    Hi Charley Peck,

    The Hyper-V feature could have been removed from the running operating system. You can restore the removed feature from a specified source using DISM.

    Dism /Online /Enable-Feature /FeatureName:Microsoft-Hyper-V /All

    Please refer to this link for more details.

    Best Regards,
