iTunes 12.5.1 will not see any of my devices. What can I do?

Hey kinnoeoin,

Thanks for participating in the Apple Support Communities. We're happy to look into iTunes for Windows with you.

If iTunes doesn‘t recognize your iPhone, iPad, or iPod, this article is a great troubleshooting resource to start with.

All the best.

Here is my fix

1. Uninstall iTunes, Bonjour, Apple Application Support both x32 and x64 versions if applicable, and the Apple Software Update.
2. Use CCleaner to remove any existing registry entries that are no longer needed.
3. Reinstall iTunes from the Apple website.
4. Plug your device in and it should work.

Hope This Helps
