What are the default usernames and groups, and what are the default usernames for win7

You can see Administrative Tools - Computer Management - Local Users and Groups.

The main ones are these:

Administrator group: The Administrators group, whose members have full control over the local computer, is the only group in the system that is given all the built-in permissions and capabilities.

Backup Operators Group: A backup operator group whose members can back up or restore files on their computers, and can log on or shut down the system, but cannot change any security settings.

Power Users group: A standard group of users who can change computer settings and installers, but can't view documents created by other users.

Users group: A restricted group of users who can run programs and save documents, but cannot change computer settings, install programs, or view documents created by other users.

Guests group: A guest working group that allows casual users to log on to their computers using guests, and they are given minimal privileges. Users in the guests group can shut down the system.

Replicator Group: This group supports directory replication, and only members of the replicator group can log in to the backup server of the domain controller using domain users.

1. Built-in ordinary group:

administrators belong to the mainland users of the local group of administators, all of whom have system administrator permissions, and they have the greatest control over the computer, which means that they can perform the management tasks of the entire computer. The built-in system administrator is a member of the local group, and it cannot be removed from the group.

2. Built-in special group:

EverOne any user belongs to this group period. Important, just like if the guest account is enabled, you have to be careful when assigning permissions to the everone group, because when a user who does not have (as opposed to) an account connects to the computer, it is allowed to automatically connect with the guest account, but because the guest also belongs to the everone group, it will have all the rights that everyone has.

The default username for win7 is administrator;

The administrator is a super administrator or super user of the system and has the highest administrative privileges on the system.

You can change the default username as follows:

1. Select the computer on the desktop, right-click and select Manage;

2. Local users and groups - users, select administrator on the right, right-click and rename, and enter a new user name;

3. Restart the computer to take effect.

Win7 and XP are both Administrators, except for the Home Edition, of course. The Ultimate and Pro versions are the ones that are this.

The default username for almost all Windows systems you come across is administrator

The username of your installation, or the superuser administrator

Yes, this tells you which computers are in your workgroup or in a group in your domain, and if your group has a special permission setting, then every user in the group has this setting. If you delete a user, you may lose that permission, so you need to think about it.

However, even if you have deleted it, you can still add it.

That might just be the only way to disable the account.

You can deactivate the redundant account, and the system account cannot be deleted.

Start Run Input: netplwiz Press the enter key and open the user account to manage (usernames and groups here).

You can delete a username that is not your own, but administrator and guest are the default accounts and cannot be deleted.

The groups in the account are the default of the system, and different groups have special permissions, so it is not appropriate to delete them without authorization.

The reason why the "Unable to run this operation on the built-in account" prompt appears when deleting is that the user does not have permission to delete.

root nobody, these must be there Because the system defaults to many users running with these accounts, you can enter the system and enter vipw to see all the accounts.

People in the city can communicate with me directly about linux in the future

You have to look at the system, the system is different, the default username will be different, but root is basically what all systems have.

Yes, it is recommended to keep only the administrator user as follows:

1. Click Start, click Run;

2. Enter and click OK;

3. Click Local Users & Groups - Users;

4. The list on the right first ensures that administrator is enabled (if it is not enabled, double-click to pop up a dialog box and remove the checkmark that the account is disabled);

5. Restart the computer and click Administrator to log in;

6. Run it again, enter User Management, right-click on other users, and click Delete.

There are a lot of groups, and the default user seems to be three, administrator guest user you created.

If it is the first time to log in and you apply for registration online, the username is the bank card number, and the password is the bank card password.

If you have already opened online banking at the bank, and you have registered another alphabet at that time, that is the username of the online bank, and the password is the card password. After logging in, you can change another password, if you do not have a registered user name, you can directly log in with the card number account password.

Mine is also ICBC card, you are sure that you have opened online banking in the bank, you can log in with the card number and original password, but the bank should give you a password to protect the card or other U shield to help secure login, and you must also install controls before logging in.

If you are not sure about opening online banking, you can log in to ICBC**, register and open it with the card number and password, but you may not be able to transfer money without a password card. If you do open it, and you can't log in with the card number and password for installation controls, etc., you can call 95588 ICBC service **call** for consultation.

ICBC's online banking login username settings are as follows:

1. Card number + password.

2. Username + password, the username is what you refer to with letters, the setting rule is 6-15 characters, and the characters can be letters, numbers or symbols; The setting method is: log in to online banking - customer service - personalized customization.

I opened the online banking of the Bank of Communications, the username is the first 6 digits of the card + the username registered in the online banking, I don't know what bank's online banking you are, or call the bank** to ask.

The second brother and the Bahar master's scholar, Adolf Assad, sent the place instead.

I want to log in to railway 12306 but I want a username. I don't know how to get on. What is a username and how to write it?

Ask: Win7 local users and groups in the group have 14 names, do outsiders enter the system through these groups?

The rest of the admin should be able to be deleted, and the consequences are no, that's just logging in to the profile, which is which number you log in, and all the settings of your account are saved in the settings of the other number, which is not the same as the settings of another number.

Windows users and groups are a permission-based approach to system management. In many cases, "users" or "groups" are used when different operation permissions are involved.

For example, common groups include administrators, users, powerusers, and guests for user permission hierarchy, and backupoperators, event-logreaders, etc., for system configuration management.

There are also some for software management, such as IIS IUSRS, etc., which are enabled by default by installing platforms such as IIS or SQL Server, which can facilitate better access to software or better management and maintenance.

The user, on the other hand, is subordinate to the group and inherits permissions from the group. For example, there are common built-in users administrator (system super administrator) and guest (guest, disabled by default).

Users and groups can be created freely, and the creator can also delete the created groups or users. In other words, you can delete only those created by a user role. But beware:

1.Built-in or default "groups" (including administrators, backupoperators, cryptographic operators, distributed com users, guests, IIS iusrs, network configuration operators, performance log users, Performance Monitor Users, Power Users, Remote Desktop Users, ReplicatorUsers) cannot be deleted, which can be understood as the built-in group is created for the system, and the system account is system, and his authority is above all accounts, even administrators.

2.For "users", except for administrator and guest, which cannot be deleted, the rest can be deactivated, and all users can be deactivated (not deleted), as long as there is at least one administrator account (including super administrators) belonging to the "administratos group" in the system, otherwise the system will lose control.

3.If you delete a related group, users who belong to the group lose their administrative or usage rights. In addition, groups or users created by the user cannot be restored once they are deleted.

The default user group has a certain permission, and it is not recommended to delete it, and the deletion must fail, and it is not just a problem.

These usernames should belong to the built-in security topic, it may not be an actual user, I may understand it this way, it may be wrong, but you can find a lot of such users in the advanced options of adding users to the group, you can delete the current few users, and then add them back.

The user, on the other hand, is subordinate to the group and inherits permissions from the group. For example, there are common built-in users administrator (system super administrator) and guest (guest, disabled by default). Users and groups can be created freely.
