I have a 2TB My Cloud (Gen1) … Windows 7 … No Software Installed (ie no My Net, no WD Smartware, no Goodsync etc) and the My Cloud just appears under “Network” and i just click on it and go to the public folder or my external drive attached to the My Cloud… and can upload and download files using Windows copy and move function.
For local network access one does not need to use any WD programs or software. One would use the Windows File Explorer or the Macintosh Finder to access their My Cloud on the local network.
For remote access to a My Cloud not on the local network one would use either MyCloud.com web portal or if using a mobile device, the WD My Cloud app for iOS or Android.
The My Cloud Desktop program has been End of Life since 2016. Recent firmware updates to the My Cloud have rendered that program non functional.
If one is having trouble seeing or accessing their local network My Cloud when using Windows 10, make sure SMB1.0/CIFS is enabled. Microsoft typically disables this option in recent updates to, or new installs of, Windows 10.
