Yes, it is possible to install Windows 10 on a Raspberry Pi 4, but with some limitations. Microsoft offers a Windows 10 called Windows 10 IoT Core, a lightweight version of Windows 10 designed for Internet of Things (IoT) devices, including the Raspberry Pi. However, Windows 10 IoT Core is not a complete desktop operating system and does not support running traditional Windows applications. Instead, it is designed to run Universal Windows Platform (UWP) apps specifically built for the Windows 10 ecosystem.
