iTunes for Windows has been replaced by the Apple Devices app. There are also several other ways to transfer videos from iPhone to a Windows PC:

1. Apple Devices app (Windows 10/11) — Install from the Microsoft Store. Connect your iPhone via USB, open Apple Devices, and use File Sharing to transfer videos.
2. Windows File Explorer (USB) — Connect your iPhone via USB, unlock the device, and tap Trust This Computer if prompted. Your iPhone appears in File Explorer under “This PC” as a portable device. Browse to Internal Storage → DCIM to find your videos.
3. iCloud for Windows — Install iCloud from the Microsoft Store, enable iCloud Photos on your iPhone, and photos/videos sync automatically to your PC.
4. AirDrop to Mac, then transfer — If you have a Mac nearby, AirDrop the video to it and then transfer to the Windows PC.
