Windows 7 SP1 Slow Installation Issues (Symantec Endpoint Protection)

I came across and issue today with SP1 for Windows 7 taking forever to install.

Installation was running but progress bar stopped at about 50% for about 1h30mins (probably longer if I hadn’t got impatient). I checked taskmanager and the trusted installed was running and using CPU about 7%.

I had this running on two laptops and both were exhibiting the same symptions, after some fustration I disabled SEP by right clicking the icon and choosing disable and then the flood gates were opened and both laptops whipped through the rest of the installation.
