2. What should I do if I turn on the computer and suddenly prompt for my user name and password?
First, if you know the user name and password, enter it directly and press enter to enter the system.
Second, if you forget your username and password, you can use the USB flash drive to enter the PE to clear the computer boot password. These steps are as follows
Preparation: an ordinary computer and a USB flash drive.
1, Baidu downloads "Master U" (peaches and cabbages can also be used), and downloads and installs this software on the computer.
2. Plug in the USB flash drive, select a key to start the USB flash drive (before making, clear all data and the USB flash drive will be formatted), and wait for completion.
3. Insert the U disk into the computer where the system is to be installed, and press delete(F 12, F2, F9, which is slightly different according to different computers) to enter BOIS settings, and set the first boot device as USB (some boot) in the boot item (or press F 10 to save the word with USB).
4. Enter the PE, and select the one-click computer password clearing tool on the desktop.
3. What if the password is entered correctly, but the computer shows that the password is wrong?
The password is entered correctly, but the computer shows the password is wrong. The possible reasons are as follows:
Opening the (1)caps lock key will cause all lowercase letters in the password to become uppercase letters, resulting in an error. It is recommended to switch the locking mode and try again.
(2) turning on the NumLock key will cause the numbers in the password to be unable to be entered on the keyboard, resulting in an error. It is recommended to switch locking mode and try again.
Password is a confusing technology, hoping to turn normal (identifiable) information into unrecognizable information. Of course, for a small number of people, these unrecognizable information can be reprocessed and recovered. Password is a general term for "password" in Chinese.
In fact, the "password" entered when logging in to websites, e-mails and withdrawing money from banks should be strictly called "password" because it is not the original "encryption code", but it can also be called a secret number. A symbolic system (such as a message) that is mainly limited to personal understanding. Such as cipher telegrams and cipher typewriters.
Password is a symbol compiled according to a specific law, which is used to transmit the information of both parties. In other words, a password is a series of symbols that hide the real content. It changes the information expressed by an open and standard information code into an information code that can't be read by anyone except the two communication parties through a transformation method. This unique information code is a password.
Cryptography is a science with a long history. In ancient times, passwords were used to transmit secret information. In modern wars, the transmission of information and the command of war are inseparable from passwords, and so is the diplomatic struggle. Passwords are generally used for the confidentiality of information communication transmission and storage.
With the development of computer and information technology, the development of cryptography is also very rapid, and its application field is also expanding. Passwords are not only used for information encryption, but also for data information signature and security authentication. In this way, the application of cryptography is no longer limited to serving military and diplomatic struggles, but is widely used in social and economic activities.
Nowadays, there has been a trend of socialization and personalization of password application in the world. For example, cryptographic technology can be applied to e-commerce to identify the identities and commercial credits of both parties in online transactions and prevent "hackers" and fraud in online e-commerce; When it is applied to VAT invoices, it can prevent forgery and tampering, put an end to all kinds of acts of stealing, leaking, escaping and defrauding state taxes by using VAT invoices, and greatly facilitate tax inspection; When it is applied to the identification of bank checks, it can greatly reduce the financial crime of financial fraud by using fake checks; When applied to personal mobile communication, it greatly enhances the confidentiality of communication information and so on.
4. What if the user name and password are displayed when the system is turned on?
Ignore the password and just click OK to try?
If you can enter, you can change "Change User Login or Logout Mode" in Control Panel-Accounts.
.
If this doesn't work, you have to enter the power-on password, which will be troublesome. Did someone know your power-on password and deliberately changed it? Or you were infected with Trojan virus and secretly changed your power-on password.
At present, both Ghost installation disk and U disk startup disk have their own software/function to modify the system password. Want to crack (change) the system boot password, basically can only rely on these two things.
So either go outside and buy a Ghost version of the installation CD (a few dollars), or borrow someone else's computer to make a USB flash drive. The PE system in them has its own software/function to modify the system boot password, just adjust them to the first boot item, so you can modify the boot password yourself.
For beginners, the difficulty lies in how to adjust the CD-ROM drive or USB flash drive as the first startup item in the motherboard bios. )
If you really don't know how to operate it and are afraid of damaging the system, take the machine outside to repair the computer and let others help you repair it. Charge 10-20 yuan, they will fix it in 30 seconds.

The so-called methods on the Internet, such as pressing F8 to enter the security mode to change the password or create a new account, simply won't work, because if you have a password when you turn on the computer, you still have to enter the password before entering the desktop. Without this password security mode, the system can't enter. How can you change the password? These are all rumors and have no practical use at all.
As for the method of fastening the motherboard battery, it is completely ineffective. Because the boot password is stored in the hard disk, deducting the motherboard battery only restores the motherboard bios to the factory state, which has nothing to do with the hard disk!

I have been engaged in the computer industry for ten years and know a little about everything. You can ask directly if you have any questions.
