Reset Windows 7 password using a USB flash drive. “Global login problems” or “How to remove a password from a computer

1. The protection is now installed only to enter the BIOS, and you need to make sure that the password is requested every time you start the computer. To do this, you need to find the item in the menu « Password Check » → set its value to “Always”;
2. Save your password by selecting « Save and Exit Setup » (can be located either in the general tab or in « Exit » ).

This guide will tell you what to do if you forgot your Windows XP password and how to solve this problem without reinstalling the operating system. In addition, we will consider other possible problems with passwords. Operating Windows systems 10 and Windows 7 have improved security features over older early systems Windows XP/2000.

By the way, perhaps one of the frequently used passwords is set on your PC, full list popular passwords look - .

The latest versions of Windows use a more effective password system designed for business use to ensure that no one without the necessary permissions can access information on your computer. This is a double-edged sword. Most users forget some important password at least once. And then the user/owner of the information becomes the “enemy without access rights” for his computer.

Naturally, for every method of protection there is a way to bypass it, especially if you have physical access to the computer.

In this article we will look at various methods protecting your computer with a password and ways to bypass them. We won't start with user account passwords, but with equally important passwords, such as BIOS passwords.

How to "bypass" the BIOS password?

BIOS password- one of the oldest methods of protecting a computer from unauthorized access and one of the most common. Why? This is one of the most effective means if the user does not have access to system unit. Otherwise, it is the same as locking your house with many locks and leaving the window open.

The default BIOS settings on all motherboards do not store password information. So everything you need to do to clean up BIOS password, - simply reset the current settings, restoring the default configuration. But remember that resetting the current BIOS settings will destroy not only the password, but also all the settings that you set yourself.

There are two ways to reset BIOS settings. Most motherboards have a special jumper for clearing CMOS (the memory in which BIOS settings are stored). Usually this jumper is located near the battery on system board, but to be completely sure, it is advisable to refer to the instructions from the motherboard. On some motherboards instead of a jumper there are simply two contacts that reset CMOS you need to close it with a metal object, for example, a screwdriver.

If your board has a jumper, then to clear CMOS, turn off the computer, install the jumper so that it closes the jumper contacts, and press the computer power button. Your computer will not boot, but your CMOS settings will be reset. Remove the jumper and turn on the computer again. You will most likely see a screen asking you to press F1 to install BIOS settings. If you are happy with the default settings, press F1 and BIOS menu select ‘Save and exit’. After this, the computer will boot as usual, except for the BIOS password.

If you don't know where the required jumper is located on your board or if it doesn't exist at all, which is quite possible, you'll have to go a different route. Each motherboard has a battery that powers the CMOS memory, allowing it to store information. As a rule, this is a standard CR2032 battery.

To clear CMOS, turn off the computer and remove the battery (you may need a thin screwdriver). After 5-10 minutes, replace the battery and turn on the computer. The BIOS will be set to default settings and there will be no password. To continue booting, you will need to press the F1 key, and if you are satisfied with the default settings, select the ‘Save and exit’ item in the BIOS menu that appears.

As you can see, all this is very simple desktop computer, but with a laptop, the BIOS password can become a serious problem. Due to the frequent theft of laptop computers, manufacturers have made it almost impossible to gain access without passing the password. So, if you have forgotten your laptop's BIOS password, you will most likely have to contact service center manufacturer.

What to do if you forgot your Windows password?

If circumstances have developed in such a way that you have forgotten your Windows password, then we recommend that you reset it using the built-in account called Administrator. This is done in safe mode, while booting or rebooting your PC.

To restore access to your computer, you will just need to press F8 and in the menu that has already opened, in which you will be presented with some additional options boot your operating system, you will have to select the above " Safe Mode" Next, you will need to select a built-in account, which, by the way, by default, cannot be protected by any password.

If you did everything correctly, since you strictly followed the above sequence of actions, then while still on the Desktop, you should see a window with a message that Windows is running in the “Safe Mode” you need, which is as simplified as possible. You will need to click “Yes” and go to Control Panel - User Accounts, where there is an icon for the account for which you want to reset the password. On the left, you must select “Change Password” and in the appropriate window enter and then confirm a new password. Ultimately, you will need to restart your PC for the above changes to take effect.

How to crack Windows password on a computer or laptop?

In order to do this, you will have to follow the following sequence of actions:

1. Prepare a CD or flash drive on which a special set of resuscitation programs intended for Windows recovery. You will need to insert it into the drive or into the appropriate port during the subsequent reboot of the computer. You can prepare this package of resuscitation programs yourself by downloading programs intended for separating, saving and restoring data, or you can download some ready-made RBCD 10.0, for example;
2. When starting the PC, in order to enter the BIOS, press the “DELETE” button. There we will need to change the installation priority and assign the computer to boot from the CD-ROM. After that we visit our boot disk into the disk drive and reboot the PC;
3. Having entered the resuscitation disk, which should appear after the resuscitation program package has been loaded, we must select the editable copy of Windows and go to the “System Restore” mode - the section that will be located at the very bottom of the page;
4. We look for the command line and enter “regedit” there (we look for it in the dialog settings of the same window). We find and then select the HKEY_LOCAL_MACHINE section, in which we need to select File, and then Load hive;
5. Open the “SAM” file and select the section - HKEY_LOCAL_MACHINE\hive_name\SAM\Domains\Account\Users\000001F4. Double-click on the F key located there and go to the very first value located in the line, which we will need to replace with the number 10;
6. In the same section, select “File”, and then “Load Hive”. Click “Yes” to confirm unloading the bush. We close the registry editor, thus completing the installation process, take out the flash drive or disk and reboot the computer.

How to find out your computer password?

The question: how to crack a password on a computer still remains relevant. Unfortunately, to really find out the password from a computer is only possible by choosing it correctly manually. Therefore, if you are not ready to spend several hours of your free time on this process, we strongly recommend that you simply reset it and come up with some new one.

Again, it’s much easier to just reset the password and come up with a new one afterwards. However, if you specifically need to find out the password, we recommend that for these purposes you use a program called, from the image of which you will need to make a boot disk. Setting it up correctly loading BIOS from the drive and installing this program, immediately upon entering the Desktop, a window will open in which you can see user names, including the Administrator, as well as passwords for their accounts.

When wondering: what to do if you forgot the password from your own PC, it is not at all necessary to use the above methods for restoring it. You can also reset your password in the Windows 7 operating system using the Net User command. To do this, while rebooting the PC you will need to press F8. Thus, you can open a Menu that allows you to make additional options for loading this operating system, in which you will need to select not just “Safe Mode,” but one that also supports the command line. While in it, you will need to select the built-in Administrator account and in the Command Interpreter window, immediately after this, system prompts will appear where you will need to enter net user “username” “password”.

We assume that you yourself understand that instead of “username” you will need to enter the name of your local user account, and instead of “password” you will need to enter a new password. If you did everything correctly, then in order to close the window, you will need to enter exit on the command line and restart the PC.

How to reset your password on Windows 8?

In the case of this operating system, things are much simpler! You can reset your password on Windows 8 as follows:

3. In the window that opens, you will be required to enter and then confirm a new password. Next, in the command boot window you will need to enter Exit and restart the PC as usual.

View the passwords that Windows stores

In addition to access passwords for various Windows users stores a number of other, equally important ones: Internet connection password, passwords mailboxes or access to websites. As a rule, there are quite a lot of them, so it is quite natural that they are forgotten over time.

The operating system offers an "autofill" feature for passwords and other frequently entered information in browsers ( Google Chrome, Yandex.Browser, Opera (Blink), Firefox, Explorer 11, etc.). So it is not uncommon for a user to enter a password once, and after a few months, naturally, cannot remember it. Everyone understands that important passwords need to be written down, but not everyone does this. And if you no longer remember the password, how can you find it out, since it is displayed as a series of asterisks: ******?

Programs offer a solution different manufacturers, which can get the password from this string of asterisks. There are quite a lot of freely available programs for decrypting Windows passwords or hidden passwords from input lines in various browsers.

We will use a program from Passware. This is an easy-to-use, freely distributed program that analyzes passwords hidden by asterisks and reports them to you. She is very easy to work with. Just highlight the password line and click the ‘recover’ button.

Of course, there are also commercial versions of programs, which, as a rule, have a greater range of functions. For example, Password program Recovery Toolbox scans the system and identifies saved passwords, data saved for automatic filling, Outlook Express passwords, Internet connection passwords, etc. This information is then presented in a convenient form. A few more alternatives to the programs described above: , or Password Viewer.

Windows XP user passwords

Windows XP stores user passwords in a modified form. For example, the password "password" would be stored as a string like this: 'HT5E-23AE-8F98-NAQ9-83D4-9R89-MU4K'. This information is stored in a file called SAM in the C:\windows\system32\config folder.

This part of the SAM file is encrypted system utility syskey to improve password security. The data necessary to decrypt the information after syskey is stored in system file in the same folder. But this folder is not available to any user. Only the operating system itself has access to it during its operation. You can access the SAM and system files only when running a different operating system or by connecting the drive to another Windows computer.

All Windows versions XP have an "administrator" account. This name gives the user full access to the system and the ability to reset passwords for all other users. This can save you if for some reason you cannot log in with your regular user password. The specifics of using the administrator password depend on the version of Windows XP: XP Professional.

The administrator password is set during installation of the operating system. If you wrote it down or just pressed enter and left it blank, you can easily log in as an administrator and reset user passwords. To log in to the system in administrator mode, on the system welcome screen, press CTRL+ALT+DEL twice, a window for entering the administrator password will appear.

When the computer boots, go to ‘start\control panel\user accounts’ (start\control panel\user accounts) and change the required password. Since you are already here, this good opportunity fix your mistake if you left the administrator password blank. In addition, it is advisable to change the name of the ‘administrator’ account. This name is known to everyone and is the first name used to gain access to your computer. To change the account name, right-click on 'my computer' and select 'manage'. Expand ‘local users and groups’ ( local users and groups) and open the ‘users’ folder. Right-click on the 'administrator' entry and edit it.
XP Home.

This system will not allow you to simply access your computer in administrator mode. First, you will need to boot your computer into crash protection mode. To do this: restart your computer; immediately after testing the BIOS, press F8 several times; in the menu that appears, select ‘start Windows XP in safe mode’ (boot Windows XP in crash protection mode). When the computer boots, log in with the username ‘administrator’. There is no default password. You can now change user passwords by going to 'start\control panel\user accounts'. When you're done, restart your computer as usual.
Creating a password reset disk

Windows XP allows you to write information onto a regular floppy disk that provides the ability to reset your password. Naturally, if you have already forgotten the password and cannot access the system, then you will not be able to create any disk, but it is worth creating such a floppy disk in advance to protect yourself from such accidents.

To create a floppy disk: go to ‘start\control panel\user accounts’ (start\control panel\user accounts); select the name under which you are logged in; in the related tasks menu, select ‘prevent a forgotten password’; follow the instructions of the wizard that starts.

To reset passwords using a floppy disk: if you enter the login password incorrectly, the system will ask whether you have forgotten it; at this point you will be able to use your floppy disk by following step by step instructions operating system.

Be careful: if you used built-in Windows features to encrypt files and folders, but did not install the operating system update (service pack 1), removing the password will result in the loss of encrypted information.

Utilities for changing passwords Windows XP/7/8/10

There are special utilities that allow you to edit or reset Windows XP/7/8/10 user passwords. The way most of them work is to boot a minimal version of an alternative operating system, such as DOS or Linux, under which you can access password files.

An example of such a utility can be found at this address: http://home.eunet.no/~pnordahl/ntpasswd/ Instructions for operation, as well as files for creating a bootable Linux disk, are available on the same website.

Please note that if you have used the operating system's functions to encrypt files and folders, by changing the password using any program, you will lose access to the encrypted data. In this case, the following method may help, allowing you to avoid replacing forgotten password new, but recognize the old.

Selection and decryption of passwords

If nothing else helps, but you have physical access to the computer, then all is not lost. You can rewrite the config and SAM files and try to decrypt the passwords stored in them using special utilities third party manufacturers. As we already said, for this you will have to use an alternative operating system, such as DOS or Linux. And when the files are at your disposal, you can use one of the programs for decrypting passwords, for example, LC4 or.

You will need:

1. Access to another computer.
2. At least two empty floppy disks.
3. An archiver designed to work with the command line, for example, RAR.
4. DOS or Windows 98 boot disk (image required disk can be obtained from http://www.bootdisk.com/) or the minimum Linux version(eg Knoppix). There is no need for boot disks if you can simply connect your hard drive. If you are using a DOS boot disk and the partitions on your hard drive are using file NTFS system, then to access them you will need a program that allows you to view partitions in NTFS format under DOS control, for example, NTFSDOS.
5. Program for obtaining passwords. We recommend using since the beta version of this program is free and free version LC4 is very limited.

Using a bootable USB flash drive:

1. If your hard drive has NTFS partitions, copy the NTFSDOS file to your bootable USB flash drive.
2. Copy the archiver (RAR) to the bootable USB flash drive.
3. Boot your computer from this flash drive. If there are partitions with NTFS, type the NTFSDOS command, this program will show which letter is assigned to your system disk, it will need to be used instead of the letter C in the next paragraph.
4. Archive system files with passwords. For example, if you are using the rar32 archiver, the corresponding command will look like this: Rar32 a -v a:\systemandsam c:\windows\system32\config\system c:\windows\system32\config\sam If the files do not fit on one flash drive, the archiver will ask you to insert a second one.

Hacking passwords

Each program you select will display a list of accounts detected in the SAM file. Select those for which you need to define passwords. If you are using , select Attack type: Brute-force. If you used only numbers in your password, check the ‘all digits (0-9)’ box. Start the password recovery process using the command from the Recovery menu.

Password guessing can last from 10 minutes to several hours, or even several days, and may fail. Especially if the password uses letters in different cases, numbers and special characters.

This is a good way to check the strength of your passwords. If you just want to check your password, follow the steps above and see how long it takes to guess it.

Windows password cracking programs

There are a huge number of software tools that can help you crack your Windows password. Apart from the above-mentioned program, there is also Windows Admin Password Hack. But, unfortunately, it can no longer be called current, since it only works in Windows 2000/XP. Its closest replacement is MultiBoot 2k10, which is essentially a feature-rich boot disk.

Conclusions

In any case, if one of your loved ones forgot the password for Windows 7, or you yourself were forced to face this, do not despair, there are plenty of solutions to this problem. Well, so that you no longer have questions: how to crack a password on a laptop, we strongly recommend that you save them somewhere, in notes inside your own smartphone, for example.

Although this has its downsides. It turns out that anyone can log into the account. Protect your personal information in several ways - not just with the code in your account.

Our forgetfulness often plays various unpleasant jokes on us. Forgetting a password for a program or for Windows is a completely common thing and happens to literally every second user. Especially with those of them who write down passwords not in a notebook, but on pieces of paper scattered everywhere, or even rely on their powerful and bottomless memory. And who is not familiar with the situation when the password for an account is forgotten? network resource- on some Facebook or Vkontakte.

Imagine that in this situation, valuable data or simply the carefully organized software environment of the Windows operating system is at risk. Who wants to reinstall Windows and reinstall all the programs? There are no such individuals in nature. The decision, in in this case, performs . We will talk specifically about Windows 7, since approximately the same password reset procedures are valid for the G8. And this, whatever you say, is the most widespread operating systems installed on the computers of hundreds of millions of users.

To begin with, we will discuss the most simple procedure reset using boot Windows image on a CD (like the common “LiveCD”) or a bootable flash drive, similar in functionality. We also need a minimal understanding of the command line. Using these means we will try to remove existing password on behalf of the administrator. In conclusion, we will offer for consideration some other options for user action in the event of a forgotten password.

At the preparation stage

Preparing to reset your password in Windows 7 will involve one tricky procedure: we will change system program Sticky keys on the command processor.

The command processor - the cmd.exe file - is precisely the system utility that is responsible for providing the command line interface. To launch the console, you need to run this file. Replacing the sticky utility with a command one Windows console 7, we will be able to manage the process of entering and changing the password.

Please note that we will need a proprietary installer for the “Seven”, which includes administrator functions, such as “System Restore”. Some stripped-down versions of installation disks and flash drives do not contain administrator functionality. So, let's begin our preparatory steps for the reset:

copy c:\windows\system32\sethc.exe c:\

• Thus, we copy the keystroke handler to the root of the “C:” drive, that is, we create a backup copy of the handler, which we need to remove and replace with the cmd.exe file. We do the replacement according to the command:

copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe

That's all the system administrator's preparations for resetting the password on Windows 7. The reset itself will be described in the next section.

We are struggling with authentication in the system

To remove authentication from the system, proceed as follows:

• Remove from the system bootable media and log in through the normal Windows boot procedure.
• When logging in, we will be asked to enter the password of the administrator or other registered user of the system.
• Instead, press the Shift key five times. This will launch the command processor, which will allow us to remove the forgotten password. In order to reset it and remove all information about previous authentication, type the following command:

net user Username New password

As you can see, it also allows you to remove the old username and assign a new one to it.

• Everything is ready, you can log in with new credentials.

This seems to be the easiest way to reset your credentials using the console. All that remains is to “plant” the file sethc.exe that we moved in its place. Copy it back to the C:\Windows\System32 folder. There are alternatives to this procedure, which can be found here: http://www.3dnews.ru/623507.
