How to 'Hack' into any Computer as an Administrator Without a Password

This is my tutorial, you may see it placed in other places by other users because of how simple it is. I haven't seen this in a while, thought I would share it with the noobs.

Please, no flame.

YOU NEED PHYSICAL ACCESS TO THE COMPUTER TO DO THIS!

Anyway, how to hack into a computer as an administrator without the password:

Step 1: Turn the computer on.
Step 2: Spam F12 a bunch of times, until the advanced startup menu comes up.
Step 3: Boot the computer into safe mode.
Step 4: Log into the account called "Administrator". There's a 99% chance that the account will not have a password.
Step 5: Go into the control panel, change the administrator's account password.
Step 6: Reboot normally.
Step 7: Use the password you put in with the administrator account you targeted.
Step 8: Enjoy!

PS: I've only tested this on XP, not sure about Vista or any other OS.
PPS: If they have the "Enter your username and password" login thing, then push Ctrl + Alt + Delete to go to the other log in screen.

If this didn't work, I recommend learning how to not be a noob.
