    Undervolting with hypervisor / virtual machine for WSL2


    Hi MS community,I'd like to undervolt my CPU while running CFD on a laptop. The reduction in core temperatures achievable with an undervolt improves performance by limiting or eliminating throttling. I have found that Windows 11 appears to restrict the ability of software like Intel's XTU or throttlestop from controlling core voltages.Can you please advise how this feature can be disabled, while retaining the hypervisor / virtual machine functions of windows? I require the latter as the CFD code runs on linux, which I have operating in WSL 2.

    :)

    WSL2 for windows

    I have failed into installing WSL for Windows. I have read here: https://docs.microsoft.com/en-us/win.../install-win10 how to do it, and at step 4:


    1. Download the latest package:
      [COLOR=var(--text)][COLOR=var(--info-dark)] Note[/COLOR]
      If you're using an ARM64 machine, please download the ARM64 package instead. If you're not sure what kind of machine you have, open Command Prompt or PowerShell and enter: systeminfo | find "System Type".
      [/COLOR]
    2. Run the update package downloaded in the previous step. (Double-click to run - you will be prompted for elevated permissions, select ‘yes’ to approve this installation.)

    I encountered:

    and

    What I did wrong ? I have the following W10 version:

    Undervolting with hypervisor / virtual machine for WSL2

    Firewall between host and Hypervisor manager virtual machine.

    I have created a virtual machine. I would like to protect my computer (the host) from any malicious programs on the virtual machine (viruses or other malware). How would I go about doing this? Do I need to make new rules against Hypervisor manager
    in the firewall settings? can I just create a completely new firewall just for the virtual machine? Should I protect my device with something other than a Firewall? I am relatively new to virtual machines in practice, and would like to know more about them
    in the security field.
