is a popular open-source tool that can be used to easily install alternative USB drivers on Windows, including WinUSB and libusb. It provides a simple graphical interface to replace a device's default driver with a chosen one, such as WinUSB or the older libusbK/Libusb0 drivers.

Unlike older driver frameworks, UsbDk can be installed, updated, or uninstalled dynamically without restarting Windows.
