What's worse than the chip flaws that leak sensitive information? Apparently, some of the software updates meant to fix them.

Over the weekend, Microsoft released an update that disables a patch to Intel CPUs after reports that the patch -- meant to fix a design flaw known as Spectre -- caused unexpected reboots and other other problems. Intel called a halt to installations of the patch one week ago, but Microsoft's new update goes a step further and disables the patches on any computers that already had them installed.
