Some Intel CPU models are affected by a bug that crashes computers when a certain sequence of operations are being processed. The bug was discovered by a developer working on the OCaml compiler and was reported to Intel last year. Intel rolled out a fix for the bug in April and May 2017, but there’s no sign of the bugfix in Windows updates. Experts recommend that users disable hyper-threading in their BIOS or UEFI settings, which mitigates the bug but at the cost of CPU performance.
