WHEA-Logger Processor Core Internal Parity Error on 9020

If the registry keys and values don't exist, create them. Alternately, Microsoft has released update KB4078130 to bypass the buggy microcode (I think it basically sets the registry keys for you). You may have to download it manually; I'm not sure if it comes up via Windows Update.

Microsoft recommends manually setting the registry key as described below in order to receive the January 2018
security updates.

Setting the Registry Key

Caution Using Registry Editor incorrectly can cause serious problems that may require you to reinstall
your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of
Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit
the registry, view the "Changing keys and values" help topic in Registry Editor (Regedit.exe) or view the
"Add and delete information in the registry" and "Edit registry data" help topics in Regedt32.exe.

Note: Customers will not receive the January 2018 security updates (or any subsequent security updates)
and will not be protected from security vulnerabilities unless their antivirus software vendor sets the
following registry key:

Key="HKEY_LOCAL_MACHINE" Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat" **bleep**="cadca5fe-87d3-4b96-b7fb-a231484277cc" Type="REG_DWORD”
Data="0x00000000”
