Not enough memory to start Docker

are we saying that turning down the memory slider helps docker memory startup problems?
or are these docker startup memory problems caused by hyper-v?

I normally start docker from my cmd terminal or sometimes from my win git-bash terminal. Are there switches that can be passed when calling the win docker exe? like a memory one?

thank you in advance. -Rob

Follow up:
Switching cpu and mem to min allowed me to get docker restarted
Cleaned up containers with "docker ps -a"
Switching back: Docker now runs with max 2 cpu’s and 2048 memory settings
