    Think I would be asking what in virtualbox is overriding Windows ?


    Nice bit of detective work.
    Are applications allowed to override Windows power settings? I thought the whole point of the powercfg commands was to override the applications' behavior.

    Very good question. Not sure what the rules are around virtualization. You would think Host maintains the role of boss.


    Might be worth documenting to Microsoft in Feedback Hub, could be you've come across a gap.

    As a workaround, I've discovered that within VirtualBox it is possible to block access to specific USB devices. Once I blocked access to the webcam, which I don't need to use within VirtualBox anyway, the entries listed in my OP don't show up when I run powercfg /requests after launching a VirtualBox virtual machine, and the computer sleeps as expected.

    I did a little bit more searching and some people are claiming that "Legacy Kernel Caller" cannot be overridden by powercfg /requestsoverride since Windows 10 version 1809:

    If that's the case then maybe this is just a bug.

    Yeah, I could do that. I really wonder if they read them though.
