I restore my system to first day but again give me same error. last time i just restore windows and didnt install any program and start to update again i get same problem.

Hi,

For your problem, firstly, I would like to suggest you contact Samsung to verify whether the BIOS upgrade would effect system

Secondly, if updates configuration failed, can you access into system? if so, please check which updates configure failed.

Thirdly, you can check WindowsUpdates log and CBS log to find the reason of this problem. if you had difficult to analyze these log, you can provide them to us.

C:\Windows\WindowsUpdate.log

C:\Windows\Logs\CBS\CBS.log
