XBCD allows using the original Xbox Controller S on Windows. Windows 10 doesn’t allow installing unsigned drivers and XBCD has an unsigned driver. In order to instruct Windows to allow the installation you’ll have to:
- Press Start
- Click on Power
- Hold down Shift and press Restart
- Navigate to Troubleshoot -> Advanced options -> Startup Settings and press Restart
- Wait for Windows to restart and when prompted press 7 for Disable driver signature enforcement and wait for Windows to come up
- Install XBCD and allow it to install the driver
- Restart
