Windows AppVMs sometimes fail to boot in Seamless GUI mode due to Safe Mode prompt appearing. Luckily it can be disabled using following commands in Command
Prompt:
bcdedit /set {bootmgr} displaybootmenu no
bcdedit /set {default} bootstatuspolicy ignoreallfailures
@Andrew can we add this to the readme and/or website documentation? If yes, I'll send PRs right away.
