Hello, I began to encounter the error code 800703F1 on my windows 8 while trying to update. I tried sfc /scannow, and I was told Windows resource Protection could not perform the requested operation. I ran the DISM tool but it told me windows database is corrupt (error 1009) after both commands. I ran windows update trouble shooter and got some problems not fixed (the problems are related to corrupt registry files). on this forum while searching for solution, I came across the idea of replacing a component file in the path C\windows\system32\config but someone said it is very risky with potential problems in the future. I could not use that solution besides he claimed he could easily solve such corruption problems without jeopardizing the safety of a system. please any help for me. windows automatic repair won't work (i.e it won't start), I tried to refresh my system but it said no changes were made, pls I need a solution. as I want to install the update kb 28713869 in order to update to windows 8.1
