Meldown and Spectre F

Hi

Microsoft issue a fix to Meltdown and Spectre vulnerabilities 

https://support.microsoft.com/en-us/help/4072698/windows-server-guidance-to-protect-against-the-speculative-execution

There are some reports that AV software can cause BSOD if a key in the registry is not updated 

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

Is there any update from Sophos
