Every computer, be it desktop computer, laptop, netbook or tablet during installation operating system windows is given a name. All computers have it individually. Know him to a simple user not at all necessary, but if your computer is connected to local network, then you can create on one (or all) of the computers shared folder to exchange information, and for this you need the name of yours and all computers on the network.
There are many ways to find out the computer name, but I will tell you only about five. This, I think, is quite enough. All these methods can be applied on any Windows operating system/
Determining the computer name using the Run window
Open the window " Execute" To do this, press hot keys on the keyboard Win + R.
A window will open in which you need to enter the command msinfo32 (without space)
And click the button below OK».
The window “ System Information", in which you need to find " System name" in a collumn " Element».
This is the computer name.
Determining the computer name through “My Computer”
Click right click mouse on the " My computer" (in Windows XP), or " Computer" (in Windows 7), or " This computer" (in Windows 10), and select the item " Properties».
If there is no such icon on your desktop, then find the link of the same name in the menu “ Start", right-click on it and select " Properties».
The System window will open. On the right, find the block " Computer name, domain name, and workgroup settings", and in it the line " Computer" And " Full name ».
This is the name of your computer.
Find out the computer name by the shortcut
Select any shortcut on the desktop. This should be a shortcut, not a folder or a file.
The label has a small blue arrow at the bottom right.
Right-click on the shortcut and select “ Properties" It is usually at the very bottom.
The window “ Properties: Shortcut name" Go to the " Details" In line " Owner" And " Computer p" you will see the name of your computer.

In order to quickly get to command line Let's use the window again " Execute" To do this, press the treasured keys on the keyboard Win + R and enter the command cmd, and press ENTER(on the keyboard) or the " OK».
In the command line window, enter the command hostname and press the button on the keyboard ENTER.
Below you will see your computer name.
First, we should talk about how to find out the username of a computer. To do this, just click on the “Start” button (or a button in the form of a checkbox on your keyboard) and look in the right top corner menu that opens: usually the user name is displayed in the upper right corner, next to a small picture.
You can also find out the username when the system boots. If there are multiple users registered on the same computer, their names will be visible in the user selection menu, which usually does not appear. The same menu will appear if a password is required to log in, even if there is only one user.
You can change your username through account management. You can access it through “Start”, then “Control Panel”. The path to the option we need in different versions operating system is slightly different, but the name always includes “User Accounts”. Finding your name account, here you can rename it.
There are two ways to view the computer name. The easiest one is to right-click on any desktop icon and select “Properties” from the menu that opens. In the “Details” tab, among other information, you can see the computer name (usually the last line). You can't change the computer name from here, nor can you change most of the other properties displayed.
Another way: open the “Start” menu, find the “Computer” item and right-click on it. A menu will open in which you need to select “Properties” - the “System Properties” window will open. Opposite the lines “Computer:” and “Full name:” you can see the computer name. Here you can also find the name of the workgroup to which the computer is included, and a number of other useful information.
This window can also be opened through the Control Panel, which can be accessed through the Start menu, but the path to it differs in different versions of the operating system and when different settings interface. In Windows XP, in category mode: Control Panel → Performance and Maintenance → System, and in classic mode you can immediately select “System”. In Windows 7 and 8, the path is different: Control Panel→ System and Security→ System.
The actual full computer name consists of the user name and the character set that the system adds to it. For example, the Windows 7 operating system adds "-PC" to the username. If the username was "User", then the computer name will become "User-PC". Other versions of Windows may modify the computer name a little differently, but in approximately the same way - adding something to the username. Thus, you can not only find out what the name of my computer is, but also understand how this name is formed in its final version.
When the system prompts you to enter a password (if one is set), . To know login You can also do this by performing a few simple operations. To do this, go to the Start menu and select the Control Panel section.
Next, select the “User Accounts” section. Once you enter this menu, you will see all the accounts that exist on your computer. As a rule, there is one on a personal PC. Therefore login also one. It is assigned by the operating system. If desired login you can change it, put another one, create a new account. It is also worth canceling that on computer There may be several accounts, but you can only be in one at a time. All data is stored in the “User Accounts” section.
There is another way that allows the account or user name. Go to the Start menu and select Shut Down. Click on the triangle next to the item. The system will offer you several options for action. Select the "Change Account" tab. The window that opens will display all the accounts that have been created on your computer. If there is only one account, then login there will be one.
In Windows 7, you need to click on the triangle next to the “Restart” command. In the window that opens, in the top line, select the “Change user” command. This is how you can easily find out under what name your personal computer is listed and how many accounts have been created.
Administrators and employees service center When accepting a computer for repair, they often ask the same question - whether the user has saved his personal data. But how to do this if you are new to using a computer and don’t know where to look for them? Exist certain places, in which the operating system stores user data by default.
You will need
- - administrator rights.
Instructions
Open My Computer or any file manager you like. Go to drive “C:”. Search on it Users folder or “Users” if your operating system is Russified. Go to this folder. Find the folder that matches your name or your account name. All files located in it relate to your work on computer- data installed programs, documents, photographs, music and cinema.
You can find your drawings in the “Images” folder, your documents in the “My Documents” folder, -files in the “My Videos” folder, and so on. Save files are stored in the "Save Games" folder - copy them if you plan to continue playing this game from the same place.

Login and is always unique and safe. They are needed to maintain the secrecy of correspondence, the confidentiality of information and to protect yourself from scammers.
Instructions
It seems that from the billions of logins on the network you can already choose your own, unique one. Any postal service will definitely offer you a combination of last name, first name and date of birth, or some faceless option. You can use the one proposed as a basis, but supplement it with something else. For example, a husband (wife), the name of a favorite pet, or a book character, etc.
It is best to add numbers, but in no case should they coincide with the numbers of, say, the future login. Digital combination should be easy to remember, which will make it easy to recover the password later. For example: marina_oleg_2011, or oleg2011marina.
The situation is more complicated. As practice shows, it is precisely because of its simplicity or logical calculation that users lose their mailboxes, valuable information, are unpleasantly surprised by spam from their own email or even worse - the loss of important financial or personal information. And the consequences will not force themselves.
Therefore, the password should be as complex as possible, consisting of at least 12 characters and including both letters, uppercase and uppercase, and numbers. Combinations that include name, birthday, passport number, home address, etc. should not be used. The more “confused” it is, the . Even if it is a random set of numbers, it will be an additional guarantee against hacking.
You should not save your password in your mailbox, much less save it on your computer.
Don't be lazy to keep yourself a little notebook
book, and duplicate the entries somewhere else, for example, in your phone. Remember, a lost password is the key to problems.
Don't try to remember complex password straightaway. As used mailbox it will become “normal” for your fingers.
Important! Never give your username and password to anyone, under any pretext! Even if you receive letters from the resource administrator or calls from people unknown to you, no matter what the reasons are: an attempt at hacking, configuration, a system failure, etc.
All of the above applies equally to mailbox logins and passwords, as well as game logins and passwords, electronic payment systems, work on the stock and foreign exchange markets, etc.
So, be unique, but don't forget about safety.
Every computer has a name. Every time you install windows or create a new user account, you can name the PC or account. This point is especially important when organizing a network, be it at an enterprise or at home. In this case, it will be much more convenient if each machine has a name that is easy to recognize. It is also possible that, due to someone’s negligence, several servers on the network are named the same, which causes conflicts in operation.
In this article we will show you how to edit your account
The system automatically assigns itself a name, but very often it consists of a set of numbers and letters, so figuring it out can be very difficult if there are several of them. This drawback can be removed very simply. In addition, sometimes you may need to rename the user without reinstalling the Windows OS and many additional manipulations. In this article we will show you how to change the computer name and user name, and also learn how to change them.
How to find out and change the computer name
To find out the name of your PC, use one of the methods.
Method 1
Press the combination Win keys+ R, after which we type msinfo32 in the window that opens. A window will open with complete information about your system. In the “System name” line you can find out the name of the PC.
The help shows the computer name
Method 2
In older versions of Windows, for example 7 or 8, you can right-click on the “My Computer” icon and select “Properties”, closer to the bottom of the screen you can see the name of the PC. In Windows 10, this information can be viewed by launching Explorer so that all drives are displayed, and clicking the “System Properties” button at the top of the screen.
Method 3
If you store application shortcuts on the desktop, right-click on any of them, select “Properties” and switch to the “Details” tab. The name of the system is contained in the very bottom line called “Computer”.
Launch the command line by pressing the Win + R combination and typing cmd, then type the hostname command in the command line. On the next line you will see information about the name of your machine.
Method 5
Use one of the programs to obtain information about your PC, for example, AIDA64 and the like. You just need to launch the “About Computer” tab or some other similar name, and you can see all detailed information, including the title.
The principle by which the name of a PC is changed is the same in all versions of Windows, even though the interface may differ. If you are using the latest Windows 10 OS, you can click the Start button - Settings, or you can directly go to Settings by clicking windows combination+ I, then go to the System tab - In the system. The most top line called “Computer Name”, and below it you will see a “Rename Computer” button. Click it, enter a new name, after which you will be prompted to reboot. Agree, after turning it on, your PC will have a new name.
Click Change Settings to rename your computer
In the same Windows 10 or in older versions, you can rename the laptop using standard interface. To do this, you need to right-click on the Start button and select System or Control Panel - System, and in the older windows versions you need to click Start - Control Panel - System, where you will see all necessary information about your car. In the left column, click on the button " Extra options system", then go to the "Computer name" tab and click "Change". Enter a new name, click OK - Apply - OK and restart your PC.
The third method is universal for all versions of the system, using the command line. Run it as administrator and type the command:
wmic computersystem where name="%computername%" call rename, name="New_computer_name"
where instead of "New computer name" you need to type the new name you want to use. We warn you that there should not be any Russian characters! After the utility displays a message stating that the procedure was completed successfully, reboot the system.
How to find out and change your username
The username is a slightly different function. If the computer name is the name that is assigned to the machine to identify it on the network, then the user name is the name of the profile with separate settings, of which there can be several and thanks to which several people can use one machine independently of each other and without interfering with each other. There are two types of accounts:
- Local account - exists only on this PC and allows you to use most of its functions.
- Network account - linked to services Microsoft and to connect it you need to log in to remote server. The main advantage is the availability of absolutely all services that exist for the Windows OS, while the disadvantages are worth noting possible failure connections when there is no Internet.
If we consider the accounts and compare them according to the management capabilities provided and access to functions, we can distinguish the following types of users:
- Administrator - users who have full access to absolutely all functions and settings of the laptop and can change them at their own discretion. If there is only one user, he automatically becomes an administrator.
- User - gain access to almost all functions, but their rights are limited; they can't change system settings and functions. There can be several users, their settings are not intertwined.
- Guest is the most limited profile. Designed for one-time viewing of content without the ability to change anything. Most often it is set up for children or friends who may temporarily need your PC.
Now let's learn more about how you can change your account data and change your user name. It should be noted that the PC must have at least one account with administrator rights, otherwise it will simply be unmanageable. It is the administrator who can perform all manipulations with accounts. In addition, you must remember that if there is only one profile on the computer, it will always have administrator rights and it will be impossible to change its type. Also keep in mind that rename the user in the specified way Only a local account can do this. Network profile you will have to change it via the Internet using a browser.
Renaming a local account
To rename a local account, use one of two methods.
Method 1. Through the account management menu
Go to Start - Control Panel - User Accounts (or right-click on the Start button, select Control Panel - User Accounts) and find your profile. Click "Change your account name", add your nickname and click "Rename". You can change other accounts in the same way if you are an administrator.
Method 2. Through the command line
Launch the command prompt as an administrator by right-clicking on the Start button or the “My Computer” icon and selecting the appropriate item. Enter the command:
wmic useraccount where name=”Old Name” rename “New Name”
and wait until the procedure is completed. You won't even need to restart your laptop.
Renaming an online account

Finding out Windows 7 usernames / Sandbox / Habrahabr
There is a bug in Windows 7 that allows you to remotely find out usernames on a peer-to-peer (home) network. About corporate networks There is no discussion here, although it does exist. Beginning players often want to make fun of their neighbors in the hallway or even in their house, find out their secrets and then perhaps even manipulate them for their own purposes. Typically, the provider connects the entrance or house into a home network. Users can share files (shared resources) in it, arrange network games, communicate without access to the Internet. Currently, the practice of connecting subscribers directly to the Internet is becoming increasingly common, that is, when the computer is turned on, the user will already be connected to the Internet. With this type of connection, the home network disappears, thereby increasing the security of subscribers; it is also worth noting that interest in home network has dropped noticeably and for most, turning it off is not considered critical, the main thing is the Internet. The speed and quality of the Internet also increases. But since not everyone has a direct connection, this topic remains relevant. IN network environment direct connection looks like a local network connection, it does not require additional actions user to connect to the Internet, just turn on the computer and insert it into it network cable. By using additional connection implies the need for the user to connect to the Internet using an additionally configured network connection: The vulnerability that we will talk about is that, remotely, we can find out user names. And then carry out a brute force attack (password guessing), thereby gaining control over the system. You can also find out passwords on a local network by intercepting password hashes using an ARP-poisoning attack. One has only to add that this vulnerability has been known for a long time, but has not been completely fixed. It consists of obtaining the user's SID and further enumerating the RID values. At one time, it was possible to obtain user identifiers by creating a so-called anonymous connection (authorization with empty name and password), but Microsoft fixed this vulnerability by adding an option to prevent SID broadcast to anonymous users in local policies safety But it is still possible to obtain identifiers during guest or user authorization. I'll demonstrate how to do this using Cain & Abel. For a successful attack, the PC must be allowed guest access and the guest account must be activated (this can be determined by the presence of at least one shared folder) or classic access must be enabled and the name and password of one of the users is known. On the “Network” tab we find the PCs of interest.
We connect, go to the “Users” tab, in the first request we will be denied access (available with administrator rights), in the second (it is done automatically) the program will launch SID Scanner, scan the range of RID values (by default from 500 to 2000), relay received identifiers into usernames.
In this program, names in Latin are displayed incorrectly.
This method allows you to find out user names exclusively in Windows 7 of all editions; it could not be reproduced with Vista and XP; it was not tested with server versions. But there remains a possibility that this method It will also work with windows 2008, 2008 R2, as well as windows 8, due to a similar sharing system.
It is worth mentioning that there are many programs that perform similar functions.

To obtain information about the network state it is used ping command. It determines the health of the network and the time spent transmitting packets along the client-server and server-client routes. When using the –a option, new versions of the command are specified by the name computer by IP.
From the Start menu, select Run and type cmd into the search bar. In the command window, type ping –a 10.0.0.20, where 10.0.0.20 is the conditional IP remote computer on the local network. The system will display information about the node, including its name.
If your version of ping does not support this feature, use nbtstat with the -a option. This command returns the NetBIOS name table of the remote host. Prerequisite- Computer support for NetBIOS protocol. Call the command line with using cmd and enter nbtstat –a 10.0.0.20.
The computer name on the local network can be determined using NSLookup commands, if the TCP/IP protocol is installed on it, and at least one DNS server is specified in the protocol parameters. The team diagnoses DNS operation and displays information about it.
At the command line, type NSLookup 10.0.0.20. The command returns the name and IP of the server on this network, and the name and IP of the remote computer. A reverse search is possible: if you enter a computer name, the command will display its IP address.
Can be used tracert command. It tracks the route of data packets on TCP/IP networks and, therefore, will only work on the computer on which this protocol is installed. At the command prompt, enter tracert 10.0.0.20. The destination will be the name of the remote host. On Unix-like networks, the traceroute command is used for this purpose.
To determine the parameters of the local network, special scanner programs are used. Depending on the complexity, they collect information about network hosts, analyze traffic and test its operation. True, if your computer is in office network, the administrator is unlikely to approve actions to collect such information.

Each computer connected to the Internet has a unique network IP address. There cannot be two computers with the same address on the network at the same time, which makes it possible to determine from which computer a particular activity was carried out.
