Intune Autopilot replace WDS or Sccm
Windows Autopilot does not technically install OS using pre-defined OS image like WDS/SCCM does. It actually uses local device image and configures it out-of-the-box. So Windows Autopilot is a NextGen replacement of WDS/SCCM, but for Windows 10 installations only. If you need to use a custom image, you have to use WDS/SCCM as before (or any other third-party alternative)
