Microsoft Pauses Meltdown Patches For Some AMD Processors, Blames AMD

In a statement, Microsoft blamed AMD, saying the chip maker screwed up its documentation for the Windows security patches for the chip flaws, called "Spectre" and "Meltdown".

Microsoft said it will temporarily stop sending the nine systems updates out to some PCs running particular AMD processors.

After Microsoft recently confirmed that it is mitigating the Meltdown vulnerability with automatic updates, reports have fallen in that Microsoft's fix for the bug, may be crocking AMD-powered PCs.

Microsoft's report, issued Tuesday morning, triggered an immediate dip in Intel shares, which had already fallen 4.5 percent since word of the security problems leaked out last week.

For now, Microsoft has stopped the distribution of this update to PCs with AMD processors.

There is also a tripod mount on the bottom, so you could theoretically mount it on a tripod and get some really stable images. Powered by the Snapdragon 835 VR platform, Lenovo's Mirage Solo comes with a QHD display and weighs only 645 grams.

Microsoft said that it is still testing the speed impacts of updating systems, and it doesn't have concrete numbers yet. Those who choose to install the fixes and then have to buy more servers to get their performance back to where it once was are likely to be particularly unhappy. Intel's business is built around offering measurably better computing performance for more intensive tasks, such as streaming or editing video, playing online games, or working with large data files.

Intel's shares sank in the two days after the chip vulnerabilities were disclosed last week, while AMD shares are up more than 15% since January 2, the day before news of the security flaws was widely disclosed.

If you have not been offered the security update, you may be running incompatible antivirus software, and you should consult the software vendor. However, for Windows 10 PCs with Intel Haswell CPUs or older as well Windows 8 and 7 systems using these same old processors, the performance impact will be much more significant.

Allen Falcon, CEO of Cumulus Global, a Westborough, Mass. -based cloud solution provider, hasn't come across any AMD-related performance issues among his company's customers. Hardware OEMs and OS manufactures have banded together to release patches to help mitigate the effects of any attacks based on Meltdown or Spectre, although some of those patches have been disastrous.

As if the Meltdown and Spectre processor security bugs that have been dominating headlines across the internet for the past week weren't scary enough on their own, even the patches for those bugs are causing problems now. However, patch issued by Microsoft appears to have done more harm than good at this stage.
