Hi,
We received a vulnerability alert for enabling Hyper-Threading while we were taking Windows Speculative Execution Configuration Check, what should we do for this?
OS: Microsoft Windows Server 2019 Datacenter
The Vulnerability definition:
Current Settings:
Note: Hyper-Threading disabled.
Looks like to recommend us to enable the registry key for Hyper-Threading? Not sure whether it will impact the VMs running. Any actions or patches can help this?
Cheers,
Bo Xiao

Read on here and also check with the hardware vendor about firmware updates.

Hi DSPatrick,
Thanks for the reply. BTW, there are two recommendations for the settings (currently, not set yet), which one I should choose?
The VMs are based in Azure and the OS is: Microsoft Windows Server 2019 Datacenter
Thanks

Reading here In Azure they've already mitigated.
Microsoft has deployed mitigations across all our cloud services. The infrastructure that runs Azure and isolates customer workloads from each other is protected. This means that a potential attacker using the same infrastructure can’t attack your application using these vulnerabilities.

Either we enable or disable the Hyperthreading in Windows Server 2019 Datacenter version, the vulnerability "Windows Speculative Execution Configuration Check" is not getting Mitigated. Please any one can give an alternate solution?
