Windows 10: Repeated update failure, stuck in 2004 version

Windows is not updating. I have used both the normal update process and the Windows Update Assistant. I ran the troubleshooter for updates and it says it solved some problems, but it doesn't show me what they were. It starts with a slow download of the update, then slowly prepares for the update. I am prompted to restart my computer to install the update. I do so and the computer reboots, the update quickly starts installing at 40%, then reboots again and hits about 68% before jumping to 70% and then back to 67% before rebooting again and failing and entering a almost instantaneous tr

Repeated Failure to Update, stuck on version 1809

Hi,

I am Sumit, an Independent Advisor and a 3 year Windows Insider MVP here to help.

Try updating to 2004 using Media Creation tool and if it fails, share the logs.

The fastest way to get the upgrade is through Media creation tool or ISO file.

Please download Media Creation Tool from the link below and select Upgrade this PC at the first screen.

All steps, including upgrading using ISO file and Media creation tool, are covered here:

Meanwhile, if the update fails with MCT as well.

Let us check the Installation log to find why the update failed. Please share the logs as mentioned in this article. You should use a File sharing service like Onedrive or Media Fire to upload files and share the link in the next reply.

Stuck in Windows 10 Upgrade

My computer seems to be stuck in a Windows 10 failed upgrade loop. I was running fine on a beta version of Windows 10, and then I came downstairs one morning to see it repeatedly booting, attempting to repair, then rebooting. The steps I've taken to diagnose are:

• Attempting to boot off a USB drive (with all drives disabled in BIOS) - this fails at the point of the blue windows screen
  
• Attempting to boot the machine itself and getting into "repair/safe mode" using F7
  
• Looking at the BIOS for obvious failures (e.g. RAM that should be there is missing) - nothing obvious is wrong.
  

I am fairly certain the build version was 9926. For many months, the system would attempt to upgrade, and then say "it failed" for some reason and roll back.

Suggestions for next steps?
