How to delete SAM file without Access?

Asslam.o.alaikum;

i would like to ask that how one can delete SAM file of OS without logging in to administrator account using MS-DOS? IS there any way For example if someone has forgotten the password and might log on to guest account and delete SAM file to re-enter in Admin account?

Thanks and Regards,

Deleting SAM file will probably kill your windows installation or prevent you from logging onto any account altogether. There are many utilities to reset the admin password for windows, usually requiring a boot-cd or bootable usb. Try one of those (Google) to reset (blank) the admin password.
