Microsoft issued a fix on Thursday for a security flaw in Internet Explorer that led the Department of Homeland Security to suggest users change browsers until the problem was solved. The fix updates the computers of all users of the Windows operating system who have automatic updates turned on, the company said on its security response page. For those that don’t have the updates enabled, “now is the time,” wrote Dustin Childs, with the response communications team at Microsoft.
To turn it on, users should click on the “Check for Updates” button on the Windows Update portion of their Control Panel.”For those manually updating, we strongly encourage you to apply this update as quickly as possible following the directions in the released security bulletin,” Childs said. The fix is surprising because it also includes code for the Windows XP operating system, which Microsoft officially stopped supporting on April 8.
