Description :  
                     I create this program using a simple xp dos command line bug . You can change pass without old pass  from command prompt . Command is below  here .

                                               net user *username *newpass  
*username= your computer current user  and *newpass = new password .
In my program at first scan computer username from computer using  GetUserName(); function and scan new password from user .

   I  Manipulate a string like as command line command and use this as dos command by system() function.
