How to know the password without turning on the computer and how to simply crack the computer boot password.
First: This is the simplest method. When logging in, the system defaults to XP system. You choose to enter the DOS tool before entering, and you have the option to cancel the user password directly. This is what experts learned, and it is suitable for the situation that you can't enter in safe mode. We know that in the process of installing Windows XP, you will log in with "administrator" by default, and then you will be asked to create a new account, so that you can log in with this new account when you enter Windows XP. Moreover, only the established user account will appear in the login interface of Windows XP, and "Administrator" will not appear, but in fact, the "Administrator" account still exists and the password is empty. When we know this, if we forget the login password, on the login interface, hold down the Ctrl+Alt key, and then hold down the Del key twice, and a classic login screen will appear. At this time, enter "administrator" in the user name, and the password will be blank, and then modify the password of "zhangbp". The second method: 1, delete the sam file-this method is effective for win2000, not only for xp and 2003, but also for system deadlock.
It's completely unusable. N7e 2, use winpe to boot into the console, and then use dos command to manually add users-unless the original administrator password is not set, it is invalid. Cmd.exe changed its name to logon.scr (of course, it should be hung on another machine), V2=k 3, and the screensaver changed its name. After the boot, you waited 10 minutes before entering the screen saver. In fact, when you enter the dos command line interface, you can add users by command-it has been proved in sp 1, sp2, 2003 that the authority after entering dos is not an administrator at all. ? F 4, hang the hard disk on another machine, take out the sam file and decrypt it violently with lc4-theoretically, but if the password is complicated, the decryption time will be longer than bt. K` 5, use Windows Key floppy disk to start the system, and you can directly modify the administrator password. There are two places to set passwords in CMOS. One is the advanced user password and the other is the ordinary user password. When the computer starts, it will ask for a password, and the computer can start by answering one of the passwords. If you want to enter CMOS settings, you need a high-level user password. Computers treat CMOS settings as highly confidential to prevent others from messing up.
Change, and the authority of high-order password is higher than that of user password in CMOS settings. Simply put, if both passwords are set, you can use the high-order password to enter the working state or CMOS settings, while the user password can only enter the working state or enter CMOS to modify the user's own password, and no other settings can be made for CMOS. If only one password is set, no matter who it is, there will be two permissions. Move the cursor to the password setting, press enter, enter the password, and then press Enter. The computer prompts you to re-enter your password for confirmation, and then press enter. If you want to cancel the password you set, when prompted for the password, just press Enter. When prompted to cancel the password, press any key and the password will be cancelled. Pay special attention. Once the password is set, remember it firmly. If you set the power-on password for the computer and forget it, you can't work with the computer, which will delay things. If you really forget the password, you can't start the computer. For an expert, you can make the computer forget the password by disassembling the computer host and discharging it with CMOS, but this can only be done by looking for someone who is very familiar with the computer hardware and referring to the motherboard manual. Moreover, when CMOS forgets the password, it will forget all the settings and must be reset. Better remember the password!
High-order password is the content of SUPERVISON password in CMOS, and general user password is the user password in CMOS. There are two places to set the password. One is the advanced user password and the other is the ordinary user password. If a password is set in the BIOS, COMS will be discharged, and if it is a Windows login password, the system will be recharged. The computer's power-on password, like the email password, cannot be known and read. You can handle Sam. The power-on password of the computer is stored in the SAM file, which can be cracked by the software that cracked SAM or read by the software. You can read power-on password, email password, online account and so on. . . You can contact me if you want. Luqiao 520@ 163. Well, we need to know what the startup password you set is. If it's a BIOS password, it's annoying and you can't get into the operating system. It can only be cracked by discharge. If it's 98, it's easy. Press ESC at startup to jump into the system. Then enter the WINDOWS system folder, find the file with the suffix PWF, delete it, and re-enter the password when you enter 98. However, this file is a system file, so it should be set to show all files in the folder option.
