"As of this moment, it looks as if the manual Win7 Security-only patch KB 4093108 fixes the phantom NIC bug and static IP zapping bug — but the Monthly Rollup, KB 4093118, does not. That puts us in a surreal situation where Microsoft recommends that those installing the (automatically pushed) Monthly Rollup first install the (manual download) Security-only patch". https://www.computerworld.com/artic...ome-early-crashes-and-a-surreal-solution.html ... I did not install the March W7 Rollup and looks like i won't install the April Rollup because of the NIC bug. Will wait and see if the May Rollup fixes the Nic bug.
