I recently ran into an issue where I would plug my phone into my laptop, and each time it would ask if I wanted to trust the computer. I’d click trust, try to get into iTunes, and it still wouldn’t find my phone. So I’d unplug and re-plug in my phone, and lo and behold, it would ask if I wanted to trust my computer again… and again… and again.

Rebooting didn’t help. Updating iTunes didn’t help. So went out to find a solution.

I found a thread on Apple’s support community forums that had these steps that worked perfectly for me:

1. Connect your iPad/iPhone/iPod to your PC
2. Go to: Control Panel > Device Manager
3. Click on: Portable Devices
4. Right click on: Apple iPad/iPhone/iPod > Update Driver Software
5. Choose: Browse my computer for driver software.
6. Go to: C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers
7. Click okay and everything should suddenly work fine again.  (I can’t remember if I had to choose “trust” again, but if I did, I only had to do it the once and everything was fixed after that).

This worked just great on my Windows 10.
