Using a usb cable, connect your device to your PC. You should get a small popup in thr bottom right corner. It should automatically start installing the required drivers for your PC to communicate with your device. Once connected, you may need to pull down the notification shade and change connection type to MTP.
After doing so, with your device unlocked, use your file explorer to open the contents of your device. Navigate to the fikes/pictures you need, then cut/copy/paste what ever you need to, to a folder on your pc.
