We know that for change the password of the another accounts, we must for first, write his corrently password. Now i tell you how to change the password of another account, without knowing the corrently password. So, in the DOS, write this:
"net users" (P.S. without the ")
then u can see:
Administrator
Guest etc;
then this, you must write:
"net users name_of_account *" exampol: net users John * (WARNING: beetwen to John and * you MUST press a space)
and then write new passwrod.
cheers
