Had to disable Spectre mitigation

Since patching my Office HP ProDesk PC with MS and BIOS updates, it was constantly logging this event:

Event 19 Source WHEA-Logger

A corrected hardware error has occurred.

Reported by component: Processor Core

Error Source: Corrected Machine Check

Error Type: Internal parity error

It has also had 6 BSODs with 4 different STOP codes since applying the updates. It doesn't even have the decency to fall over with the same error.

Disabling the Spectre mitigation has stopped the WHEA events (hopefully the STOPs as well, time will tell), by setting the following DWORD to 1:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

REG_DWORD FeatureSettingsOverride = 1

So it seems we have to choose between stability and security, although this at least leaves the Meltdown mitigation in place. Hopefully Intel can push out a less crap microcode update at some point in the near future.
