Windows 10: Win11 upgrade fails at 82% with error 0xc0000409

Clean boot, SFC, disabled firewall and virus check did not fix the problem. The error seems to come from Faulting module name: ntdll.dll Any help other than a complete new install is appreciated.

Windows 10 Creators Upgrade Error 0xc0000409

Hey,

Thanks, but I already tried what you suggested.

The laptop is fully compatible according to the upgrade assistant. Right before the download it checks the hardware and says it is ok. The drivers are updated and I have already tried the steps suggested in the upgrade and installation errors help page.
That's why I'm at a loss.

 

Windows Update, Error 0xc0000409

Can someone help me fix it?

 

Windows update fails at 82 percent consistently

I have been having trouble with Windows update failing repeatedly for several months. Every time I restart to complete installing an update, the computer prepares the update, shuts down, and restarts normally, but when it is installing the updates, it stops
at around 82% every time. The circle on the screen freezes, and it stays this way for up to 24 hours. Normally at that point, I hold the power button on my desktop to force it to restart. Then it says it's restoring the previous version of windows. The next
time I attempt to update my PC, the same thing happens. Is there anything I can do to stop this and complete the updates? I have been researching this problem online but haven't found any solutions that worked.

I tried the steps listed here, but they didn't work for me: https://answers.microsoft.com/en-us...two-days/d7dffdef-9f81-415e-aae5-73fb45dc97ec

When I entered the commands listed at the above link, I got a message that said "System Error 5 has occured. Access is denied."
