Q: iTunes Not Recognizing Devices

I have this question too. Help! Need to back up my devices before I risk updating iOS

I have the exact same problem like you do!!!  My windows 10 pc is letting me upload my pictures and that is about it.  I would love to back up my phone once in a while even though I back it up to thru my wifi.  I am ready to start screaming!!

Here is a good place to start troubleshooting when iTunes doesn't recognize your device:

If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support

If your iOS device isn't showing in iTunes try the following:

1. Open Control Panel > Device Manager
2. Plug in your device
3. Locate Universal Serial Bus Controllers > Apple Mobile Device USB Driver.
   It is also possible the device may show under Imaging Devices, Portable Devices or Other Devices or as an MTB USB Device.
   
4. Right-click and select Update Driver Software...
5. Click Browse my computer for driver software
6. Browse to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers or
                   C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers
7. Click Let me pick from a list of device drivers on my computer
8. Click Apple Mobile Device USB Driver
9. Click Next, then Close and exit Device Manager

For step 3 above, open the device manager. Expand any of these sections that are listed.

• Universal Serial Bus Controllers
• Imaging Devices
• Portable Devices
• Other Devices

Connect the device. You should hear the telltale sound of Windows device connection and one section should gain a new entry. That should be your device. It may not be labelled correctly at this stage. If you don't hear a noise suspect a damaged cable.

Or try If iTunes doesn‘t recognize your iPhone, iPad, or iPod - Apple Support

Failing that try a full tear down and rebuild of iTunes as set out in Troubleshooting issues with iTunes for Windows updates.

Or lastly try rolling back to the last build of iTunes that worked for you. See iTunes installers for download links. If you're rolling back from 12.3.3.17 to 12.3.2.35, for example, then you'll also need to roll back the database in the way described in Empty/corrupt iTunes library after upgrade/crash. The tip includes suggestions for reintroducing any recent purchases so at worst you lose a few playcounts and/or a recently created playlist.
