It sounds frustrating that iTunes isn't recognizing your iPhone anymore. Here are some steps you can try to troubleshoot the issue:

Update iTunes: Ensure that you have the latest version of iTunes. Sometimes, updates can resolve connectivity issues.

Check USB Connection:

Try using a different USB port on your computer. If possible, use a different USB cable to rule out cable issues. Trust This Computer: When you connect your iPhone to your computer, ensure that you unlock your iPhone and tap "Trust" when prompted.

Restart Apple Mobile Device Service:

Press Win + R, type services.msc, and hit Enter. Find "Apple Mobile Device Service," right-click it, and select Restart. Reinstall iTunes:

Uninstall iTunes and all related components (like Apple Mobile Device Support and Bonjour). Restart your computer and then reinstall iTunes from the Apple website. Check Device Manager:

Right-click on the Start menu and select Device Manager. Look for your iPhone under "Portable Devices." If there’s a yellow exclamation mark, it may indicate a driver issue. Right-click and select "Update driver." Disable Security Software: Temporarily disable any antivirus or firewall software to see if it’s interfering with the connection.

Update Windows: Ensure your Windows 10 is fully updated, as updates can sometimes resolve compatibility issues.

Check for iOS Updates: Make sure your iPhone is running the latest version of iOS.

If none of these steps work, you may want to reach out to Apple Support for further assistance.
