Updates to Windows 10 keep failing

[blownsi]

Purchased my Ryzen 7 desktop refurbished early last year and I cloned a Sandisk 512 SSD in it.  The desktop worked fine for the first 6 months and then started failing to update Win10.  No matter which new update comes out it always gets to 45% and then fails installing and reverts to the previous (1703).  The current failure says the following:  Feature update to Windows 10, version 1803 x64 2019-05C - Error 0x80070002. 

I have tried the web's suggested manual install methods as well as using Windows update but both fail.  I have tried unplugging all USB devices, etc.  The only thing I can think of is either an issue with the Sandisk or the factory installed video card (RX550).  Looking for some advice.

Hello;
Allow me to welcome you to the HP Support Community!

I don't know what you've specifically tried but this article has some approaches you can consider:  

https://www.easeus.com/todo-backup-resource/solved-how-to-fix-error-code-0x80070002-in-windows-updat...

If those don't work, then you should consider using this tool to download and create Win10 install media: Windows 10 download

Once you have that, insert it into your PC (do NOT boot from it!!) find the folder containing the files, right-click on setup.exe and run it.  That will perform something known as a Repair-Install, which will Upgrade your Win10 but keep your data, settings, and apps.

The flash drive worked.  You were right, do not boot to it, simply right click on setup.
