TLDR: Update page shows "Your device is missing important security and quality fixes." for the last one week. It is still in Version 1909 Build 18363.1556.
Long story: It has been promising Feature update 2004 for quite a long time but did not really deliver. However, I had been getting regular security and quality minor updates. Around a month ago, when I started getting the end of service notifications for 1909 I tried to force updates by hitting "Check for updates" and it tried doing a huge download for 20H2. I think after a long installation process it aborted around 45% and rolled back. Tried a couple of times and the same result.
Now, I did a few methods suggested in various forums and Microsoft support sites like running update troubleshooter, a scan, running commands as administrator, setting right a few registry entries etc. I even rolled the last cumulative update for 1909 KB5003169 and it got reinstalled on the next reboot but the "Your device is missing important security and quality fixes." returned.
I am worried because I will be missing out important security updates given that 1909 has reached the end of service.
UPDATE: The error code against the update 20H2 update is given as 0xC1900101
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
After running the script from tenforums I tried running the updates. It was the same result, downloaded, installed, restarted, blue screen with progress percentage and shuts down at around 45%. Restarting it shows "Trying to recover installation" and then "Undoing changes made...". No difference.
Looks like Repair upgrade is the only option left.
Good Day Curious_userCA,
Proceed with the Repair upgrade, keep us posted with the results, if you have any question reach out to us here in the community anytime.
Have a wonderful day ahead and stay safe.

Hi Carlo,
Unfortunately, repair upgrade didn't work for me as well.
Like I had mentioned earlier, when the computer restarts after downloading and installing, it shows "working on updates xx%". Everytime in the past ten or so times, including the Repair upgrade, it stops at 48% and shuts down.
This time I was able to see it very briefly flash a message, something like "Windows could not configure the update " or something to that effect .
Looks like I have run out of all options. Let me know if there is any.
Good Day Curious_userCA
