Reboot during AutoPilot ESP
This is a knowledgebase item to help you out with the reboot and logon twice issue during autopilot ESP.
The Autopilot reboot issue
During an AutoPilot enrollment the device with Windows 10 21H1 is rebooting, AutoPilot process will be paused, and the user must logon to the device for the second time.
This problem will occur when you are using Windows update for Business and Intune and your Update rings for Windows 10 and later is assigned to device group.
I have found the following in the Microsoft known issues documentation:
A reboot during Device setup will force the user to enter their credentials before transitioning to Account setup phase. User credentials aren’t preserved during reboot. Have the user enter their credentials then the Enrollment Status Page can continue.
The solution for the reboot during autopilot ESP issue
Assign Update rings for Windows 10 and later to a user group instead of device groups.
Now I am able to enroll my devices with AutoPilot without a second login prompt.
Check the following blog post and I will explain how I configure Windows Update for Business in an enterprise environment.
Install Windows 10 21H2 before you start rolling out.
Check you baseline applications if there are applications that needs a reboot.
Disable the Device Lock settings in Microsoft Security baseline or settings catalog
