Microsoft Patch Tuesday, March 2021 Edition

Microsoft today released updates to plug at least 82 security holes in its Windows operating systems and other software. Ten of the 82 vulnerabilities are marked as “critical”, meaning malware or miscreants could use them to seize remote control over unpatched systems with little or no help from users. Yes, good people of the Windows world, it’s time once again to use XEOX!
