Import to your PC

You can import photos to your PC by connecting your device to your computer and using Windows Photos app:

1. Make sure that you have the latest version of iTunes on your PC. Importing photos to your PC requires iTunes 12.5.1 or later.
2. Connect your iPhone, iPad, or iPod touch to your PC with a USB cable.
3. You might need to unlock your iOS device using your passcode.
4. You might also see a prompt on the iOS device asking you to Trust This Computer. Tap Trust or Allow to continue.

Then, follow the steps in these Microsoft knowledge base articles to learn how to import photos to Windows Photos app:

• Windows 10
• Windows 8
• Windows 7

When you import videos from your iOS device to your PC, some might be rotated incorrectly in Windows Photos app. You can add these videos to iTunes to play them in the correct orientation.

If you have iCloud Photos turned on, you need to download the original, full resolution versions of your photos to your iPhone before you import to your PC. Find out how.

Photos and videos that you sync from your computer to your iOS device using iTunes can't be imported back to your computer. 

Learn what to do if you can't import photos from your iPhone, iPad, or iPod touch to your computer.

I am having the same problem ... I update both itunes and iphone, even apple watch ... now I can see the files but after starts the transfering it stops and says "A device attached to the system is not functioning". I am not sure what else I can do it ... you guys need to fix it ... and I also tried different apple cords and no luck either.

I JUST got off the phone with Apple support and there is a work around for new videos you can record, but it won't help for videos you've already created. (I also had the same issues and "Keep Originals" didn't work for me either as only the audio files would play with no video.)

Go into your settings

Go to camera

Go to formats

Make sure Most Compatible is checked (it defaults at High Efficiency)

Make a test video and try to transfer it. Mine worked like a charm and transferred pretty quickly with no issues. Playback was great as well and I didn't see any difference in video quality.

If anyone figures out a work around for videos already created, I would love to hear it.

I have this same problem. They keep telling me I need to use iTunes. Never had to use it before, not sure why I need it now. Can't wait til this contract is up and I can go back to android. I hate these "In order to use our product, you need to have 6 of our other products first.". Ridiculous.
