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

I have same issue. One week ago tried to install update. Noticed there was uninstalled update for version 1909 but thought it would install 1st then 2004 update. Unfortunately the update failed and crashed Samsung notebook 9 pro laptop. Somehow after several trail and errors was able to restore the prior version later that night. So everything has been fine. Today 8/11 got notification there was an update waiting for restart so restarted the computer. When checked the update history discovered update was actually security-related along with a version 1909 update. However, there was also a version 2004 update pending download and install. So I allowed the download and install. It has taken at least 20 to 25 minutes for download and install. Now waiting after restart "this might take serial minutes don't turn off the pc" to complete.

It just completed and now laptop has has rebooted and I'm waiting on startup to finish. Startup has finished. I entered settings>update & security>view update history. It shows Feature Updates (1)

I selected and there as usual there are over 180 tips in 20 categories. 

Going back to desktop it appears so far the update was successful. 

Feature update to Windows 10, version 2004 failed to install all the way.  I have tried twice to get this update and both times it did not complete all the way / only 86% then failed.  When I check for updates again I get:

Feature update to Windows 10, version 2004

the next version of Windows is available with new features and security improvements.  When you're ready for update, select "Download and install"

Can someone help me with this update problem?

This problem was fixed.  

I got the solution from one of the Windows advisors on this forum, Andre Da Costa. I'm not able to search the original post to which he replied, so I'll paste his solution -

Open Start, type: CMD

Right click CMD

Click Run as administrator(if you don't run as administrator, the below commands may not work)

Then, type the below commands -

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Close Command Prompt, restart system and see if Windows Updates works.

The above solution helped me. I could finally install feature update to windows 10, version 2004 without any long pauses but it may take over 2 hours to complete the full installation.

I think Microsoft is "fixing" the 2004 update and rereleasing it later.

I did what you said, and it worked well.  Thank you.
