My device does not appear in the iTunes window. Instead a separate window opens so I cannot sync

My device does not appear in the iTunes window. Instead a separate window opens so I cannot sync my device. I have tried with both my iPad, my iPod and my iPhone. In each case a separate window opens showing that it is fully connected to the computer, but it does not open in iTunes.

I have followed previous instructions to stop then start the device manager. I have even uninstalled then reinstalled iTunes, but no luck. Can someone help??
