For those running default SBS 2003 R2/2008 and 2011 with WSUS – it auto approves security updates to servers and workstations. If you have an 8.1 or R2 deployed in that network, KB2919355 will be automatically approved and probably automatically installed tonight.
Just be aware and watch your patch settings.
2919355 is deemed a critical security update and thus will automatically be installed if you have not changed the settings.
