Urgent!!! What should I do if the username and password suddenly appear when the computer is turned

For this situation,It doesn't matter if the system disk is there.,When you boot up to the login interface, press、Ctrl+Alt+del to see,Is there an admi user for you to choose,If not,I think you're poisoned.。

I didn't set a password but I had a password, so I must have been poisoned and modified the settings of my computer.

There is no disc reload, it seems that you can only go to the market to buy a disc to reload, or the kind of disc with password cracking.

You look for it.,Look for the kind of cracked password U disk version to see.,Burn to the U disk.,Set up from the U disk.,Guide it.。 Otherwise, there is no good way.

When the XP is turned on, press F8 to enter the boot option, select.

Safe mode on behalf of the command line.

2。You will then see a user login-like interface with Administrator

3.Then you'll see a DOS-like interface with :entnetuser

anyone

Space) add

4.After the command is successful, enter :ent

localgroup

administrators

anyone

Space) add

Note that you must put a space box, which is actually creating a user named anyone, with an empty password, and then elevating its permissions to the administrator level.

5。Reboot and you'll see a file called anyone

users without a password. Then you can go to XP.

You can customize this warning box page.,It's not a system error.、It's not BIOS or something.,He just doesn't want others to touch his computer.,That's why he made this screen.、You can click "OK" to go directly to the Windows interface.。

Here's how to make yourself:

Open the Registry window, select the Hkey Lockl Machine Software Microsoft Windows NT CurrentVersion Winlogon subkey in the left column, and create two new string value entries in the right column, and name them "LegalNoticeCaption" and "LegalNoticeText" respectively.

Double-click "LegalNoticeCaption" and enter "System Error" in the pop-up String dialog box

Then double-click the "legalnoticetext" item, and you can enter some more warnings in the "String" dialog box, in short, the more scary the better. When you're done entering, close the Registry. Restart your computer and the warning box will pop up before the login dialog box appears.

In fact, nothing will happen after clicking the "OK" button.

It should be that you pressed the three keys of Ctrl+Ait+Del three times at the same time! Then enter the administrator password empty! Press enter! Enter!

In that interface, press Ctrl+Alt+Delete at the same time to switch to the classic login interface, enter the username administrator, the password is empty, and click to log in.

This, your above sentence makes me very angry, no matter what people say, they are helping you, what do you mean!

To get down to business, it's too simple, you unit that guy can really pretend, bullying novices won't you alt+ctrl hold down and then click delete twice in a row (keypad enter the point of the attachment, number key 3 below).

After entering, see if the username is administration.,Yes, just enter the car and go in.,Delete the password after entering.,Someone will definitely add a password to you! It is recommended to directly put the password on the administration account.,This is the highest administrator account.,After setting the password, you can only have a password if you want to go in (don't forget it).,And then the guy in your unit asked him to come and pretend! If you don't delete the password now, you won't be able to access your computer with a disk or tool!

He's switching users.

LZ told me to get out, I had no choice but to get out.

A: Note: PE is a mini small system, which can rely on the disc and the USB flash drive to boot. The PE system is generally included in the pirated system CD, which is to facilitate the processing of hard disk data when the system completely crashes.

B: Try it with some special password cracking tools, for example, there is an author called "Dusk Messenger", it is very easy to use, you can clear and modify the password without knowing the password, it is integrated on a disc, does not rely on the hard disk system itself to start, you can give it a try.

Use the net user command in safe mode (safe mode with commnd prompt) to add a new user, such as net user aaa add

Then elevate the new user to the administrator permission, for example, net localgroup administrators aaa add

Reboot. Select a new user and delete the original user.

Do you have a system disk?,You can buy a system disk to crack it.。

Dear, this question needs to be analyzed from the following four aspects:

First of all, you need to make sure that your computer is on the network.

Is it normal, sometimes the LAN will have a manual IP address.

Conflict with the auto IP address, if the conflict comes later, the situation you mentioned will occur.

Secondly, the browser settings are not normal, some browsers have set up jump window blocking, or **address blocking, if the blockade is set, you must not be able to log in, and you can't log in.

The third possibility is because of the computer system.

Poisoning, which has led to the unusability of some passwords, one of the earliest worm variants, is specifically designed to steal passwords.

The fourth case is your computer keyboard key wizard.

Look at the keyboard keys input is completely correct, but the login is unsuccessful, and then find that the keyboard keys are out of order, there is a key that always can't be pressed, when typing, it is obviously pressed, but it is not right.

Therefore, it is recommended that you eliminate them one by one from the above methods, so that you can solve this problem as soon as possible.

It should be related to the browser of the computer, or the browser security settings are too high.

The solution is: look at what browser is installed on other people's computers, and yours will also install the same, and lower the level of security settings.

Try it in a different browser, or change the network environment, such as changing the network cable to 4G, I sometimes encounter it, the same ** others can open it, but I can't open it.

Click "Start", enter OK in "Run", and then open:

Computer configuration.

Manage the modal. System login.

Found on the right. Always land with the classics.

attribute disabled OK;

If above. The method cannot be solved, press the following settings:

1. The NetWare client is not installed

1. Click "Local Connection" to open the properties, add "Netware Customer Service" to "Installation", click "Client" and then click "Netware Customer Service" to confirm;

2. After adding "NetWare Customer Service", uninstall it and restart the computer;

3. Click "Start", "Settings", "Control Panel", "User Account", "Change Login Cancellation Method", and check "Enable Welcome Screen".

2. Install the NetWare customer service client

1. Click "Local Connection" to open the properties and uninstall the netware client.

2. Restart the computer, click "Start", "Settings", "Control Panel", "User Account", "Change Login Cancellation Method", and check the Enable Welcome Screen;

Try it, I hope it helps you.

In that interface, press Ctrl+Alt+Delete at the same time to switch to the classic login interface, enter the username administrator, the password is empty, and click to log in.

If you're sure that your password is correct, you've won the bid, so find an antivirus to try.

Or use: You can retrieve the administrator's password.

If you can enter WinXP normally, then log in to WinXP with an account with administrator privileges, and then open the "Control Panel Management Tools Computer Management" (you can also enter to open computer management in "Run"), select "Local Users and Group Users" in the tree list of "Computer Management (Local)" on the right, and you can see all the accounts existing in the current system on the right. Right-click the administrator, select Set Password, and follow the on-screen instructions to reset the password.

If you can't enter WinXP normally, if you can use the command line security mode, then log in with an account with administrative privileges and use net

user command to change the password in the format "net".

useradministrator

Enter your new password", and press enter. If you can't even enter the command-line safe mode, then you can only use the installation disc to select the repair (boot the system with the installation disc, select "Start installing WinXP now" on the installer selection menu, and then select "Repair" to start the repair). The repair process is similar to the win98 overlay installation, the repair will ask you to recreate the password, and the installed software can still be used.

The solution to the account password forgotten:

1. Start the computer, press the F8 key immediately after the boot screen appears, and select "Safe Mode with Command Line".

2. At the end of the running process, enter a DOS-like command prompt interface 3. Type the command: net

usercfansoft

addAdd a new user, the username is "cfansoft", and the password is "123456"; Then use "net."

usercfansoft

active:yes" to activate the cfansoft user; Finally, you can use "net."

localgroup

administrators

cfansoft

add" command to promote the user to the system administration group.

administrators' and make it have super privileges.

4. Restart the computer, select Normal mode to run, and use "cfansoft, 123456" to log in to the computer.

Judging from the screenshot, did it appear when you logged in to a certain background with IE? Then check whether CAPS is open;

There is also the question of whether num is turned on or not.

Does the web page automatically record passwords? A wrong password was recorded...

It's also possible that LZ really forgot the password...

Don't think about changing any settings or anti-virus only.

That would only be a waste of time.

Have you backed up your computer system? If so, restore the system.

If you don't have a backup.

And if you don't have any data on your hard drive.

It's a good idea to format the entire drive.

You can find it by entering the DOS interface!

1. Enter the safe mode to delete SAM files 2. Use a disc or U disk to boot into the menu, and there is a tool that can clear the password.

There is no way, I can only buy a system disk, and there is that function in it!!

In safe mode, switch to guest user mode.
