To "hide" KB2778344:
On the Desktop, right-click the Action Center icon on the taskbar > Open Windows Update > Change settings and under "Important updates" choose "Check for updates but let me choose whether to download and install them" and, if you wish, check "Recommended
updates" and "Microsoft update" > OK
