Hi @usulrasolas welcome to the farmOS forum! Sorry to hear you’re having trouble with Windows + Docker volumes. That seems to be a common issue for folks (not just in the farmOS community). I would suggest searching the forum - there have been a few others who had the same problem and figured it out eventually… I don’t use Windows so I’m afraid I can’t be much help other than pointing you to the other forum topics…
