Anonymous users2024-02-05I don't know what kind of situation you are referring to when someone has set a username and password? If it is a BIOS setting, it is OK to discharge the CMOS. If you set a username and password into the operating system, you don't know whether you are using Win2000 or XP, if it is Win2000, use the guest identity to access.
If the password is empty, try it. If you can go in, you can set the administrator password inside to a new one. If it is a guest access is prohibited.
Then it's complicated. It's about breaking the code. Enter DOS Boot.
a：\>del %systemroot%\system32\config\sam.i.e. delete the SAM file.
Of course, you can enter the system without any problems. Finally, enter the system, and copy the WindowsePair SAM file to the file directory where you just deleted. If it is an XP system, restart Press F8 to enter safe mode Start Control Panel User Account Find the user you want to change it directly!
