For those users which don't have Automatic Updates on Windows running and use the Windows Updates site to manually scan and update their Windows computers each month on "Patch Tuesday", please note there is a need to run a second scan and update for the February round of updates. During the first scan and series of updates, in addition to all the other patches mentioned in Carol's list above, there is a "Critical" cumulative update for Internet Explorer which pops up. (For example, on all our Windows 7 machines with IE11, the update is KB3021952) After the installation of all the first series of updates, a restart is needed.
After restarting the computer, you'll need to run another Windows Updates scan at the website. When doing so, a second Internet Explorer update will show up which didn't appear during the first scan. (This time, our Windows 7 computers with IE11 had a secondary update KB3034196) The second update is an "Important" update which patches a vulnerability in the "jscript9.dll".) According to the MS15-09 Security Bulletin in question, it appears like this should happen on IE versions 9, 10, and 11.
I'll guess that those with Automatic Updates enabled, they will see the secondary update popup shortly after the first set are installed.
Hope this helps.
