From the I did not know this about click2run…. courtesy of Diane Poremsky (1), she indicated that Click 2 run inserts tasks into your computer. These tasks will make the system check to see if it’s up to date. Typically one runs at 3 a.m another checks upon logon. So if you run your computer 24/7 click to run will attempt to update at least once at day. Diane indicated that it’s hinted about here: http://office.microsoft.com/en-us/support/office-2013-automatic-updates-are-not-working-HA104022275.aspx whcih tells you to check task scheduler if it’s not updating. There should be two tasks (for c2r) – one checks at 3 am, one checks at logon.
