Check this https://technet.microsoft.com/en-us/library/ee617261.aspx.... There is -Oldpassword param which along with -Newpassword param can achieve this. Remember if you are not a Domain Admin then you need to know the old pwd to do this. Plus when you use the -Oldpassword param ,dont use -reset param.
