What to do if the computer is blocked. How to unlock a computer if you forgot the password what to do if the computer is blocked

Friends, hello. Today's article will be useful primarily to corporate users on Windows-based computers working with standard local accounts. Whereas the entry into accounts with the status of the administrator can only be performed by the company's trustees in the form of IT-section employees. Although with a specific family microclimate with the problem described below, you can encounter using home devices. What is the problem? And this is the impossibility of accessing Windows with notification on the lock screen "The user account is locked and cannot be used to log in." What kind of blocking is, and how to deal with it?

So, we can not enter Windows, because on the lock screen you see it.

Such a blocking is the result of a certain number of unsuccessful authorization attempts in a local account, if the computer's administrator is made by the appropriate settings of the local group policy.

Blocking Windows Accounts

The computer administrator in local group policies can set one or another number of input attempts to user accounts. If this number is exceeded, the attempts are blocked for the entrance. This is such a protection against password selection. Even if we do not have an attempt to select a password to someone else's account, but simply her true owner inattentively entered the characters or did not look at the keyboard layout, log in to the system, even when entering the right password. We have to wait the time set by the administrator until the account attempts are reset. And, of course, until the time of blocking is expired.

This protection is established from the selection of passwords in the Local Group Policy Editor, in the Account Distribution Policy.

When installing such a threshold value, other policy settings - the time before resetting the blocking meter and the duration of the blocking itself - will automatically be installed for 30 minutes.

They can be changed if necessary. And, for example, to set a smaller time to reset the counter of unsuccessful password input attempts.

And the time of blocking the account itself, on the contrary, increase.

Such protection is distributed only to local accounting and does not work when you try to select a password or PIN code for connected Microsoft accounts.

Unlock the locked account can be multiple ways:

Log in from the administrator account and remove the lock;

If access to the administrator account is not possible, remove the blocking by booting from the removable device and reforming something in the Windows registry.

How to unlock your Windows Account if you have access to the administrator

If your account is blocked, but there is access to the administrator's account, you need to enter the last and unlock your own. Click the Win + R keys, we enter:

In the window that opens in the Users folder, we are looking for your account and make a double click on it.

In the window of the opened properties, remove the checkbox "Block the account". Apply.

We try to enter your account.

• Note: If you do not have a password to the administrator's account, do not try to log in with the help of the selection. Password selection protection is valid for all local accounts, including administrator. His accounting after a certain number of unsuccessful authorization attempts will also be blocked.

How to unlock your Windows account if there is no access to the administrator

If there is no access to the administrator account, we produce a DVD or flash drive with a process of installing any version of Windows or Live disk with the ability to edit the operating system registry. Upload a computer from a removable device, in our case, this is a Windows 10 Flashlight. Loading from the file previously saved on the disk. We need the kernel to load with the changed registry parameters.

At the first stage of installing Windows, click SHIFT + F10. Run the command line registry:

In the viewing window, we go to the root of the "Computer" devices and go to the Windows section. Here it is indicated as a disk (C: \\), but the system disk may also be under the other letter. Here you need to navigate the volume of the section. On the system section, we reveal the "Windows" folders, hereinafter - "System32", hereinafter - "config". Inside the last we need a SAM file, this is the so-called registry bush, open it.

Open bush needs to be somehow called, the name is not enough. Let's call it 777.

Inside the registry section, HKEY_LOCAL_MACHINE Now we see a new branch of 777. Reveal the path inside it:

777 - SAM - Domains - Account - Users - Names

Find the name of your account in the "Names" folder. For example, we need a user of Vasya. We look at the choice of Vasi is displayed on the registry panel on the right. We have a value of 0x3f8. The same value, but only in another writing format - with extra zeros of the front and a caps - we are looking for now, inside the "Users" folder.

There is a situation when the computer is blocked, and the user cannot pick up the password to the account. This state of affairs is a rarity, but the memory is unpredictable, and the operating system cannot directly prompt to us (with the exception of the custom prompt, if such was created in advance).

Naturally, to log in to the system, you will need to reset or change the password of the account, as it is not possible to remember! To describe, take the average case when the actions do not interfere with other reasons, and the standard installation of Windows favors a successful outcome.

Unlock your computer

Or just "accounting", pretty, useful thing, but forgetting or losing a cherished combination, it is impossible to log in to the system, both outsider and you personally. Well, if no changes are made regarding accounts, then the entry recovery will take some few minutes.

• We reboot the computer, and after the image of the bios () press the "F8" key to call the download menu.
• Move the navigation keys to move on the "Safe Mode" line and click "Enter".
• We are waiting for the operating system download. Select to enter the "Accounting" under the name "Administrator" (standard profile free from the password).
• We close the help window of the safe mode and go to the "Control Panel" through the Start menu or convenient for you.
• Open the "User Accounts" section. Go to your personal profile and click "Change Password".
• In the field, enter a new combination of characters and save by pressing the corresponding button (if you find the input field is empty, the password will be screwed).
• After manipulating with password, reboot. Now it remains to enter a new password (if it was installed) and log in to Windows.

Note! If your profile is the only record, then the actions described above will be powerless. But there is always a different solution, for example, try, this method was considered earlier and will require the presence of a Windows boot disk.

Surely many fans of the Windows operating system familiarize the situation when a banner with a threatening inscription "Attention, your computer is blocked!" On the monitor. And then the text follows the threat of deleting all data from the computer in the near future. That this does not happen, it is proposed to pay a penalty by making funds to the specified mobile number and get the unlock code. I can't even remove the hated banner. With a new inclusion, it is still bangible on the monitor.

What if the computer is blocked? Top up? In no case! After making the specified amount or send SMS to the proposed number, there will be no Mount-User unlocking code, and the computer will remain blocked. So the most ordinary fraudsters act, which launch viral programs on computers and are counting on the fact that there are naive users. This type of Internet fraud has long been long, and the size of the fine is constantly growing. As a rule, locking the operating system occurs when trying to reproduce or download a videos of dubious content.

So, the computer is blocked, and no action is performed. What to do? In this case, you can enter in two ways - contact a specialist or try to unlock the system yourself.

Unlock via Safe Mode

There is a possibility that the banner hit the computer through the browser, which when started it may offer to restore the session. Do this impossible to do this.

Unlocking throughBios.

If the computer is blocked, you can try to unlock it via BIOS. You need to enter this system immediately after turning on the computer by pressing a specific button or from different manufacturers, these are different buttons and key combinations, for example: F1, F2, DEL, and others.

A starting page with the system date and system time will open, where you need to change the date a few days ago, that is, before the banner appeared. Then you need to save the modified dates by pressing F10 and exit the BIOS system. If such a save method did not work, you should go to Exit and select the "Saving Changes" item, select "YES" and press ENTER. After that, the system will start without a banner.

If these methods did not help and the computer is still blocked, you will have to take advantage of the special program for the destruction of viruses. To do this, you will need another computer connected to the Internet. You need to go to the site Dr. Web in order to download from there a program called Dr. Web Livecd. The downloaded image must be recorded on the CD disk using the Nero program and thereby get the boot disk. Then download the locked computer from the disk on which the antivirus program is installed. Now you need to configure Dr. Web and start scanning. There is a high probability that the fraudulent virus will be destroyed, and the computer will turn on in normal mode.

In some cases, none of the above methods helps and have to use the extreme tool - reinstalling Windows.

Instead of pre-school

Quite often, the user faces the problem of hanging and stopping the computer from viruses? In order to unlock a computer from the virus, you must send an SMS message with the text XXX to the O UUU.

Since 2009, such messages are increasingly pursuing Russian Internet users. As a result, many are thinking about how to unlock a computer without SMS and is it real?

How does computer infection take place with such viruses? The computer is infected with an SMS virus through a global Internet network and in most cases due to the users directly. Basically, the infection of the computer occurs under the guise of installing a certain software or opening a picture. For example, on the attacker's site there is a video, which is real, downloading the codecs from this site. After starting the codec and the computer is infected. As a result, hitting the user's computer, the SMS virus blocks it and displays the following types of messages:

Windows operating system is blocked. In order to remove the blocking, you need to send an SMS with the text XXX to the Number of the UU;

Send a message to the Houu with the text XXX, otherwise Windows will be deleted;

To restore the proper functioning of the computer, send a message to the Houu with the text xxx.

In the end, the virus asks to send a message to a short paid number. The cost of such a message may be the most different, usually the size varies from 10 to 200 rubles. However, you should not believe the attacker. In reality, a person will give a much more than a large amount than indicated on the screen. Here are the most common short numbers to which the attacker asks to send a message: 1350, 3649, 4460, 9691, 9800, as well as many others.

Since November 2009, new versions of SMS viruses appear on the Internet almost every day. The most interesting thing is that even those users who have any kind of antiviruses with fresh update databases on their computers cannot be resistant to such viruses: Kaspersky Anti-Virus, Dr.Web, Avast, NOD32 and others. And yet, how to unlock your computer? Only special services for unlocking a computer that are updated every day can help in these situations. Without paying for the fact that SMS viruses are so much common, the epidemic takes a localized character. In other words, in America, China or other European countries, users do not know about such a problem. The main reason is that short SMS numbers can buy any person of our country. Why are short-tone operators doing nothing against extortioners? According to these people, they absolutely do not control the final assemblers of the SMS MZDA. Operators sell such a service as a "short number" through affiliate structures, and no longer respond to anything.

For an SMS virus, it is not easy enough to block the Windows operating system. He still needs to force frightened users to send a message to a certain short number, and in this case there are a wide variety of methods.

The first method is the most "impudent". The user is reported directly that its computer is infected with the virus. For maximum effect, the creator of the virus launches the reverse timer, giving a person to thinking only a certain amount of time, that is, creating some pressure. Unlock a personal computer, while removing the virus, you can send a message somewhere into the air. The method is the most direct.

Most likely, the first way of extortion money is not quite profitable, so the attacker actively apply a creative approach. Another way of extortion is already pressed on the guilt of a computer user. That is, a person does not feel the victim of the situation, and he himself is to blame for his theft. A similar virus can scare the user with the following contents of the message: "Your operating system is blocked, since you use non-license-free software on your computer" or "This computer has a non-license-free version of Windows. The computer is blocked. In order to unlock the computer, you should send SMS to a specific number ". For a larger effect, the message is hanging at the bottom of the screen that the computer is blocked at the initiative of Microsoft.

Of course, an experienced computer user is unlikely to believe that the pirated version of Windows can be unlocked for 150 rubles, at a cost licensed 100 dollars. However, what to do novice users? These people basically choose a more easy way, that is, you pay the SMS message. Sometimes the message states that you can unlock the computer through the terminal.

So how to unlock a computer without payment? To date, remove the SMS virus can be very fast. For example, you can completely rewrite the text of the enemy message with the number to which it should be sent. The next step is necessary with the help of a friend of a friend to enter the Internet, namely, the special service of Kaspersky and get the unlock code from them. By the way, unlocking is absolutely free. How else to unlock a computer from the banner? You can ask a friend in the telephone mode to go to Kaspersky Service and send you the code that you enter directly on your computer. This method will take no more than five minutes.

What are free services to unlock computers from viruses? The most common service is Kaspersky Anti-Virus. You need to enter the next page: http://support.kaspersky.ru/viruses/deblocker. Then, enter the phone number, which is specified in the enemy message and directly the message text itself. Then you need to click "Get an unlock code" and get the code itself.

In case the Kaspersky service has been confused by the Kaspersky service, you can always use the services of a free service Dr.Web. Here you need to go to a certain wanderer of the site: http://www.drweb.com/unlocker/index and to determine what kind of unlocking mechanism to use. Total Dr.Web offers three different computer unlocking methods.

It should be remembered that with whatever speed viruses, the main protection against them is the installation of antivirus. If there is no antivirus on the computer, there is always a threat of infection. Now it is not necessary to buy an antivirus, there is a lot of free antiviruses that can be downloaded absolutely free.

Now blocking banners have a huge number, some of which the virus computer is blocked to replenish the MTS account. Plus, new types of computer lock appear daily, damage from them is estimated by millions. Most modifications have become more complex in deactivation and do not contain the correct PC unlock code in themselves.

The computer is blocked by a virus what to do? Unfortunately, no one, from us 100% is not immune from it. Such curious often happens not only with you, it can happen with each. The situation is not pleasant when the window appears your computer is blocked for viewing, or copying video footage of pedophilia and violence. And in case of no payment of fine 1000, 2000 rubles, or even more - all the data will be removed.

Virus Blue Screen The computer is blocked for watching porn is not displayed on the back, not removed by antivirus, and the load does not give the result in safe mode. Because of blocked the computer, ask to send SMSMany programs are not launched - nothing can be done except to enter the code to pay a fine, but for this you need to send an SMS or replenish the bill Beeline, MTS.

For maximum convenience, hackers to get a computer unlocking code on the screensaver in more detail paint a fine scheme. The amount of the fine is sometimes the most different, SMS messages for unlocking significantly rose up to 3000 rubles. One time it was cash translation through WebMoney or Yandex Money. Where, by filling out the current account, specified on the screen you needed to reach the nearest terminal and from your card to transfer money to scammers, and now the scammers have a softer scheme - this mobile phone numbersin. However, even after such an operation, there is no guarantee that the numbered computer will be unlocked. As a result, nothing remains with an upset user, except to contact the computer service and call a computer master to the house.

If a blocked computer is unlocked thanks to an SMS payment, then you are very lucky, as a rule, it does not lead to a proper effect. Do not translate money to virusers to the services: the services they offer are 99% fraudulent.

When you chose a day, you also need to choose a control point of the recovery in the list, so click [System Control Point]. Click [Next\u003e]. Confirm the selection of the control point, clicking [Next\u003e]. It turns out that the computer loads the OS in that configuration when it was a few days ago before the banner got on it and blocked the computer.

Therefore, when you turn on the PC after the update, if you offer your favorite browser to update the session, then in no case restore the scape. There are viruses, followed by unlocking sites on the computer.

1 way - editing registry

Do not be afraid)), it is very simple and will not take much time. Do not want to do this, call us and we will do everything for you. Let's do everything in order. To gain access to the registry, you need to download a blocked computer in with command line support, for this, when you turn on the computer, press the F8 key and in the download menu select a secure command line support mode.

1. HKEY_CURRENT_USER / SOFTWARE / Microsoft / Windows / Currentversion / Run

here we see a list of autoload programs (run along with the operating system), as well as their location on your PC (which if then delete them from the disk). All suspicious programs need to be removed (right-click and delete) and remember the path to them (for example: GRG54545.exe, bh.exe along the path C: / Documents and Settings /; C: / Windows / System, etc.)
2.HKey_Local_machine / Software / Microsoft / Windows / Currentversion / Run - We repeat the above.
3. HKEY_CURRENT_USER / Software / Microsoft / Windows NT / CURRENTVERSION / WINLOGON-

Here should not be the parameters of Shell and Userinit. When they are detected, feel free to remove.
4. HKEY_LOCAL_MACHINE / Software / Microsoft / WindowsNT / CURRENTVERSION / WINLOGON - on the contrary, should be present and conform to these values \u200b\u200bof Userinit - C: Windows / System32 /Userinit.exe
