Intel's microcode update causes random reboots on "Broadwell and Haswell CPUs for both client and data center".

@MrTumnusInfosec Yeah... We have stopped rolling out the microcode update to our VMware hosts - not taking the risk of random reboots over the weekend. Waiting for better info.

My (updated) work laptop had a bluescreen yesterday - haven't seen that with Windows 10 at all, up to now.

now recommends to not install the current microcode upates, or at least not let guests make use of the new commands: "At this point, it has been recommended that VMware remove exposure of the speculative-execution mechanism to virtual machines on ESXi hosts using the affected Intel processors until Intel provides new microcode at a later date."
