@acebmxer All looks good from the output. There might be some VMs that need fixes for Windows dbx updates to work properly, I'll try to add that in the official version.
Helped if i read the error message....
raise RuntimeError(f"{vm_type} {vm_uuid} is {power_state}, expected Halted; refusing to fix")
Shut down vm ran the fix again, and fix applied.
Edit - I did have to disable secure boot on windows vms for them to boot afterwards.
