Windows XP power-on password forgot what to do?

If your Windows administrator is not the administrator of the system, and you do not have a password, you can press the CTRL, ALT, and Del Keys two times on the boot. Use the administrator to enter the system and modify the password of your original admin.

There is another way. Press F8 to enter the Safe Mode with command line when booting. Enter the following command.

NET user xx (password)/add (set up a new account called XX, the password is the account you want to set the password, do not fill it does not matter)

net localgroup Administrators Xx/add (upgrade XX to Administrator rights)

Shutdown-r (reboot)

Then you will find that your user has one more xx, you can use this user to log in to Windows and modify your previous admin password.
