When a Windows 11 computer fails to immediately recognize a Realtek-based USB Ethernet chip (such as the widespread or RTL8156 chipsets), the hardware triggers its built-in flash storage. Windows then mounts a virtual CD drive and attempts to run rtk-nic-driver-installer.sfx.exe to bridge the gap. Why the "RTL_UL Phantom Drive" Loop Happens on Windows 11

The file size is unusually small (under 2 MB) or excessively large (over 200 MB).
It is highly recommended to extract the archive manually and install the driver via Device Manager rather than running the .exe directly. This bypasses potential compatibility issues with the aging setup wrapper script and ensures a cleaner driver installation on the Windows 11 kernel. Ideally, obtaining the driver directly via Windows Update or the motherboard manufacturer's website is preferred over using a standalone SFX executable. Select Run anyway
