Installation

Ubuntu

https://docs.docker.com/installation/ubuntulinux

Windows

• Windows. It will install Boot2Docker management tool with ISO, Virtualbox and MYSYS-git UNIX tools.
• If the installer detects a version of VirtualBox installed, the VirtualBox checkbox will not be checked by default (Windows OS). The VirtualBox cannot be used anymore after updating my VB from 4.3.18 to 4.3.20.

Error in supR3HardenedWinReSpawn

The error may be related to Windows update.

The VB installation messed up. At the end I switch to VMware player. I cannot test Windows's Docker on my Windows machine.
