Microsoft Windows users:

Yesterday was Patch Tuesday, so you probably have a notification that you have updates waiting.  Please do yourself a favor and apply the updates as soon as possible.  This time Microsoft patched a problem that has been known for over 13 months.

Why is it important to apply updates immediately?

The patches that are released are for issues that only Microsoft can fix inside Windows.  Your antivirus can’t protect you from these types of problems.
