In case you haven’t heard, Microsoft released an emergency patch yesterday afternoon for the bad Internet Explorer bug that prompted the Department of Homeland Security to tell everyone not to use IE until further notice. That was no surprise, given the amount of publicity behind this bug.
What was a surprise was that they went ahead and released the patch for Windows XP as well. So, unless something really weird happens, the very last patch for Windows XP is MS14-021, issued 1 May 2014.
If you run Windows and your PC didn’t tell you this morning it applied updates automatically, go to Automatic Updates in Control Panel and download the fix.
