Hi Sharath, WSUS is not part of the scope of Autopatch, and if using SCCM, the requirement is for you to swing over the Windows Updates policies workload to either Pilot Intune or Intune. The updates management engine Autopatch uses is the Windows Updates for Business (WUfB) engine which is fully in the cloud. In this case, devices download the updates bits from either the Microsoft in the internet or from other peers utilizing delivery optimization. Let me know if you have additional questions.
