itunes not responding

iTunes not responding every single time I connect my iPhone 6, my iPhone 5, any of my 3 iPads to my computer.

- Deleted iTunes and reinstalled.

- Deleted libraries and created others.

- Did the same thing in 3 different computers with 2 different iTunes IDs.

I give you one guess what happens after all these tries... iTunes not responding after I connect a device.

I'm talking about the latest version: iTunes Version 12.3.1.23 and Windows 10.

Any "genius" who can fix this before I take all my Apple devices for a full refund?
