Following the criticisms made by AMD's representatives, who accused Microsoft of indiscriminately applying a patch of security that could unduly diminish performance for PCs that are not targeted by Meltdown exploitation, things seem to have taken an ugly turn, some of the PCs equipped with AMD processors just stop working at all.
With the full name KB4056892 (2018-01) Cumulative Update, the patch designed to limit the effects of Specter and Meltdown exploits, the latter targeting only PCs equipped with Intel processors, seems to come up with its own set of problems, so that Microsoft temporarily suspends the updates delivered through the Windows Update service.
In a first official statement, Microsoft accuses AMD of failing to provide the documentation necessary to ensure compatibility with all the chipsets and processors in circulation. Nothing about the Microsoft team's responsibility to concretely test their own patches, also using AMD-based PCs.
Meanwhile, AMD has announced its direct involvement in developing a new patch with Microsoft, which is due to be distributed at the end of this week. If they will successful partner together even if they are competitors, will need to see. Nevertheless we see many failed updates within biggest companies and we are wondering this days how they ensure the security and quality of their products, as it seems that these are not at high standards anymore. And all this just harms the brand and opens up doors for others to enter targeting what the others are missing.
