiped out. Be careful when choosing.
  4. Regardless of the choice, the next window will display information about the reset that will be performed. Examine it and, if everything suits you, press the "Reset" key.

    Review the reset information and click "Reset"

  5. Wait until the end of the process. It may take up to an hour depending on the options you select. The computer will restart several times during the procedure.

Restoring system data through "File History"

"File History" - the ability to restore damaged or deleted files for some time. It can be very useful if you need to get back lost videos, music, photos or documents. As with restore points, this option must be properly configured before applying:


Thus, you will be able to recover files, unless, of course, the disk has been subject to a complete data wipe. Now let's figure out how to recover a lost file:

Ways to recover without logging in

If the operating system does not boot, then it is more difficult to restore it. However, acting strictly according to the instructions, and here you can cope without problems.

System recovery via BIOS using a boot drive

Using a boot drive, you can start system recovery through the BIOS, that is, before Windows 10 boots. But first, you need to create such a drive:


Nothing more is required of you. The boot drive will be created, and you can proceed directly to system recovery. First you need to open the BIOS. This is done by pressing different keys when turning on the computer, which depend on the device model:

  • Acer - most often, the buttons to enter the BIOS from this company are the F2 or Delete keys. Older models used whole keyboard shortcuts, such as Ctrl+Alt+Escape;
  • Asus - F2 almost always works, especially on laptops. Delete is used much less often;
  • Dell - also uses the F2 key on modern devices. On older models, it's better to just look for instructions on the screen, since the combinations can be very different;
  • HP - laptops and computers of this company enter the BIOS by pressing Escape and F10. Older models did this using the F1, F2, F6, F11 keys. On tablets, F10 or F12 is usually used;
  • Lenovo, Sony, Toshiba - like many other modern companies, use the F2 key. This has become practically the standard for entering the BIOS.

If you did not find your model and could not open the BIOS, carefully study the inscriptions that appear when you turn on the device. One of them will indicate the desired button.

Once you have entered the BIOS, do the following:

  1. Find First Boot Device. Depending on the BIOS version, it can be located in different subsections. Select your OS drive as the boot device and restart your computer after saving the changes.

    Set the desired device to boot as a priority

  2. Installation will begin. Check the language and if everything is correct, click "Next".

    Choose your language at the beginning of the installation

  3. Go to System Restore.

    Click "System Restore"

  4. The recovery menu will open. Select the "Diagnostics" button.

    Open the system diagnostics menu in this window

  5. Go to advanced options.

    Go to advanced diagnostic menu options

  6. If you have created a system restore point before, select Restore Windows using a restore point. Otherwise, go to "Startup Repair".

    Select "Startup Repair" in advanced options to fix operating system errors

  7. The automatic verification and correction of boot files will begin. This process can take up to 30 minutes, after which Windows 10 should boot without problems.

Create a boot disk from an image

If you still need a boot disk for system recovery, and not a flash drive, then you can create it using the ISO image obtained earlier, or use a ready-made installation disk with the same version of the OS. Creating a boot disk is done as follows:


In case the recovery fails, you can always simply reinstall the operating system using the same disk.

System restore via command line

An effective tool for solving the problem with loading the OS is the command line. You can also open it through the diagnostics menu, which was opened using the boot drive:


Another way would require defining the partition name:

  1. To find out the correct value, enter the diskpart and list disk commands. You will be presented with a list of all your drives.
  2. You can determine the desired disk by its volume. Enter the disk 0 command (where 0 is the number of the required disk).

    Enter the specified sequence of commands in order to find out the number of your disk

  3. Once the disk is selected, use the detail disk command to obtain the required information. You will be shown all partitions on the disk.
  4. Find the area in which the operating system is installed and remember the letter designation.

    Use the partition name you learned from the bcdboot x:\windows command

In addition to these, there are a number of other commands that may be useful:


Just try entering these commands one by one: one of them will solve your problem.

Recovery error fix

When trying to restore the system, an error with the code 0x80070091 may occur. Usually it is accompanied by information that the recovery was not completed. This problem occurs because of an error with the WindowsApps folder. Do the following:


Windows Activation Key Recovery

The OS activation key is usually written on the device itself. But if a special sticker with a key has worn out over time, you can also recognize it from the system itself. To do this, the easiest way is to use a special program:


If you need to find out the key before activating the system, then you can not do without contacting the place of purchase or official Microsoft support.

Set the desired screen resolution

Sometimes when restoring the operating system, the screen resolution may fly off. In this case, it should be returned:

Password recovery in Windows 10

If you have forgotten your password to enter the operating system, it is worth recovering it. You can request a password reset for your account on the official website:

It is worth being prepared for any problems with the computer. Knowing how to restore your system in case of problems will help you save your data and continue working on your device without reinstalling Windows.

If Windows 10 suddenly suffered a critical failure and stopped loading, the most optimal way out of this situation may be to roll it back to a restore point. Even if there is a system backup created using backup software on a non-system partition, it will be of little use if there is no boot disk with the corresponding program at hand.

Restoring the operating system by returning to the initial settings - with the preservation of user files, but with the loss of installed programs and system settings - is too radical a step to take only after attempts to roll back to a restore point have failed.

How to roll back Windows 10 to a restore point if the computer does not boot?

Recovery environment

As in the previous two versions of the platform, for resuscitation of Windows 10 a special recovery environment is provided, implemented in the form of a menu for selecting various actions on a blue screen background.


In fact, this environment is an analogue of the menu for additional boot methods, which is familiar to many who have encountered problems starting Windows 7. This menu in the seventh version of the system is called up when the computer boots by pressing the F8 key. Among the tools of the Windows 10 recovery environment, there is also the ability to roll back the system.

So, we have a computer with the system protection function enabled, which provides for the possibility of rolling back to one of the restore points in case of unwanted changes. The Windows 10 protection feature is active by default, and if no one intentionally canceled it, the system can be returned to the state captured in one of the restore points. Those should be created, if not sometime manually by the user, then at least by some software automatically.

How to get into the recovery environment?

If the computer is still able to boot, you can get into this environment by holding down the Shift key and clicking the system restart button.

In a situation where the computer does not boot at all, you can try to get into the recovery environment by holding down the Shift + F8 keys while the system boots. But achieving the desired goal will not be easy. Few have time to press these keys at the right moment due to the reduced boot time of the latest versions of Windows. As soon as the computer starts to boot, you need to quickly press the Shift key, and then frantically fiddle with the F8 key. After training, perhaps the work of some will be rewarded.

It is much easier to enter this environment either through the installation disk or using a specially created recovery disk.

Below we will consider both of these options and roll back the "dozens" to the restore point.

Using the Windows 10 installation disc

It doesn’t matter which installation DVD (or flash drive) is on hand - with the same edition of Windows 10 that is installed on the computer, or with another one, in any of these cases, the issue with access to the recovery environment has been resolved. Moreover, for these purposes, you can use the Windows 8.1 installation disc or even the Insider Preview test edition, which is available for free on the Microsoft website.


Insert the installation DVD of either Windows 8.1 or Windows 10 into your computer's drive, or connect a bootable USB flash drive if the distribution is written to it. Set the BIOS to boot from the appropriate media. Click "Next" on the first window of the system installer.

Select "System Restore" at the bottom of the window.


We will see the same recovery environment, in the menu of which you need to select one or another action. We need a diagnostic section.


Click "Advanced Options".



Select Windows 10 if, as in my case, the computer has two operating systems.

The process of rolling back the system to the restore point will start. Click "Next".


In the window for selecting recovery points, you need to check the option to show other points. Then we will have the opportunity to choose a suitable date - not too old to restore Windows to the most up-to-date state, but not too fresh when the problems may have already existed. Select the best point and click "Next".


Click "Finish".


We confirm the decision to roll back the system.


At the end of the process, reboot.


Not every system rollback process to a restore point can complete successfully. But I was lucky - everything went very well. Welcome to the restored system.

Create a Windows 10 recovery drive

If you don’t have an installation disk with system versions 8.1 or 10 at hand, you can’t do without involving a second computer device in solving the problem. And instead of waiting for the distribution image to be downloaded from the Internet, it’s easier to create a Windows 10 recovery disk using its regular tools. Naturally, for this it is necessary that the same Windows 10 be installed on the second computer device. In general, you need to take care of the presence of such a disk in advance. So the resuscitation disk, recorded on a USB flash drive, will always be with you in the wings if there are problems with loading the computer.

To create a recovery disk, go to the control panel. The shortest way to it is to call the context menu on the Start button.


At the top of the control panel window (on the right) is a search field. Write in it a key query to search for the recovery partition and select this partition.


We need the first function - "Create a recovery disk".



The system will warn that all existing data on the flash drive will be destroyed. Click "Create".


The recovery disk is ready.


Now enable the BIOS to boot from the desired media - from a USB flash drive. After loading, you will see the same recovery environment designed to resuscitate the operating system. Further steps will be exactly the same as in the previous case.

When can't you roll back Windows 10 to a restore point?

As already mentioned, the Windows rollback process may not always complete successfully, and this applies not only to the situation involving the recovery environment, but also when it comes to the normal launch of this process in the system properties window. If viruses damage important restore point files, most likely, the only way out of the situation may be, if not reinstalling the system, then at least restoring it with the loss of all settings and programs.

Sometimes it will not be possible to successfully roll back the operating system using the recovery environment due to the cut out of the recovery functionality itself. And this, by the way, is one of the reasons why you should not use artisanal Windows builds. Often the latter are designed only for installing Windows from scratch, without the possibility of recovery. The system restore functionality is cut by the assemblers, allegedly for the purpose of optimization. In this case, it will not always be possible to reanimate the operating room even with the help of third-party Live disks. But even in the case of a pirated assembly of Windows with truncated functionality, various kinds of problems can be foreseen by stocking up in advance with a system backup and bootable media using third-party backup programs.

List of keyboard shortcuts for restoring laptops to factory settings

For most laptops, the operating system and drivers are in a special hidden section and a disk is not needed at all to reinstall. It is enough to press a key at boot to enter the system recovery menu. I propose to compile a list of hotkeys for laptop mods, this will help many.

  • Acer Alt+F10(pre-enter the BIOS of the laptop, and enable the D2D Recovery function)
  • HP pavilion; LG - F10, F11
  • Packard Bell-F10
  • Dell Inspiron- as soon as the dell.com splash screen appears, you need to click Ctrl+F11
  • Dell XPS: F8 or F9.
  • ASUS- as soon as the ASUS splash screen appears, you need to press F9
  • Sony vaio- F10 or button ASSIST
  • Fujitsu-Siemens-F8
  • Rover- press and hold when turning on alt
  • LG-F11 while loading. The LG Recovery Center window should open.
  • Samsung-F4
  • Lenovo Thinkpad: F11.
  • MSI-F3.
  • Toshiba-F8.
  • Packard Bell-F10.

Complete description of Acer eRecovery recovery

Before the recovery procedure, please note that the Disk-to-Disk (D2D) function is enabled in the BIOS, for those who have it, enable the Quick Boot function (display the display of the OEM logo), or better, just return the BIOS settings to default (Exit tab Load Default Setup).

There is a hidden partition on the laptop hard drive for this purpose. If it was possible to remove it, then you will have to contact the service center.
If the hidden partition is not deleted, then booting from it and restoring the OS, we find along the way that all the information accumulated by the user has disappeared. Therefore, before the recovery procedure, important data must be saved on another medium.

Do some laptops come with a disc? Usually it is called "Reanimator" or something like that. If you install the system using this resuscitator, then the hidden partition with the Recovery utility should be restored, but when using this disk, all data from the screw will be lost, because the reanimator formats everything clean.

If you have reinstalled the system, then the Alt + f10 combination will not work. If you installed another HDD, now the function of the system restore key does not work? Since the recovery takes place from a hidden partition of the hard drive, and this partition is not on the new hard drive.

How to restore the system on a Lenovo laptop?

We offer you a brief instruction on restoring the operating system in Lenovo IdeaPad laptops to the "factory" state. Why might this be needed? Well, firstly, all users sooner or later have a desire to start from scratch. Secondly, your system may have a serious failure or it may be attacked by a virus, after which the OS stops loading. You need to understand that bringing the laptop to the form “like from a store” will erase all your data from your hard drive, so all important information must be copied somewhere before recovery.

If everything is ready and the data is safe, you can proceed. A program called Lenovo OneKey Rescue System will help us. It is installed on all Lenovo IdeaPad laptops (but not ThinkPads), and makes part of the hard drive invisible to the user, and stores the operating system there as it came from the factory. To start the recovery process, you must first turn off the laptop. And then turn it on again, but not with the standard button, but with the OneKey Rescue key. It is usually marked with a curved arrow and can be found on all IdeaPad laptops. On the IdeaPad Y460, the button looks like this:

Press the button and wait for the recovery shell to load.

As you can see, in the OneKey system, you can even check the hard drive for viruses. Moreover, you can create your own image of the system and all data, and in case of problems, recover from it. But now we will show how to restore the "factory" image of the system. To do this, select the OneKey Recovery item.

In the menu that opens, leave the choice "Restore from original backup".

After that, the system will ask you twice if you are sure. Think well, because, I repeat, all data from the laptop will be deleted!

Here you can watch the recovery process. It will take 10-15 minutes, after which the program itself will prompt you to reboot. Congratulations, your laptop is brought to the state of "like from the store" 🙂 Note that along with a fresh copy of Windows, you received all the installed Lenovo drivers and programs.

P.S. And don't forget that restoring the system to factory settings (to those when you got a new laptop out of the box) you format everything!

While running Windows 10, even despite regular updates and cleaning, bugs, freezes, hardware or system failures occur. Not in all cases, the only way to restore the system will be to reinstall it and completely format the local drives. Use programs to recover the password, registry, bootloader, system and Dll files in Windows 10.

In such cases, to return the operating system to working capacity, special disks or programs are used that are designed specifically to restore the system or files responsible for its smooth operation.

How to restore Windows 10 with programs:

Method 1: Windows 10 file recovery software

In cases where files have been deleted and it is no longer possible to restore them using standard Windows 10 tools, use Hetman Partition Recovery.

For this:

  • Download, install and run it. Check out the features of the program and step by step instructions.
  • By default, the user will be prompted to use File recovery wizard. Click the button "Further" and the program will prompt you to select the drive from which you want to recover files.
  • Double click on the drive you want to recover files from and select the type of analysis. Specify "Full analysis" and wait for the disk scanning process to complete.
  • After the scanning process is completed, you will be provided with recovery files. Select the ones you want and click the button "Reestablish".
  • Choose one of the suggested ways to save files. Do not save files to the drive from which they were deleted - they can be overwritten.

Method 2: Programs for recovering hard disk partitions

Methods for recovering hard disk partitions depend on the health of the system, let's look at the main cases:

Restore non-system hard drive partition

For this:


Restore the system partition of the hard drive

If the system partition is lost, it is impossible to boot the computer.

Restore the system partition of the hard drive using LiveCD

If it is not possible to connect a hard drive with a lost or damaged system partition to another computer, you can restore such a partition by starting the computer using LiveCD, an alternative portable version of the operating system.

For this:

  • Find and download the LiveCD that suits you to a CD/DVD or USB stick
  • Connect the LiveCD to your computer and turn it on. The computer will automatically boot from the LiveCD.
  • Copy the files from the system partition to another storage medium (often an external hard drive).

Method 3: Windows 10 DLL Recovery Programs

DLL errors in Windows can be caused by various reasons. This includes the removal or damage of one or another file of the library, the occurrence of a problem with the registry of the operating system, malicious software (viruses), hardware failures, or the presence of bad sectors on the hard drive.

There are different ways to recover DLL files, one of which is DLL recovery software. With the help of such programs, you can repair damaged DLL files or install missing ones.

sfc /scannow

To use it:


How to restore Windows 10 system files

Method 4: Programs for repairing the Windows 10 registry

To access and work with the Windows registry, there is a lot of software. With the help of such programs, you can find and fix registry errors. They typically scan the registry for invalid file paths and types, incorrect user controls, obsolete entries, invalid fonts, obsolete start menu items, unused file extensions, program startup errors, and provide a list of problems found.

With the help of registry repair programs, you can fix the detected errors and, in this way, restore the operating system to working order.


The Windows operating system also has its own utility for this - Regedit.exe


To run Regedit.exe:


Method 5: Password recovery software

Recovering passwords for Windows 10 accounts can be done using special programs for resetting or recovering passwords. Such programs are especially relevant in case of losing the password of the Administrator account (since the passwords of other accounts can be reset using this account).

For this:

  • Download and install a program to reset or recover account passwords.
  • Create a bootable CD / DVD disc or USB drive (if necessary) using such a program.
  • Restart your computer and boot from the boot media you created.
  • Reset or recover passwords from the required account.

Good day, friends! I already wrote an article about how to restore windows 7. Today, another similar article on the topic is about restoring windows 10. The operating system of the latest release has been noticeably improved. But, and new systems still periodically "fly off". Today we will look at the most obvious, simple and affordable recovery options, and see what new and interesting Windows 10 offers us in this regard.

How to restore windows 10 using Doctor Web antivirus for free?

If the antivirus is not loaded from a USB flash drive or disk in the top ten, we watch the video at the end of the article.

Let's start with the most obvious and simple solution. If you notice that the system is slowing down, there are errors, intrusive advertising, you first need to make sure that your computer is “healthy”. Many symptoms are the consequences of the “work” of virus programs. Yes, there is a built-in antivirus in the Windows 10 system, which is supposed to protect. It is quite enough in most cases. But, if the computer is infected, then alas, it is not enough. We have our own segment of the Internet in Russia, and our domestic antiviruses, for example, Doctor Web, track the threats that appear in it much faster and more efficiently. Licensed Dr Web is paid. But the utilities are free, which is good.

Download the free liveDisk utility from the sysadmin's first aid kit on the website of the DrWeb virus treatment product. Today, two varieties of them have been created - one for recording to a USB flash drive, the other for recording to a CD. I always use this utility and not Dr Web Cure It. The latter is part of the "life disk", which has wider functionality; I'm already used to it.

It is rare, but it happens that on some laptops or flash drives the utility does not load after recording. Be prepared for this, just in case, prepare a blank disc for recording.

When you start the utility, here is a window: (I have a USB flash drive)


Disk creation started:

After creating the disk, we reboot the device from the USB flash drive, for this we insert it into the slot, and restart the computer. You need to go into the BIOS, for this we press the Del key:

In the settings, select the boot menu (Boot) and in the boot settings, select our USB flash drive. Press F10 and when you exit, save the settings by pressing the "yes" key:

You can also try to boot from a USB flash drive without going into BIOS. On modern computers and laptops, when loading, by pressing the F9 (or F11 or F12) key, you can call up the boot menu and then by moving the cursor select our flash drive in this way:


Let's see how to roll back Windows 10 to a previous version of the operating system after updating the system to a new build. Microsoft regularly releases new versions of the Windows operating system.

In each new version of the operating system, the settings and operation parameters change to a greater or lesser extent compared to the previous version. After upgrading to a new build of Windows, some users experience problems with their computer.

Problems can be of an objective nature: some applications stop working, problems with drivers, etc. It is also possible that the perception of the new version is subjective: it seems that in the previous version everything was simpler, more convenient, faster, etc. Therefore, there is a need to return to the previous build of Windows that was running on the computer before the system update.

With such circumstances in mind, provided an opportunity to return to the previous version of the operating system.

If the user decides to revert to a previous version of Windows, there are two options for resolving the issue within a limited time frame:

  • Rollback to a previous version of Windows, in case there was an upgrade from Windows 7 or Windows 8.1 to Windows 10.
  • Reverting to a previous version of Windows 10 if the upgrade happened on Windows 10.

At the moment, you can roll back the system to the previous assembly within 10 days (previously, the time period was limited to a month), from the date of the Windows 10 update.

I have already talked about how to return from Windows 10 to Windows 7 or Windows 8.1. In this article, we will discuss how to roll back an updated build of Windows 10 to a previous version of the Windows 10 operating system.

How to go back to a previous version of Windows 10 (1 way)

You can go back to a previous version of Windows 10 directly from the operating system settings.

To start downgrading Windows 10, follow these steps:

  1. Enter the "Settings" of the operating system.
  2. Open the "Update and Security" section, and then "Recovery".
  3. In the "Go back to a previous version of Windows 10" option, click on the "Get Started" button.
  1. In the “Go back to an earlier build” window that opens, you must specify the reason why you are rolling back to the previous version of Windows 10.

  1. After you check the box in one of the items, click on the “Next” button that has become active.
  2. The next window prompts you to check for updates. Maybe they can fix the issue with Windows 10.
  1. Click on the "No thanks" button.

  1. In the What You Need to Know window, review the information about the process to go back to a previous version of Windows 10. Pay attention to the following points:
  • The process of rolling back to a previous version of Windows will take some time.
  • You will lose any changes made to your computer since you upgraded to the current version of Windows.
  • Reverting to a previous version of the operating system will not affect personal files.
  • To avoid losing important data, make a backup in advance.
  1. To start the process of returning to the previous assembly of Windows, click on the "Next" button.

Wait for the return process to complete.

How to roll back a Windows 10 update (method 2)

The second way to return to a previous version of Windows 10 is by using the Windows PE Recovery Environment.

On a running computer, press the Shift key on your keyboard, then right-click on the Start menu. Select "Shut down or log out" => "Restart".

In the Select Action window, click on Troubleshooting.

In the Diagnostics window, select Advanced Options.

In the "Advanced options" window, click on the "Revert to previous version" button.

In the Revert to a Previous Version window, click on the account name.

In the next window, enter your account password. If there is no password, leave the field blank. Click on the "Continue" button.

To start the process of resetting Windows to a previous version, click on the "Revert to previous version" button.

How to Extend Windows Rollback Period to 30 Days

Microsoft has reduced the amount of time a user can go back to a previous version of the Windows 10 operating system. There is a way to extend the time period for going back to the previous version within 30 days, as was the case before.

Prerequisite: the computer must have Windows rollback files to the previous version. Do not delete system update files yourself.

For the first 10 days after updating Windows 10, you need to do the following:

  1. Run command prompt as administrator.
  2. In the command line interpreter window, enter the command, and then press the "Enter" key:
dism /online /Set-OSUninstallWindow /Value:30

The countdown to the end of the period starts from the moment the system is updated to a new version, and not from the moment the command is executed. You can set a period of up to 60 days (number after "Value:"). All this time, the files of the previous version of Windows will be stored on the computer.

If, after executing the command, an “error 1168” appears, then time has already been lost, you will not be able to return to the previous version of Windows.

Article Conclusions

If necessary, in case of problems or for other reasons, the user can roll back Windows 10 in order to return to the previous build of the Windows 10 operating system. You can use this opportunity immediately after updating the system, for a limited time period.
