I've also tried doing the Windows 10 Pro version 21H1 using the Windows 10 Update Assistant, and also by using the Setup.exe file and other installation files from the Media Creation Tool.

In addition, when I've tried to do a Windows 10 Repair with an in-place upgrade using 20H2, to possibly help prepare the way for upgrading to version 21H1 it also fails at the same "working on updates.

It currently has Windows 10 Pro version 20H2, but whenever I try to install the update to 21H1, it always freezes at the point where the update says "working on updates 48%. I have successfully been able to update all of our family computers to Windows 10 version 21H1, except for my Dell Latitude E6440 laptop, which is being very stubborn. **** Edited - I was finally successful in upgrading to Windows 10 Pro version 21H1 please my subsequent post in this forum message thread.
