If you wana change someone's login password even if you don't know his/her password, here is a small command and you can use it to change his/her login password. All you need is his/her logged in system. Just go to command prompt and enter the following code 1 net user (enter) 2 net user owner(name of the owner) * (enter) 3 feed the new password 4 confirm new password 5 exit

In that case, is there any way one can find out if someone changes his/her password? What could be done to prevent one's account from being hacked this way?
