Docker on Windows 10 under multiple users

Running windows 10, latest and updated for 03/07/2017. Installed Docker under my user account using admin permissions where appropriate. Logged into one of the admin accounts for the first time in a while, and noted that diskpart window was open when i hit the desktop and that most of my drive space was gone. Docker was trying to run but failing under both accounts. What is the expected Docker behavior under this condition? Is it trying to make more room under the second account?
