Currently you do not need iTunes to transfer to a windows computer,

However it can help with backups and recovery, so is advisable to install it.

On a Windows 10 machine

Transfer photos from an iPhone to your PC.

First, connect your iPhone to a PC with a USB cable that can transfer files.

1. Turn your phone on and unlock it. Your PC can’t find the device if the device is locked.
2. On your PC, select the Start  button and then select Photos to open the Photos app.
3. Select Import > From a USB device, then follow the instructions. You can pick the items you want to import and select where to save them. Allow a few moments for detection and transfer.

Make sure the photos you want to import are actually on the device rather than in the cloud. Then, follow the steps for your type of device.
