This will require you to change settings on your computer's hardware. There is little risk to your computer but it is not for the faint of heart.

1. Restart, in BIOS settings, enable virtualization features [ press ‘Esc’, ‘delete’ or F10 depends on your hardware, go to BIOS settings -> Advanced -> device settings -> select virtualization checkbox(s) ]
2. As described in this documentation enable Hyper-V all checkboxes
3. Restart the system and then run Docker
