Instead, it's the resulting patches that are causing most of the problems, including performance issues and random reboots. To deal with the latter, Microsoft has issued an out-of-band security update for Windows. >Random reboots are not just an inconvenience, they can corrupt data and lead to data loss. That's especially problematic for mission critical PCs. Unfortunately, Intel's first round of patches designed to mitigate Spectre and Meltdown were found to be buggy, causing some systems to reboot at random times.
