Office 2013 Home and Business with WSUS

Hi,

My company acquired 50 licences of Office 2013 Home and Business a few months ago, and I've discovered the Click-2-run technology to keep O2013 up-to-date.

This morning, I've installed a new laptop as usual, including O2013 and our config to reach our WSUS server.

What surprises me is that, one hour later, Windows Update offers me to install 43 updates, all concerning O2013.

I'm pretty sure that no O2013 H&B update should come through WSUS, especially because of click-2-run.

Do you have any information about this specific case ?

Thank you for your help.
