I have Windows 10 Version 1511 (OS Build 10586.494) successfully installed on my PC. I wish to upgrade to the latest Version 1607 (14393.10) using Windows 10 Update Assistant. It gives the following error after Updating reaches 2% completion. "Something went wrong. You can contact Microsoft Support for help with this error. Here is the error code 0x80070570."
I have tried the update process 5 times with the same result at 2% Updated. Can anyone help explain this error and how to get around it? Microsoft Support shows to do a manual install of Windows 10 (assuming one has an older OS) but I already have Windows 10 installed, this is just an upgrade.
Look forward to any help you can give.
