Trusted Root Certificates Out of Date, Update?

Hello, this is my first post and while I have some experience with IT I beg your forbearance if I don't automatically understand some terms. Okay, I ran WSUS for the first time today and was pleasantly surprised at how powerful the program was, essentially it offered everything I needed which was to allow me to save time (following a new pc build) to update Windows, Service Packs etc, C++, Office etc. WSUS also allowed me to choose an external USB drive to save the data to.
Prior to starting the program I ran Windows Updates and ensured the system was up to date so was surprised and I must admit a little dismayed to discover that WSUS stated my Trusted Root Certificates were out of date, with trepidation I exited the program created a Restore Point and started again, this time hitting 'yes' for updating the certificates.
Now, my question is this; WSUS updated certificates from march 2014, not the 23rd February 2015 so I have to ask am I in trouble? Will I have to re-update all my WIndows Updates?
Thanks in advance
