You mean the user password! If it is a BIOS, you need to disassemble the computer host to discharge the CMOS on the motherboard, which can eliminate the password, but it will also eliminate other information stored in the CMOS. Only the user password is simple!

Method 1: After the login interface appears, press ctrl+alt+del twice. After the classic login interface appears, enter Administractor. The password is empty, so you can generally enter the system and have super permission. Then delete the user whose password you forgot, and it will be OK.

Method 2: Press F8 to select safe mode and start at command prompt. After selecting administrator, the computer will enter the command line window and use the net command to add remote users, such as adding abc. The command is as follows: net user abc /add, and his authority will be upgraded to administrator. The command is as follows: net local group administrator ABC/add, restart, enter with the newly added user name, and delete the forgotten user.
