Microsoft halted security patches against Meltdown and Spectre as AMD customers report problems of
Microsoft security patches to mitigate against Meltdown and Spectre chip vulnerabilities are now slowing down PCs and servers. According to Reuters, Microsoft said on Tuesday that software patches released to guard against CPU security threats slowed down some PCs and servers, with computers running on older Intel processors seeing a noticeable decrease in performance. In a notice released on its website, Microsoft explained, “The compatibility issue arises when antivirus applications make unsupported calls into Windows kernel memory. These calls may cause stop errors (also known as blue screen errors) that make the device unable to boot.”

Microsoft also issued updates for AMD devices, but has had to put the delivery of the patch on pause following a slew of complaints from customers on its support channels.
