Use DISM to Repair Windows 10 Image

Yes, an in-place repair upgrade keeps all your installed apps and user files. A refresh would remove all installed apps.



Mount the ISO and run Setup, that's Step 4 in the tutorial.

thanks. I'll see if secure boot is enabled. going to give this a try in a bit.

Not sure that's relevant. You don't boot from the install media, you start the upgrade by running setup from within your existing Windows.

okay, tutorial said to disable secure boot. I'll run setup from the mounted ISO. thanks again.

Disabling secure boot for a repair install is more of a just to be extra safe instruction with older motherboards.

You should be fine without doing so, but if the repair install should fail, then try again with secure boot disabled.

Success! all is well after the in-place upgrade. windows update working again updates going in. thanks again.

Thanks, Bink for this tutorial.
I had been running DISM differently and it wasn't working for me. I followed your option 1, and after 2 weeks and many tries all failing to install 1803 I completed the in-place install

Dism /Online /Cleanup-Image /StartComponentCleanup "this one would stop at 20% and end"Dism /Online /Cleanup-Image /RestoreHealth "this one would run to 100% and find no errors"SFC /scannow "never showed any errors"

DISM

Is the Best tool I have ever used

Many thanks man
