SCCM Windows Updates Delayed Install

[gobigblu9]

Guys I am trying to figure out something that has happened in the last week that's never happened before. A bunch of our laptops received windows updates this past Tuesday out of the blue. When I go search in programs and features and look at the updates that were installed I can see these were patches we pushed out months ago. I know for a fact even on my own machine that I had a successful deployment (at least according to deployment monitoring) for the particular software update group. Is it possible for a client to get out of sync and send the wrong message to WSUS kicking off a reinstall? I've never seen anything like this. Any ideas would be appreciated.
