That stupid update crashed OS drive, making it unusable until I reinstalled Windows.  I ended up reinstalling with my older ISO I had on CD and let Windows 10 do all the updates afterwards, then I downloaded the updated ISO.  Microsoft will never get a class action lawsuit for all the times they broke people's computers and destroyed data.  Good thing I backup everything, but most people don't.

Hello
have you tried to repair it by using the DISM commands?
Analyze the Windows 10 image with DISM
Open a command prompt as an administrator.
Analyze the Windows 10 image to determine if it is damaged or not:
This operation may take several minutes.
You will get one of the following results:
"No damage to the component store has been detected"
it's perfect, the Windows 10 image is intact! 
You can run the command : 
but at first sight it is not your case
you probably have the message:

 this indicates that the image of Windows 10 is damaged.
So you have to check if the image of Windows 10 is intact, repairable or not repairable:

If the image of Windows 10 is damaged but repairable
Repair the Windows 10 system image:
If everything goes well, you should get the message

the Windows 10 image has been repaired successfully!
if you get an error message:

you have to repair it with the ISO of the version of your current Windows, but before, make sure to check the hash of your iso to avoid a corrupted win.
once done, mount the iso with daemontool or with windows explorer.
To repair the image of Windows 10 by specifying as source the installation file located in the ISO
Either you have an install.wim file so:
Or you have an install.esd file:
Replace X by the drive letter associated with the ISO image and N by the index of the Windows 10 edition to be repaired.
Detail of indexes and editions of Windows 10
The install.wim/install.esd file may contain several editions of Windows 10, identified by indexes:

You can find all the available indexes in the file install.wim/install.esd with the command :
To get more information about an index :
Now run the command again
the System File Checker tool should successfully run and repair any errors.
 

Hi Bob,
I've never done much with DISM, so I can I can only tell you what I suspect would be the case.
I don't think that the 2004 DISM will work with the 20H2 ISO. However, it will definitely work with the 2004 ISO.
Now 21H1 is about to be released, and I think that could trigger another forced upgrade for old releases. If I remember right, these releases have a life span of 1.5 years, meaning, you can only use 2004 for another couple of months before the next forced upgrade is due. Therefore, it could be better to upgrade straight to 20H2, which will last 6 more months until early 2022.
Let me answer both your post in one reply since they're connected.
You don't need an active internet connection to do a repair upgrade. Just make sure the connection is offline before you start setup. In my experience, repair upgrades fix almost any issue with the Windows installation.
And it's not over yet. After two years, my lawyer has finally made some progress on my data subject request, so let's wait and see what personal data Amazon has collected about me over the years.
That's not a bug. The two files seem identical but have different product IDs, so I decided to keep both in the list, in case one of them should disappear without prior announcement from Microsoft.
