Windows 10: Failed to Install 1903

I originally upgraded from Windows 7 to Windows 10 when Microsoft offered the free upgrades and have never had any Windows Update issues until now... running 64 bit.
Timeline:
1. Using Windows Update I tried updating to 1903 a couple of days ago and it failed to install showing 0xc19001e1. Avast & Malwarebytes were disabled. I did forget to unplug my USB printer and scanner.

2. I ran CHKDSK and it found and fixed errors.

3. I ran Windows Update again and it also failed showing 0xc1900101 .

4. Ran DISM tool and showed no corruption.

5. Ran Windows Troubleshooter.

6. I since have downloaded the Media Creation Tool but haven't tried it yet. Once I click on it to start the installation am I reinstalling Windows or updating to 1903... I've never used this tool before?

KB4025339 Fails Install 0x80070564


Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!

 

Windows Updates failed to instal

I just did step one and they have just all installed.... thank you so much.... it was quite frustrating having that update window pop up every 5 minutes and failing to instal every time

Thanks mate

 

After installing windows 10 1903 Sage Report Designer fails to start

After installing windows 10 1903 Sage Report Designer fails to start. Yesterday there was no problem before the update.

Seems to be a rights issue:

DOESN'T WORK:

• logged in to Win 10 under my own account (with administrator rights)
• logged in to Win 10 under my own account and run Sage as an administrator

DOES WORK:

• logged in to Win 10 using the administrator account (that I had to activate)

Is this a known issue for 1903? Will it be fixed?
