The quality of March’s patches set new lows, even by Windows’ tarnished standards. The Win10 patches flew fast and furious, with new Microsoft-induced bugs introduced and swatted multiple times over the month. The Word 2016 security patch demands that you first install the Word 2016 non-security patch, or Word refuses to open files. That bug hasn’t been fixed. Windows 8.1/Server 2012R2 escaped relatively unscathed. Server 2008 got a fix for its buggy patch, KB 4090450, on April 3. But Windows 7… ah, that’s a dying horse of a completely different color.
