SEP-Client side process for liveupdate

Hi,

I would like to know which is the process that triggers liveupdate both auto-liveupdate or a manuall liveupdate on client end and also what process is run during auto-liveupdate or a manuall liveupdate.

Basically i am trying to schedule liveupdate in GUP by stopping the client end liveupdate process to prevent update during day time in our environment through SEP.
