Task Sequence(Windows 10 1903) progress hidden with screen stuck on screen “Just a moment…”
While Running Task Sequence to deploye custom image for Windows 10 version 1903, task Sequence doesn't show any progress bar in Full OS Mode.
Task Sequence progress bar works fine until WinPE Phase which includes image applying and download of "Setup Windows and configmgr". Right after the reboot when we are expecting to start Full OS phase starting with SCCM Client installation, there is blue screen shown with message "Just a moment..." till the time all the all the steps of task sequence completes successfully.
This doesn't bring a good customer experience.

Hi Manish!
To remove the "Just a moment" screen, simply change your unattended.xml. You will never see that screen during reboot.
This will not resolve the slow start of the SCCM client during reboots, but you will see the SCCM progress bar.

Why add yet another reboot and cause an additional 5 minutes or so due to the client initialization delay. This issue has been around for at least two years. Fix the issue :/

I am seeing this on SCCM 1809 suddenly did not seem to be an issue until recently and seems to show up on SSD drives

With CM 1906 now the debugger also hangs behind the "Just a moment..." screen, only adding skipoobe (which we should not use) fixes the problem

Thanks Remi Lilleskare, adding restart step right after SCCM client solves this issue.
However, restart wasn't the requirement for previous versions.

Add a reboot right after the system center client install in your TS.
Problem solved.
