It looks like the security flaw discovered in version 6 to 11 of Internet Explorer was serious enough that Microsoft released an “out-of-band” fix for it. (The company usually releases security patches on the second Tuesday of every month.) This means all supported versions of Windows will be getting the patch. Unusually, Microsoft decided to issue a security update for Windows XP, which they discontinued support for already. This might be a bad move on the company’s part because it encourages its users to keep on using the old operating system. Here’s the link to the security update just in case you haven’t activated automatic update for your Windows OS.
