Looking for more of a suggestion here, than a solution. Wondering if there is a "rule of thumb" when it comes to approving updates for installation via WSUS, based on year. If a certain update is relevant to a particular system, how far back should I go in time when approving.
For instance, If I have updates that are from 2006, should I approve them anyway, despite that in all likelihood, they've probably been installed already either manually or automatically, 8 years ago (this being 2014). Or, should I approve everything where appropriate hardware and OS-wise, and ignore the year of issue.
