Microsoft has released an update that patches the most recent Internet Explorer vulnerability for all versions of Windows. Although Windows XP is no longer supported, Microsoft has made and exception for this particular update. If you have automatic updates turned on, you will get this new update without having to do anything. If you haven’t turned on automatic updates, you should do so now. Click the “Check for Updates” button on the Windows Update portion of your Control Panel.
