Event ID 1014: HyperThreading - dcasota/Lenovo83BY GitHub Wiki

Windows11 throws a warning:
The hypervisor did not enable mitigations for side channel vulnerabilities for virtual machines because HyperThreading is enabled. To enable mitigations for virtual machines, disable HyperThreading.

Disabling HyperThreading on Windows 11 typically requires changes in the BIOS/UEFI settings, as HyperThreading is a hardware-level feature. However, you can use PowerShell to adjust certain registry settings related to side-channel vulnerability mitigations. Here's how you can proceed:

Open PowerShell with administrative privileges.

Run the following commands to modify the registry keys:

# Disable HyperThreading-related mitigations
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" -Name "FeatureSettingsOverride" -Value 8264
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" -Name "FeatureSettingsOverrideMask" -Value 3

Restart your computer for the changes to take effect.

Keep in mind that these commands adjust mitigations but do not directly disable HyperThreading. To fully disable HyperThreading, you need to access your system's BIOS/UEFI settings during startup and look for an option related to "HyperThreading" or "Intel Hyper-Threading Technology." Disable it there.
