It gets worse: Microsoft's Spectre-fixer bricks some AMD PCs

It gets worse: Microsoft's Spectre-fixer bricks some AMD PCs

Some Windows users running devices with CPUs built by AMD, however, report that Microsoft's fix has been freezing their systems. The update was delivered though Windows Update.

Be sure to keep tuned for more updates.

"After several failed boots [it does] a rollback and [then] it shows error 0x800f0845". The "frustrated" user, for example, reports that beyond that laptop, one desktop with a different AMD chip and three laptops with Intel chips have successfully updated.

We recently published an article listing the most frequent issues that users have experienced after installing the latest updates.

Organizations are scrambling to put fixes for the Meltdown and Spectre flaws in place, as makers of operating systems, cloud services, mobile devices and more start to release patches (see Meltdown and Spectre: Patches and Workarounds Appear). The company stresses, however, to wait for the appropriate firmware updates specifically related to Meltdown and Spectre, so as not to download older versions. If not, then users should click the "Software Update" button which should be located just below the summary of the system information.

An emergency fix for the Spectre exploit appears to be causing headaches for people with AMD Athlon-based PCs.

If that wasn't enough, Microsoft also made two changes to its Edge and Internet Explorer browsers to mitigate potential exploits by attacks through JavaScript.

Microsoft also revealed a series of UEFI updates for its Surface products, which are basically coming from Intel since the Surface devices use Intel processors.

"Intel is committed to the industry best practice of responsible disclosure of potential security issues, which is why Intel and other vendors had planned to disclose this issue next week when more software and firmware updates will be available".

The iPhone maker has confirmed all Mac systems and devices running iOS are affected by the vulnerabilities, but also said there are now no known exploits. Even if that is successful, however, the operating system quickly attempts to reinstall the PC-freezing patch, they say.

The faulty design has been present in chips for years and it will force a redesign of the Linux and Windows kernels.
