Windows 10: Having problems updating from 1809 to 1903 error messages

I have been having problems using various methods to update my computer to 1903

I tried using a bootable flash drive and running setup but it said something needed attention. This turned out to be the windows won't install with a flash drive plugged in thing. I tried using the windows upgrade assistant and I get these errors

Now when I try to run windows upgrade assistant it goes through the download lightning fast then verifies goes to installing windows 10 screen but eventually crashes out with these messages.

I feel like I am stuck now even after deleting the $WINDOWS.~BT folder to try and reset the whole download but that didn't work either









:)

 

Why don't I have 1903 when it tells me in the update screen that it was downloaded

In my list of previous update it tells me that 1903 was downloaded but I still have 1809.

Is there anyway for me to sort this out?

 

update to 1903

No, 1809 is not a pre-requisite for 1903

update 1903 sound problem

I have just updated to 1903, and have lost all sound. I have a Creative Audigy2 ZS Pro, yes, I know it's old, but it was working perfectly on build 1809.

After this 1903 update, no sound, so I went back to 1809, and hey presto, I got my sound back. I then tried the very latest 1903 build, but lost the sound again. Have MS got an answer? I will have to go back to 1809 if I want to hear anything, but can wait
a day or so if anyone at MS can give me a solution.
