MS security bulletin MS14-025 ,password still getting applied through GPO

Dear All,

We used to use group policy for distributing and standardization of local administrator password through GPO,my security team found out its not a best practice since Vulnerability in Group Policy Preferences Could Allow Elevation of Privilege, for this, i applied the below patch on all my DCs 

https://technet.microsoft.com/library/security/ms14-025

and i changed the local administrator password  for couple of servers to test if the old GPO password policy gets applied to the server,i found even after changing the local administrator password the password from GPO still gets applied.

Regards

JAck.
