Hello Concetto,

It can be a computer specific issue. My windows 7 Home edition is working fine with WD Security and my Windows 7 Professional computer is not compatible with WD Security.

It is a Windows service related issue which causes such behavior with many WD software.

There is Windows 10 related KBA on support website which can be helpful for you to look over into the issue. Support KBA is given below.
