Disable Symantec endpoint option is not working on windows 8

Hi ,

We are using SEP 12.1.3001.165 . I applied policy on server side so that user cannot disable the "disable symantec endpoint protection" from client side.

This policy has been applied sucessfully on windows xp sp3 and server 2003 sp2. But it is not working on windows 8 machines. same policy is there same user is log on to the system. refer my snapshot. kindly suggest

.
