You can use the My Cloud Desktop program for Windows (http://setup.wd2go.com/index.php?mod=download&device=mc), or for mobile devices use the WD My Cloud app for Android or iOS to stream media remotely from a My Cloud device.
If one has the older first generation v4.x single bay My Cloud units they can install the CloudDAVMod (https://community.wd.com/t/app-clouddavmod-various-versions-for-firmware-v4-09-2016/161543) which allows one to use a web browser to access and stream media through their web browser remotely, and to map the My Cloud remotely to their computer.
