@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.
Well sadly that's not the end of the story. After running just fine for a week or two, including multiple reboots in the early stages of installing apps etc, the most recent reboot (to install some sort of 'touchscreen driver' update) has caused a reoccurrence of this issue.
After a few tries, and leaving the VM off for a few minutes, I managed to get it to boot up again, but there is clearly some sort of issue here.
