I tried the WD first beta and it went well, when i updated to the beta 2 i deleted it because it never gave me an option to run or turn off it just automatically started up and hid itself somewhere in the background, no icon on the taskbar either. I use a program called "Whats running" that shows you everything running on your pc, WD was running. I thought that was too sneaky as i like to be able to switch a program on off whenever i wish. So i nuked it.
