question

Hi,

You can try the Windows 10 Update Assistant tool to check what it says, it will run prerequisites check and verify if your system meets the prerequisites.
One common issue is not having sufficient disk space on the OS drive.

It appears update 2004 has some issues and the update is being rolled out a little more slowly: https://www.computerworld.com/article/3561635/bumps-on-the-road-to-the-win10-version-2004-rollout.html

You might want to wait.

Why not to show this message prior to upgrade, not a hour after when it reaches 100%?

Hi everyone. I'm in almost the same boat; I'll explain by copying my post to another forum...

"Thanks for this info. Unfortunately for me it is a bit too late ! After an overnight, auto update of Windows 10 some days ago, I was greeted with a BSOD and the error message "Critical Path Died". After a few attempts to restart Win10 I was getting nowhere so, secure in the knowledge I had full back-ups of all my important files, I launched the nuclear option and did a re-install of Windows.
Success, in that Windows runs; failure because now I have winver 1511 and my "PC settings aren’t supported yet" ! I always find it encouraging when a fix makes matters worse... ;-)
In Microsoft Store all the programs are greyed out because my machine is not good enough to run them - even though they were installed and running before the update !
Come on, guys. You're driving me to Linux !!!"

Unfortunately this is not the first time an update has caused problems with my machine which is a fairly standard HP laptop. Normally it is fairly simple to find the reason - I am an expert on Clean Boot - but this time I can't find a way out...

Looking forward to some good news via Update Central !!

I had a similar problem. On a brand new ( a few weeks old) win10Pro desktop machine with a 450GB SSD, 2x2TB HD's, and 16GB RAM.. so, space wasn't the problem.
My machine would download the 2004 file, try to install, get part way, and then re-download the file again. After doing this a few times, I stopped the process, ran the 3.48GB file as Administrator and everything updated and installed within a few minutes. Fasted update I've ever experienced. Once I use the Admin route. Had I not done so, it would have just kept downloading yet another copy of 2004, getting part way done and repeating...

Windows 10, version 2004. Failed to install XX/XX/XXXX - 0xc1900223

I looked up the error code on https://support.microsoft.com/en-us/help/10587/windows-10-get-help-with-upgrade-installation-errors

Error

"What it means and how to fix it"

0xc1900223

This indicates that there was a problem downloading and installing the selected update. Windows Update will try again later and there is nothing you need to do at this time.

The machine is an Dell XPS 7390 which appears on the list that Dell have tested for Windows 10 May 2020

• Dell drivers are fully up-to-date.
  

• I have tried downloading the KB and installing but it said that it wasn't applicable http://www.catalog.update.microsoft.com/Search.aspx?q=KB4565503
  

• Tried installing using the Windows 10 Update Assistant and ISO media https://go.microsoft.com/fwlink/?LinkId=691209 "This PC can't be upgraded to Windows 10. Your PC settings aren't supported yet on this version of Windows 10. Microsoft is working to support your settings soon. No action is needed. Windows Update will offer this version of Windows 10 automatically when these settings are supported."
  

• Confirmed Core isolation disabled
  

• Tried disconnecting from the internet and upgrading
  

• Checked log files, but could not find any clues https://support.microsoft.com/en-gb/help/928901/log-files-that-are-created-when-you-upgrade-to-a-new-version-of-window

Supposedly the rollout has been delayed due to compatibility issues?

What is interesting I have another Dell XPS 7390 with the same settings and drivers and it upgraded without any problems.

Today I tried the installation of 2004 again by clicking the Fix Issues. And it installed.

The downloading doesn't seem to be the major locus of the problem. I had downloaded the install file several times (at 3+GB a throw) before heading down the path of installing as administrator. At which point, the installation (of a previously downloaded file that had "failed") all took place within a few minutes and not a glitch since.

I'd like to thank everyone again for all their input and help. I was able to successfully install the 2004 update the other night. The unfortunate news is that I didn't do anything different, obviously other than wait awhile. Using the Windows 10 update assistant seemed to work for me this time around, as long as you run it as administrator.

I should note, on the Windows Update settings, it still informed me my computer was not compatible for version 2004, but obviously the installer had no problems with finally upgrading me.
