How to find Policy serial no. in SEP supporting files

Hi,

Is there any way to find out the policy serial no. of SEP client, if we have already disabled the SEP client icon from SEPM. We have disabled it so that user is not able to disable the sep by hiself/herself. So, is there any way that we can find out the Policy serial no. or group name of sep client among the SEP files, present in system.

Thanks in Advance.
