Device manager still showing error symbol

It popped up in the notifications area saying this 'iPhone is installed and ready to go'
What does USBDeview show for the drivers? There should be at least 3 (1 for each of the modes) - 1. Still Imaging (MTP), 2. Vendor Specific (for data transfer with iTunes) and 3. Unknown (for DFU mode). Your screenshot only shows the MTP driver but doesn't show whether it's the Apple or Microsoft MTP driver in use.

(I've attached a CFG file for USBDeview. Unzip it and stick it in the same folder as USBDeview. Run USBDeview as administrator and it will pick up the CFG file and show the same columns view as my screenshot in post #25 plus the driver manufacturer. Both drivers (WUDFRd.sys and usbaapl64.sys) need to be Apple (Vendor ID: 05ac/Product ID:12a8) for full functionality with iTunes and no issues in Device Manager. USBDeview.zip)

Windows is weird in that it will assign a fresh record of another (duplicated) driver if you connect your iPhone into a different USB port or if you connect another iOS device into the same port. USBDeview will show all these records, even though the multiple records point to - in this case - just 3 Apple modes enabled by 2 Apple drivers (WUDFRd.sys and usbaapl64.sys). That's why my screenshot in post #25 shows multiple apparently duplicated driver entries for a single USB port but only one iPhone record... it's because I also have an iPad and an iPad Mini... and I always use the same port (because of a bug in MS' USB device enumeration... but that's a different story).

Unfortunately, the default MS MTP driver will prevent the more functional Apple driver (usbaapl64.sys which supports a further 2 device modes other than MTP) from installing... which is what I suspect you are experiencing. You have to remove the basic MS driver then install the Apple driver (usbaapl64.sys). The installation of iTunes usually does this automatically... or it can be force-installed using usbaapl64.inf (usually found in C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers.)

Note: It's not that the default MS MTP driver is bad (it works fine in conjunction with Win 10's AutoPlay) but it only supports transfer of photos/videos and nothing else. iTunes uses it's own enhanced-capability drivers to support the 2 additional modes (data transfer and DFU). iTunes will not work with MS' limited capability driver... and I suspect this is deliberate on Apple's part.

Hope this helps...
