how to fix Feature update to Windows 10, version 2004 failed - 0xc19001e1

I have a 1TB SSD on a high end computer built 2 years ago and it will not update, so I find it hard to believe "the issue is simply this:  There is not enough room on the C drive".

error code   0x80070714 when i use https://www.microsoft.com/en-us/software-download/windows10 and select update.

Standard windows update from Win 10 version 1909 still fails to update to 2004. MS needs to fix their own updates before they decide to send them out

Well, I guess this thread is mute now.  I've been following it since June, and tried absolutely everything mentioned herein, and was never able to successfully install 2004 :-(

Late last week, I noticed 2004 hadn't been an Update option for awhile, so I thought that I'd try again.

I went to the Microsoft Update site, and hit the latest Update key.

I DID disable my Norton virus software, but I had done that before to no avail.  I did nothing else, and let it run.

Much to my surprise, the Update installed effortlessly!

After it had finished, I went to system, and surprisingly in did not say 2004?  What had installed was Version 20H2!

The 1st glitch was my display.  I had to uninstall the display device it had assigned, and then reinstall my NVIDIA drivers and software.

Once I completed that, everything things to be working.

The only other thing happening is with my remote sound-card (which is used for recording music).  When I have it set as Default Sound, it works until I let the computer rest for an hour. When I go back, there is no sound!?  I must choose another sound device, confirm it, and then switch it back.  I will hopefully find a solution soon.

However, other than that, I am happy with 20H2!  

So anyway, everyone should try again to update from the Microsoft site.  It won't be 2004, but who needs it! LOL

I have a tera bite of space and it still won't download or install

The Windows 10 2004 update has been failing to install on my PC for the last few months (it tries to auto install every few weeks). I ran it manually and saw that it stops around 77% done and then does a restore of the prior OS version

I remembered I set up a Junction for the Windows Public folder a few years ago, and I ALWAYS have this issue on major Windows updates. Basically, I have a smaller C: drive and a huge D: drive. In each user account, Windows gives you the option of putting the users data files on a different drive than the System drive. No so for the "Public" folder. If you have set up a Junction for a Windows system folder (like Public), you much remove the Junction first and then run the install:

• To Remove Junction

(from command prompt administrative: WIN-key "cmd" then Ctrl+Shift+Enter to run it with admin privileges).....you won't lose the files on the target of the Junction. This just gets rid of the Junction.

cd %SYSTEMDRIVE%\Users

rmdir public

• Reboot the PC
• Run the Windows Updater from: https://www.microsoft.com/en-us/software-download/windows10%20
• After the upgrade succeeds (hopefully), recreate the Junction. You need to delete the new public folder that the Windows 10 upgrade created on the System drive and create a junction in its place. For this, boot into Safe Mode as an administrator and delete the public contents and folder using Cmd as an administrator. To remove the Public folder:

rmdir /s /q %SYSTEMDRIVE%\Users\Public

• Then recreate the Junction back to your actual Public folder on the secondary drive, from the Cmd app:

mklink /J  %SYSTEMDRIVE%\Users\Public D:\Users\Public

• Then reboot

This may not solve everyone's upgrade issue that is experiencing these upgrade symptoms posted in this thread, but there are a lot of PC's out there with dual drives on which users set up Junctions to move large system folders to a larger secondary drive.
