I always keep my systems on the network updated with the latest Windows Updates. However, in the case of a 3CX PBX system, I completely update the system before installing 3CX, but then leave it alone after that. My thought is the PBX is working and configured, this is the only purpose of this particular system, and introducing new updates will only increase the chances of breaking something. So with that in mind, I was wondering what others did, and their thoughts on the matter. Do you regularly apply Windows Updates to your systems after 3CX installation?
