How to delete Administator Password without any software ? (100% working tip)

Tip 1.
1.) Boot with DOS and delete these files [  sam.log and sam.exe   ] form windows\system32\conifg in your hard drive.
2.) Now when you boot up in NT the password on your built-in administrator account will be deleted ( i.e. No password will be there  )
The limitation is this that you hard drive should be of FAT kind to use this trick  but if you don't have hard disk of FAT type
then proceed to next tip.
you can easily find the file system of your hard drive by right clicking on Bootable drive C: (in my case) and then look for file system. it
is just below the name of your drive.
Tip 2.
1.) Put your hard drive of your computer in any other's PC.
2.) Boot that computer and use your hard disk as a secondary hard disk.(don't boot as primary hard disk otherwise you will not be able to delete password)
3.) Goto location windows->system32->config in your hard disk.
4.) then delete files sam.log and sam.exe
5.) Now remove your hard disk and put it in your PC.
6.) Boot you PC using your hard disk, enjoy :-)
