Microsoft releases optional fix for actively exploited Secure Boot vulnerability

Why it matters: Microsoft has issued guidance for fixing a serious Secure Boot vulnerability that affects all Windows systems and is actively being exploited in the wild. Normally, this kind of issue would be patched via monthly servicing updates but the Redmond company has chosen a phased approach to reduce the risk of you or your organization ending up with devices that won't boot. The fix will require some manual steps for now, but will be applied automatically on all supported Windows systems starting next year.
