Assuming your parents are too smart, boot up your computer and at login screen press Ctrl + Alt + Delete and a box pops up instead, allowing you to input your own username and password. Just type either "admin" or "administrator" without a password and see if that works. If it doesn't work, try going to some other computer you have access too and get a USB and download Ophcrack onto it and boot up your computer using the USB drive.
