My iPhone 6s not showing up in My Computer

Hi.

My iPhone 6s is recognized by my computer, appear in iTunes but is not listed with other devices in My Computer on my pc. I have two other iPhones 6 and 4s and both are listed and I can copy my photos with copy/paste. In devices and Printers my iPhone 6s is listed as unspecified although apple driver is installed.

Can anyone help me solve this issue?
