Multiple Error Codes while updating to Cumalitive Version 1703

ive tried all known solutions

- well, as you've not listed them, people will probably suggest things you've tried... so might help to say what you've tried.

Have you tried
- the Windows update troubleshooter
- the tutorial on resetting Windows Update
- manually downloading 1803 and upgrading without updating during the process
- inspecting the Windows update logs

And have you tried disabling any security solutions - or uninstalling them?
Disconnecting unnecessary peripherals?
Checking your files - from an admin command or Powershell prompt
chkdsk C: /F
(restart needed)

SFC /Scannow

Do you have > 25Gb free space on C: say?

How much free space do you have on C: ?
And could you post a screenshot of your partitions, expanding columns as necessary to show all text?

Inspect the Update logs:

A list of some log files:
C:\Windows\Panther
C:\$Windows.~BT\Sources\Panther
The Panther logs are often hidden. Configure file explorer so that you can view hidden files.
setuperr.log
setupact.log
setupapi.dev.log
Setupmem.dmp
BlueBox.log

If a manual upgrade fails, you could try doing an in-place upgrade repair install of your existing build first, if that will run.

Else try Tweaking.com's free repair tool, easy to find, choose only repairs related to Windows Update and restoring services in the first instance.

Strongly recommended- make sure you have an up to date disk image of Windows so you can restore it if something goes wrong. E.g. Macrium reflect (free) - we constantly urge users to use disk imaging routinely.
