As I started working with Docker, I ended up installing it on my main Windows system. Some time later, I needed to access a VM on that system and found that I was unable to do so at the same time Hyper-V was installed (a requirement for Docker). While it appears that this has been resolved by the latest Windows and VM software updates, I was able to find a utility to switch back and forth between Hyper-V/Docker and VMs.
