As of Tuesday, Jan. 12, Internet Explorer versions prior to IE11 reach their "end of life" (EOL).
This means they will no longer receive any updates or security fixes.

If you are using IEs older than 11 on Win7/Server 2008R2, Windows Update KB3124275 will install a "nag" message.

If you are still an IE user, you should upgrade to IE11 ASAP.
Make sure to run Windows Update after upgrading to IE11.
