Here’s what to look for: Office 2013 SP1 installs at Version. The reality is, that even when you do your best to make sure that all your systems are patched, and updates are approved on time, there can still be stragglers out there that haven’t been receiving their updates – and sometimes can be YEARS behind! Well, we both know that’s not quite the case, as you’re still reading ).
