Upgrade from Windows 10 (build 10240) fails at 40%

Question
-
Dear all,
I am looking for a solution to my upgrade issue. Currently I have build 10240 installed, but Windows thinks there is no upgrade out there, even when I tell it to Check for Updates. Clearly it is wrong, as there are many new updates available.
Manually downloaded ISOs all fail at 40% of the upgrade process, 23% in the installation of features and drivers.
When the system returns to the previously installed version of Windows I get the message "We couldn't install Windows 10" and the given error code is 0xC1900101 - 0x30018, with message "The installation failed in the FIRST_BOOT phase with an error during the SYSPREP operation"
I already tried a zillion things to have this resolved, including:
- Clean boot, so no other services that Microsoft's.
- Disabled the firewall and Windows Defender.
- Disabled the virus scanner.
- Disabled the automatic startup of programs at start-up.
- Disabled all .NET features in Windows (3.5 and 4.6).
- Updated all drivers.
Furthermore, I do not have a memory card inserted in the card reader, and all USB has been disconnected (except for the mouse).
So my last resort is you. I do have a log files in C:\$WINDOWS.~BT\Sources\Panther, but do not know how to attach these to this post.
Please suggest what I can do, except for a clean install, as I rather not do that.
