Hey Windows (ab)users! Microsoft patched around 200 vulnerabilities in Windows etc today, a record Patch Tuesday batch. All indications are they fixed two of the zero-days dropped last month by the researcher Nightmare Eclipse, including "Green Plasma" and the "YellowKey" exploit that allowed local access to data encrypted by BitLocker. In response to today's Patch Tuesday, Nightmare Eclipse dropped an exploit for what they claimed was a zero-day bug in Windows Defender.

Nearly three dozen of the bugs patched this month earned Microsoft’s most dire “critical” rating, and exploit code for at least three of the weaknesses is now publicly available.
