    You are using Virtual Machine by LXZ compression files, you need look inside the OS properties Storage space..

    Who talked of virtual machines?
    This is baremetal.
    Anyway I don't care about the virtual space, I care of what's taken on storage, of how much time I need to transfer or copy a file. That's what's matters.

    Just curious what's Hyper-V configuration version on Server 2025? is it 11? As I'm planning to move my VMs form Win11 and the current server 2022 Hyper-V version is 10, and I don't want to re-create and re-configure my 30+ VMs

    You have to recreate the VMs only in downgrading (unlike in VMware downgrade the version is not possible in HV).

    Older version works obviously in newer windows, you can *optionally* upgrade the version, but that's generally a stupid idea, if you want to use a VM in dual/multiple boot.

    That said W10 can run happily VMs from v 5.0 until W10 1909.

    Since W10 2004 all machines older than 8.0 are updated silently to 8.0 (which is pretty annoying given it's irreversible)
